CVE-2025-23166Hig0.497.50.00May 19, 2025The C++ method SignTraits::DeriveBits() may incorrectly call ThrowException() based on user-supplied inputs when executing in a background thread, crashing the Node.js process. Such cryptographic operations are commonly applied to untrusted inputs. Thus, this mechanism potentially allows an adversary to remotely crash a Node.js runtime.
CVE-2024-43357Hig0.498.60.01Aug 15, 2024ECMA-262 is the language specification for the scripting language ECMAScript. A problem in the ECMAScript (JavaScript) specification of async generators, introduced by a May 2021 spec refactor, may lead to mis-implementation in a way that could present as a security vulnerability, such as type confusion and pointer dereference. The internal async generator machinery calls regular promise resolver functions on IteratorResult (`{ done, value }`) objects that it creates, assuming that the IteratorResult objects will not be then-ables. Unfortunately, these IteratorResult objects inherit from `Object.prototype`, so these IteratorResult objects can be made then-able, triggering arbitrary behaviour, including re-entering the async generator machinery in a way that violates some internal invariants. The ECMAScript specification is a living standard and the issue has been addressed at the time of this advisory's public disclosure. JavaScript engine implementors should refer to the latest specification and update their implementations to comply with the `AsyncGenerator` section. ## References - https://github.com/tc39/ecma262/commit/1e24a286d0a327d08e1154926b3ee79820232727 - https://bugzilla.mozilla.org/show_bug.cgi?id=1901411 - https://github.com/boa-dev/boa/security/advisories/GHSA-f67q-wr6w-23jq - https://bugs.webkit.org/show_bug.cgi?id=275407 - https://issues.chromium.org/issues/346692561 - https://www.cve.org/CVERecord?id=CVE-2024-7652
CVE-2024-3052Hig0.497.50.00Apr 26, 2024Malformed S2 Nonce Get command classes can be sent to crash the gateway. A hard reset is required to recover the gateway.
CVE-2024-3051Hig0.497.50.00Apr 26, 2024Malformed Device Reset Locally command classes can be sent to temporarily deny service to an end device. Any frames sent by the end device will not be acknowledged by the gateway during this time.
CVE-2016-10363Hig0.497.50.01Jun 16, 2017Logstash versions prior to 2.3.3, when using the Netflow Codec plugin, a remote attacker crafting malicious Netflow v5, Netflow v9 or IPFIX packets could perform a denial of service attack on the Logstash instance. The errors resulting from these crafted inputs are not handled by the codec and can cause the Logstash process to exit.
CVE-2025-44019Hig0.467.10.00Jun 12, 2025AVEVA PI Data Archive products are vulnerable to an uncaught exception that, if exploited, could allow an authenticated user to shut down certain necessary PI Data Archive subsystems, resulting in a denial of service. Depending on the timing of the crash, data present in snapshots/write cache may be lost.
CVE-2025-24836Hig0.467.10.00Feb 13, 2025With a specially crafted Python script, an attacker could send continuous startMeasurement commands over an unencrypted Bluetooth connection to the affected device. This would prevent the device from connecting to a clinician's app to take patient readings and ostensibly flood it with requests, resulting in a denial-of-service condition.
CVE-2026-41585Med0.426.50.00May 8, 2026ZEBRA is a Zcash node written entirely in Rust. From zebrad versions 2.2.0 to before 4.3.1 and from zebra-rpc versions 1.0.0-beta.45 to before 6.0.2, a vulnerability in Zebra's JSON-RPC HTTP middleware allows an authenticated RPC client to cause a Zebra node to crash by disconnecting before the request body is fully received. The node treats the failure to read the HTTP request body as an unrecoverable error and aborts the process instead of returning an error response. This issue has been patched in zebrad version 4.3.1 and zebra-rpc version 6.0.2.
CVE-2026-25577Hig0.427.50.00Feb 10, 2026Emmett is a framework designed to simplify your development process. Prior to 1.3.11, the cookies property in mmett_core.http.wrappers.Request does not handle CookieError exceptions when parsing malformed Cookie headers. This allows unauthenticated attackers to trigger HTTP 500 errors and cause denial of service. This vulnerability is fixed in 1.3.11.
CVE-2025-62370Hig0.427.50.00Oct 15, 2025Alloy Core libraries at the root of the Rust Ethereum ecosystem. Prior to 0.8.26 and 1.4.1, an uncaught panic triggered by malformed input to alloy_dyn_abi::TypedData could lead to a denial-of-service (DoS) via eip712_signing_hash(). Software with high availability requirements such as network services may be particularly impacted. If in use, external auto-restarting mechanisms can partially mitigate the availability issues unless repeated attacks are possible. The vulnerability was patched by adding a check to ensure the element is not empty before accessing its first element; an error is returned if it is empty. The fix is included in version v1.4.1 and backported to v0.8.26.
