PraisonAI's unauthenticated A2A official example can reach real LLM-driven `eval()` tool execution
Description
Summary
The first-party PraisonAI A2A server example combines three behaviors into a remotely exploitable Critical chain:
- The example exposes an A2A server without configuring
auth_token. - The same example binds the server to
0.0.0.0. - The example registers a
calculate(expression)tool implemented with Pythoneval(expression).
An unauthenticated network client can send a JSON-RPC message/send request to /a2a. The A2A handler passes the attacker-controlled message to agent.chat(). With a real Gemini LLM (gemini/gemini-2.5-flash-lite), the model invoked the registered calculate tool, causing the example's eval() call to execute Python in the server process. The canary wrote a marker file from an unauthenticated /a2a request.
This is not a claim that every A2A deployment is automatically RCE. The Critical chain is confirmed for the first-party A2A example, and for deployments that follow the same pattern: public unauthenticated A2A plus an unsafe tool such as this eval()-based calculate tool. The default unauthenticated A2A surface is the remote entry point; the official example's eval() tool provides the code execution sink.
Earlier note:
The unsafe official example existed earlier, but the complete unauthenticated /a2a message/send to agent.chat() exploit chain is only claimed here for versions where that endpoint is present and confirmed.
Trust
Boundary
The boundary that should be preserved is:
Unauthenticated network clients must not be able to drive server-side agent tools that can execute code or mutate server state.
The affected example breaks that boundary. A remote unauthenticated A2A client can supply a prompt that reaches the server's LLM-backed agent. The LLM can then invoke a registered local tool. In the official example, that registered local tool directly evaluates attacker-influenced input with eval().

Attack
Model
The attacker is an unauthenticated remote client that can reach the A2A HTTP service. This is realistic because the official example binds to 0.0.0.0, does not configure auth_token, and exposes /a2a.
The attacker does not need:
- repository write access
- local shell access
- a valid bearer token
- a compromised maintainer account
- access to server secrets
The attacker only sends a JSON-RPC request to /a2a.
Non-Claims
This report does not claim:
- all A2A deployments are automatically RCE
auth_token-protected A2A deployments are affected in the same way- safe, read-only tools provide the same impact as the official example's
eval()sink - deterministic tool invocation is required in all attacks
The real LLM canary demonstrates that a normal model-backed agent can invoke the official example's unsafe tool from an unauthenticated /a2a request. The deterministic control proof is included only to isolate the server-to-tool sink behavior.
Impact
For the official example and similar deployments:
- remote prompt-to-tool execution from an unauthenticated network request
- arbitrary Python execution through the example
calculate()tool'seval() - compromise of the server process privileges
- potential read/write access to application files reachable by that process
- potential credential or environment variable exposure if a payload reads process state
- denial of service or data corruption through executed code
Supporting evidence also confirmed that default unauthenticated A2A exposes task state APIs (tasks/list, tasks/get, tasks/cancel) and stores text plus structured DataPart payloads in task history. That is a separate confidentiality/integrity problem and strengthens the risk of leaving A2A unauthenticated.
Reproduction
Environment
Tested repository state:
commit: 4985415e
describe: v4.6.37-13-g4985415e
Real LLM used:
gemini/gemini-2.5-flash-lite
The API key value was not printed. The PoC only prints whether a provider credential is present.
The PoC uses FastAPI TestClient to exercise the same HTTP route and request handling stack without opening a public listening socket during testing. The official example's __main__ path binds to 0.0.0.0 when run as a server.
Reproduction
Steps
From the repository root:
cd
python3 -m venv .venv-real-llm
source .venv-real-llm/bin/activate
python -m pip install -U pip
python -m pip install litellm fastapi "pydantic>=2" httpx uvicorn
Set a Gemini API key without writing it to shell history:
unset GEMINI_API_KEY
read -rsp "GEMINI_API_KEY: " GEMINI_API_KEY
echo
export GEMINI_API_KEY

