| CVE-2026-34445 | Hig | 0.49 | 8.6 | 0.00 | Apr 1, 2026 | Open Neural Network Exchange (ONNX) is an open standard for machine learning interoperability. Prior to version 1.21.0, the ExternalDataInfo class in ONNX was using Python’s setattr() function to load metadata (like file paths or data lengths) directly from an ONNX model file. It didn’t check if the "keys" in the file were valid. Due to this, an attacker could craft a malicious model that overwrites internal object properties. This issue has been patched in version 1.21.0. | |
| CVE-2026-30077 | Hig | 0.49 | 7.5 | 0.00 | Mar 30, 2026 | OpenAirInterface V2.2.0 AMF crashes when it fails to decode the message. Not all decode failures result in a crash. But the crash is consistent for particular inputs. An example input in hex stream is 80 00 00 0E 00 00 01 00 0F 80 02 02 40 00 58 00 01 88. | |
| CVE-2026-4987 | Hig | 0.49 | 7.5 | 0.00 | Mar 28, 2026 | The SureForms – Contact Form, Payment Form & Other Custom Form Builder plugin for WordPress is vulnerable to Payment Amount Bypass in all versions up to, and including, 2.5.2. This is due to the create_payment_intent() function performing a payment validation solely based on the value of a user-controlled parameter. This makes it possible for unauthenticated attackers to bypass configured form payment-amount validation and create underpriced payment/subscription intents by setting form_id to 0. | |
| CVE-2026-33894 | Hig | 0.49 | 7.5 | 0.00 | Mar 27, 2026 | Forge (also called `node-forge`) is a native implementation of Transport Layer Security in JavaScript. Prior to version 1.4.0, RSASSA PKCS#1 v1.5 signature verification accepts forged signatures for low public exponent keys (e=3). Attackers can forge signatures by stuffing “garbage” bytes within the ASN structure in order to construct a signature that passes verification, enabling Bleichenbacher style forgery. This issue is similar to CVE-2022-24771, but adds bytes in an addition field within the ASN structure, rather than outside of it. Additionally, forge does not validate that signatures include a minimum of 8 bytes of padding as defined by the specification, providing attackers additional space to construct Bleichenbacher forgeries. Version 1.4.0 patches the issue. | |
| CVE-2026-30576 | Hig | 0.49 | 7.5 | 0.00 | Mar 27, 2026 | A Business Logic vulnerability exists in SourceCodester Pharmacy Product Management System 1.0 in the add-stock.php file. The application fails to validate the "txtprice" and "txttotalcost" parameters during stock entry, allowing negative financial values to be submitted. This leads to corruption of financial records, allowing attackers to manipulate inventory asset values and procurement costs. | |
| CVE-2026-30575 | Hig | 0.49 | 7.5 | 0.00 | Mar 27, 2026 | A Business Logic vulnerability exists in SourceCodester Pharmacy Product Management System 1.0 in the add-stock.php file. The application fails to validate the "txtqty" parameter during stock entry, allowing negative values to be processed. This causes the system to decrease the inventory level instead of increasing it, leading to inventory corruption and potential Denial of Service by depleting stock records. | |
| CVE-2025-59032 | Hig | 0.49 | 7.5 | 0.00 | Mar 27, 2026 | ManageSieve AUTHENTICATE command crashes when using literal as SASL initial response. This can be used to crash ManageSieve service repeatedly, making it unavailable for other users. Control access to ManageSieve port, or disable the service if it's not needed. Alternatively upgrade to a fixed version. No publicly available exploits are known. | |
| CVE-2026-33250 | Hig | 0.49 | 7.5 | 0.00 | Mar 24, 2026 | Freeciv21 is a free open source, turn-based, empire-building strategy game. Versions prior to 3.1.1 crash with a stack overflow when receiving specially-crafted packets. A remote attacker can use this to take down any public server. A malicious server can use this to crash the game on the player's machine. Authentication is not needed and, by default, logs do not contain any useful information. All users should upgrade to Freeciv21 version 3.1.1. Running the server behind a firewall can help mitigate the issue for non-public servers. For local games, Freeciv21 restricts connections to the current user and is therefore not affected. | |