CVE-2025-7338Hig0.427.50.00Jul 17, 2025Multer is a node.js middleware for handling `multipart/form-data`. A vulnerability that is present starting in version 1.4.4-lts.1 and prior to version 2.0.2 allows an attacker to trigger a Denial of Service (DoS) by sending a malformed multi-part upload request. This request causes an unhandled exception, leading to a crash of the process. Users should upgrade to version 2.0.2 to receive a patch. No known workarounds are available.
CVE-2025-36539Med0.426.50.00Jun 12, 2025AVEVA PI Data Archive products are vulnerable to an uncaught exception that, if exploited, could allow an authenticated user to shut down certain necessary PI Data Archive subsystems, resulting in a denial of service.
CVE-2025-29785Hig0.427.50.00Jun 2, 2025quic-go is an implementation of the QUIC protocol in Go. The loss recovery logic for path probe packets that was added in the v0.50.0 release can be used to trigger a nil-pointer dereference by a malicious QUIC client. In order to do so, the attacker first sends valid QUIC packets from different remote addresses (thereby triggering the newly added path validation logic: the server sends path probe packets), and then sending ACKs for packets received from the server specifically crafted to trigger the nil-pointer dereference. v0.50.1 contains a patch that fixes the vulnerability. This release contains a test that generates random sequences of sent packets (both regular and path probe packets), that was used to verify that the patch actually covers all corner cases. No known workarounds are available.
CVE-2025-47944Hig0.427.50.00May 19, 2025Multer is a node.js middleware for handling `multipart/form-data`. A vulnerability that is present starting in version 1.4.4-lts.1 and prior to version 2.0.0 allows an attacker to trigger a Denial of Service (DoS) by sending a malformed multi-part upload request. This request causes an unhandled exception, leading to a crash of the process. Users should upgrade to version 2.0.0 to receive a patch. No known workarounds are available.
CVE-2025-20054Med0.426.50.00May 13, 2025Uncaught exception in the core management mechanism for some Intel(R) Processors may allow an authenticated user to potentially enable denial of service via local access.
CVE-2024-43367Hig0.427.50.00Aug 15, 2024Boa is an embeddable and experimental Javascript engine written in Rust. Starting in version 0.16 and prior to version 0.19.0, a wrong assumption made when handling ECMAScript's `AsyncGenerator` operations can cause an uncaught exception on certain scripts. Boa's implementation of `AsyncGenerator` makes the assumption that the state of an `AsyncGenerator` object cannot change while resolving a promise created by methods of `AsyncGenerator` such as `%AsyncGeneratorPrototype%.next`, `%AsyncGeneratorPrototype%.return`, or `%AsyncGeneratorPrototype%.throw`. However, a carefully constructed code could trigger a state transition from a getter method for the promise's `then` property, which causes the engine to fail an assertion of this assumption, causing an uncaught exception. This could be used to create a Denial Of Service attack in applications that run arbitrary ECMAScript code provided by an external user. Version 0.19.0 is patched to correctly handle this case. Users unable to upgrade to the patched version would want to use `std::panic::catch_unwind` to ensure any exceptions caused by the engine don't impact the availability of the main application.
CVE-2024-38525Hig0.427.50.00Jun 28, 2024dd-trace-cpp is the Datadog distributed tracing for C++. When the library fails to extract trace context due to malformed unicode, it logs the list of audited headers and their values using the `nlohmann` JSON library. However, due to the way the JSON library is invoked, it throws an uncaught exception, which results in a crash. This vulnerability has been patched in version 0.2.2.
CVE-2026-42545Med0.385.90.00May 12, 2026Granian is a Rust HTTP server for Python applications. From 0.2.0 to 2.7.4, Granian aborts a worker process if a WSGI application returns an invalid HTTP response header name or value. The WSGI response conversion path uses .unwrap() on both the header name and header value constructors, so malformed output from the application becomes a process abort instead of a handled error. This vulnerability is fixed in 2.7.4.
CVE-2026-34944Med0.375.70.00Apr 9, 2026Wasmtime is a runtime for WebAssembly. Prior to 24.0.7, 36.0.7, 42.0.2, and 43.0.1, On x86-64 platforms with SSE3 disabled Wasmtime's compilation of the f64x2.splat WebAssembly instruction with Cranelift may load 8 more bytes than is necessary. When signals-based-traps are disabled this can result in a uncaught segfault due to loading from unmapped guard pages. With guard pages disabled it's possible for out-of-sandbox data to be loaded, but this data is not visible to WebAssembly guests. This vulnerability is fixed in 24.0.7, 36.0.7, 42.0.2, and 43.0.1.
CVE-2026-5937Med0.365.50.00Apr 27, 2026Insufficient parameter verification leads to the occurrence of format errors in files, which will trigger an unhandled "std::invalid_argument" exception, ultimately causing the program to terminate.