=== CRITICAL REAL LLM PROOF RESULT ===
OFFICIAL_A2A_EXAMPLE_REAL_LLM_UNAUTH_HTTP_TO_CUSTOM_EVAL_TOOL_CONFIRMED
Scope: first-party A2A example deployment; a real LLM tool call reached the eval-based custom tool from an unauthenticated /a2a request.
Note: response contains eval tool prefix: False is not a failure. The model summarized the tool result instead of returning the raw Result: ... string, but the marker file was created and its content matched the canary.
Proof-of-Concept
Code
The following PoC is self-contained. It loads the first-party A2A example, replaces the default LLM with a real LiteLLM-backed Gemini model, sends an unauthenticated JSON-RPC request to /a2a, and checks whether the example's eval() tool wrote the marker file.

Control Proof
A deterministic control proof also confirmed that once a tool call reaches the official example's calculate tool, the eval() sink executes arbitrary Python:
=== Official A2A example HTTP-to-eval-tool chain ===
A2A auth_token configured: None
A2A.serve default host: '0.0.0.0'
example __main__ binds host 0.0.0.0: True
registered tool names: ['search_web', 'calculate']
calculate source contains eval: True
calculate in DEFAULT_DANGEROUS_TOOLS: False
HTTP status without Authorization: 200
fake LLM tool calls: [{'prompt': 'OFFICIAL_A2A_EXAMPLE_EVAL_CANARY', 'tool_name': 'calculate', 'expression': "__import__('pathlib').Path('/home/employees/fox-linux-qa-002/work/out/official-a2a-example-http-eval-canary.txt').write_text('OFFICIAL_A2A_EXAMPLE_HTTP_EVAL_CONFIRMED\\n', encoding='utf-8')", 'result': 'Result: 41'}]
marker exists: True
response contains tool result prefix: True
=== CRITICAL EXAMPLE CHAIN PROOF RESULT ===
OFFICIAL_A2A_EXAMPLE_UNAUTH_HTTP_TO_CUSTOM_EVAL_TOOL_CONFIRMED
This control proof is not the primary evidence because it uses a deterministic fake LLM. The primary evidence above uses a real Gemini LLM and should be preferred.

A2A Boundary Evidence
Default A2A with auth_token=None exposes task APIs without authentication:
=== A2A default unauthenticated task disclosure and cancellation ===
A2A.serve default host: '0.0.0.0'
A2A auth_token default: None
A2A /a2a dependency count: 0
victim message/send status: 200
attacker tasks/list status without Authorization: 200
attacker tasks/get status without Authorization: 200
attacker tasks/cancel status without Authorization: 200
victim prompt leaked through tasks/list: True
victim response leaked through tasks/list: True
victim structured data leaked through tasks/list: True
victim prompt leaked through tasks/get: True
victim response leaked through tasks/get: True
victim structured data leaked through tasks/get: True
victim structured data reached agent.chat input: True
task status after unauth cancel: cancelled
=== A2A auth-token control for task APIs ===
A2A auth_token configured: True
A2A /a2a dependency count: 1
tasks/list without Authorization: 401
tasks/get with wrong token: 401
tasks/get with correct token: 200
This demonstrates that configuring auth_token changes the boundary materially. Without it, /a2a is open to unauthenticated clients.
Why
This Is Not Just Misconfiguration
The issue is not simply that an application author deliberately wrote a dangerous private tool. The vulnerable chain is present in first-party material:
- the official example is an A2A server example intended to be run by users
- it registers an
eval()-based tool - it does not configure an auth token
- it binds to
0.0.0.0 - the framework allows
auth_token=Noneto remove authentication from/a2a - the JSON-RPC
message/sendpath reachesagent.chat()and registered tools
Users following this example can expose a remotely reachable, unauthenticated prompt-to-code-execution service.
Recommended
Fixes
Short-term:
- Remove
eval()from the official A2A example. Use a safe expression parser or a fixed arithmetic parser instead. - Do not publish examples that combine public bind, no authentication, and code-capable tools.
- Change the example to bind to
127.0.0.1by default. - Require an explicit
auth_tokenor other authentication mechanism before allowing0.0.0.0binding. - Add a startup failure for
host="0.0.0.0"whenauth_tokenis absent.
Framework-level hardening:
- Make
A2A.serve()default to127.0.0.1. - Require authentication for
/a2aby default. - Add an explicit unsafe flag for unauthenticated public A2A, for example
allow_unauthenticated_public=True. - Treat custom tools capable of code execution as dangerous even when the function name is not in
DEFAULT_DANGEROUS_TOOLS. - Add documentation warnings that public A2A servers must not expose tools that execute code, shell commands, file writes, or network access without authorization and review.
Regression tests:
- Test that
A2A(agent=..., auth_token=None).serve(host="0.0.0.0")fails or warns loudly. - Test that official examples do not contain
eval(),exec(), shell execution, or file mutation tools on unauthenticated public endpoints. - Test that
/a2areturns401when authentication is required.