| CVE-2025-15606 | Hig | 0.49 | 7.5 | 0.00 | Mar 23, 2026 | A Denial-of-Service (DoS) vulnerability in the httpd component of TP-Link's TD-W8961N v4.0 due to improper input sanitization, allows crafted requests to trigger a processing error that causes the httpd service to crash. Successful exploitation may allow the attacker to cause service interruption, resulting in a DoS condition. | |
| CVE-2025-22453 | Hig | 0.49 | 7.5 | 0.00 | Feb 10, 2026 | Improper input validation for some Server Firmware Update Utility(SysFwUpdt) before version 16.0.12 within Ring 3: User Applications may allow an escalation of privilege. System software adversary with a privileged user combined with a high complexity attack may enable local code execution. This result may potentially occur via local access when attack requirements are present without special internal knowledge and requires no user interaction. The potential vulnerability may impact the confidentiality (high), integrity (high) and availability (high) of the vulnerable system, resulting in subsequent system confidentiality (none), integrity (none) and availability (none) impacts. | |
| CVE-2026-0919 | Hig | 0.49 | 7.5 | 0.00 | Jan 27, 2026 | The HTTP parser of Tapo C210 v3, C220 v1 and C520WS v2 cameras improperly handles requests containing an excessively long URL path. An invalid‑URL error path continues into cleanup code that assumes allocated buffers exist, leading to a crash and service restart. An unauthenticated attacker can force repeated service crashes or device reboots, causing denial of service. | |
| CVE-2025-43494 | Hig | 0.49 | 7.5 | 0.00 | Dec 12, 2025 | A mail header parsing issue was addressed with improved checks. This issue is fixed in iOS 18.7.2 and iPadOS 18.7.2, iOS 26.1 and iPadOS 26.1, macOS Sequoia 15.7.2, macOS Sonoma 14.8.2, macOS Tahoe 26.1, visionOS 26.1, watchOS 26.1. An attacker may be able to cause a persistent denial-of-service. | |
| CVE-2025-43401 | Hig | 0.49 | 7.5 | 0.00 | Nov 4, 2025 | A denial-of-service issue was addressed with improved validation. This issue is fixed in macOS Sequoia 15.7.2, macOS Sonoma 14.8.2, macOS Tahoe 26.1. A remote attacker may be able to cause a denial-of-service. | |
| CVE-2011-20001 | Hig | 0.49 | 7.5 | 0.00 | Oct 14, 2025 | A vulnerability has been identified in SIMATIC S7-1200 CPU V1 family (incl. SIPLUS variants) (All versions < V2.0.3), SIMATIC S7-1200 CPU V2 family (incl. SIPLUS variants) (All versions < V2.0.3). The web server interface of affected devices improperly processes incoming malformed HTTP traffic at high rate. This could allow an unauthenticated remote attacker to force the device entering the stop/defect state, thus creating a denial of service condition. | |
| CVE-2025-59532 | Hig | 0.49 | — | 0.00 | Sep 22, 2025 | Codex CLI is a coding agent from OpenAI that runs locally. In versions 0.2.0 to 0.38.0, due to a bug in the sandbox configuration logic, Codex CLI could treat a model-generated cwd as the sandbox’s writable root, including paths outside of the folder where the user started their session. This logic bypassed the intended workspace boundary and enables arbitrary file writes and command execution where the Codex process has permissions - this did not impact the network-disabled sandbox restriction. This issue has been patched in Codex CLI 0.39.0 that canonicalizes and validates that the boundary used for sandbox policy is based on where the user started the session, and not the one generated by the model. Users running 0.38.0 or earlier should update immediately via their package manager or by reinstalling the latest Codex CLI to ensure sandbox boundaries are enforced. If using the Codex IDE extension, users should immediately update to 0.4.12 for a fix of the sandbox issue. | |