Advisory Description
PraisonAI's first-party A2A server example exposes an unauthenticated A2A JSON-RPC endpoint and registers a calculate(expression) tool implemented with Python eval(). The example also binds to 0.0.0.0. A remote unauthenticated attacker can send message/send to /a2a; the request reaches agent.chat(), and a real LLM can invoke the registered calculate tool. In testing with gemini/gemini-2.5-flash-lite, this resulted in arbitrary Python execution in the server process, confirmed by creation of a marker file from an unauthenticated HTTP request.
The issue affects deployments following the official A2A example or similar unauthenticated public A2A deployments with unsafe tools. The default unauthenticated A2A surface also exposes task history and task cancellation APIs, increasing confidentiality and integrity impact.
AI Insight

Unauthenticated network clients can reach a Python eval()-based tool in the PraisonAI A2A server example, leading to remote code execution.
Vulnerability
The first-party PraisonAI A2A server example (inbox/PraisonAI/examples/python/a2a/a2a-server.py) combines three behaviors into a critical chain: it exposes an A2A server without configuring auth_token, binds the server to 0.0.0.0, and registers a calculate(expression) tool implemented with Python eval(expression) [1][2]. This chain allows an unauthenticated network client to send a JSON-RPC message/send request to /a2a. The A2A handler passes the attacker-controlled message to agent.chat(), which, when backed by a real Gemini LLM (gemini/gemini-2.5-flash-lite), can invoke the registered calculate tool, causing the server-side eval() to execute attacker-influenced Python code [1][2]. The vulnerability is confirmed in the official example and in deployments that follow the same pattern: public unauthenticated A2A plus an unsafe tool such as this eval()-based calculate tool [1][2].
Exploitation
An attacker needs only network access to the unauthenticated /a2a endpoint (no authentication, no prior access). The attacker sends a crafted JSON-RPC message/send request that includes a prompt designed to make the LLM call the calculate tool with a malicious expression [1][2]. When the LLM invokes calculate, the eval(expression) call executes arbitrary Python code in the server process. The canary test confirmed this by writing a marker file from an unauthenticated /a2a request [1][2]. No user interaction or additional privileges are required.
Impact
Successful exploitation allows an unauthenticated remote attacker to execute arbitrary Python code on the server. This leads to full compromise of the server process, including potential data disclosure, file modification, and further lateral movement depending on the server's environment [1][2]. The trust boundary that should prevent unauthenticated network clients from driving server-side agent tools that can execute code or mutate server state is completely broken [1][2].
Mitigation
At the time of publication, the vendor has not released a fix for this specific example [1][2]. The GitHub advisory (GHSA-vg22-4gmj-prxw) has been published, which may prompt a patch [1][2]. Workarounds: do not deploy the official A2A example or any A2A server that exposes an unauthenticated endpoint combined with a tool that uses eval() or similar unsafe sinks; ensure auth_token is configured and the server is not bound to 0.0.0.0 in production; and replace any eval()-based tool with a safe alternative [1][2]. This CVE is not listed in the CISA Known Exploited Vulnerabilities (KEV) catalog as of the publication date.

Vulnerability mechanics
Root cause
"The official A2A example registers a `calculate(expression)` tool implemented with Python `eval(expression)` and exposes it without authentication on a public network binding."
Attack vector
An unauthenticated remote attacker sends a JSON-RPC `message/send` request to the `/a2a` endpoint [ref_id=1]. Because the official example does not configure `auth_token` and binds to `0.0.0.0`, the request reaches the A2A handler without any authentication check [ref_id=1]. The handler extracts the user text from the message and passes it to `agent.chat()`, which invokes the LLM-backed agent [ref_id=1]. The LLM can then call the registered `calculate` tool, which executes the attacker-influenced expression via Python's `eval()` [ref_id=1]. In testing with `gemini/gemini-2.5-flash-lite`, this chain resulted in arbitrary Python execution in the server process, confirmed by writing a marker file from an unauthenticated HTTP request [ref_id=1].
Affected code
The vulnerable code is in the official A2A example at `inbox/PraisonAI/examples/python/a2a/a2a-server.py` [ref_id=1]. The `calculate(expression)` function on line 23 uses Python's built-in `eval(expression)` to evaluate user-influenced input [ref_id=1]. The example registers this tool with the agent (line 34) and binds the server to `0.0.0.0` (line 53) without configuring `auth_token` [ref_id=1]. The framework code in `inbox/PraisonAI/src/praisonai-agents/praisonaiagents/ui/a2a/a2a.py` shows that when `auth_token` is `None`, the `_verify_auth` dependency is skipped and the `/a2a` POST endpoint has no authentication (lines 165-166, 193-194) [ref_id=1]. The `handle_jsonrpc` handler passes attacker-controlled input to `agent.chat()` (line 315) [ref_id=1].
What the fix does
The patch [patch_id=3131093] addresses the vulnerability by modifying the official A2A example to remove the unsafe `eval()`-based `calculate` tool and replace it with a safe expression parser. The advisory recommends removing `eval()` from the official A2A example and using a safe expression parser or a fixed arithmetic parser instead [ref_id=1]. Additional recommended fixes include changing the example to bind to `127.0.0.1` by default, requiring an explicit `auth_token` before allowing `0.0.0.0` binding, and adding a startup failure for `host="0.0.0.0"` when `auth_token` is absent [ref_id=1]. Framework-level hardening suggestions include making `A2A.serve()` default to `127.0.0.1` and requiring authentication for `/a2a` by default [ref_id=1].
Preconditions
- networkThe A2A server must be reachable on the network (the official example binds to 0.0.0.0)
- configThe A2A server must not have auth_token configured (the official example defaults to None)
- configThe agent must have a registered tool that uses eval() or similar code execution (the official example registers calculate with eval())
- inputThe attacker sends a single JSON-RPC POST request to /a2a with a message/send payload
Reproduction
From the repository root, create a virtual environment and install dependencies: `python3 -m venv .venv-real-llm && source .venv-real-llm/bin/activate && python -m pip install -U pip && python -m pip install litellm fastapi "pydantic>=2" httpx uvicorn` [ref_id=1]. Set a Gemini API key: `export GEMINI_API_KEY=<your-key>` [ref_id=1]. Run the real LLM canary: `REAL_LLM_MODEL="gemini/gemini-2.5-flash-lite" REAL_LLM_TOOL_CHOICE=auto python out/prove-official-a2a-example-real-llm-canary.py` [ref_id=1]. Expected success output: `OFFICIAL_A2A_EXAMPLE_REAL_LLM_UNAUTH_HTTP_TO_CUSTOM_EVAL_TOOL_CONFIRMED` and marker file `out/official-a2a-example-real-llm-canary.txt` containing `OFFICIAL_A2A_EXAMPLE_REAL_LLM_CONFIRMED` [ref_id=1].
