brace-expansion: Brace-expansion: Denial of Service due to exponential-time complexity
A flaw was found in brace-expansion. An attacker can exploit a vulnerability in the expand function by providing a specially crafted string. This string, containing consecutive non-expanding brace groups, can trigger exponential-time complexity, leading to significant CPU consumption and event-lo...

BIT-OPENBAO-2025-52894 OpenBao Vulnerable to Unauthenticated Rekey Operation Cancellation
OpenBao exists to provide a software solution to manage, store, and distribute sensitive data including secrets, certificates, and keys. OpenBao before v2.3.0 allowed an attacker to perform unauthenticated, unaudited cancellation of root rekey and recovery rekey operations, effecting a denial of...
CVE-2026-64278
The CVE-2026-64278 issue affects the Linux kernel i2c driver for imx-lpi2c on some i.MX platforms. A workqueue can trigger I2C transfers while hardware resources (clock/pinctrl) are disabled or not yet restored during the suspend/noirq suspend ā resume_noirq window, risking access to I2C register...
GHSA-FFPJ-XV5C-P3GW Open WebUI: ReDoS in skill-mention regexes causes whole-instance DoS on default config
Summary Two regexes in backend/openwebui/utils/middleware.py that parse skill-mention tags backtrack in OnĀ² on input that contains . Both run synchronously, on the asyncio event loop, on every chat completion with no feature gate. Because the default deployment is a single uvicorn worker, one suc...

Summary The fix released in jackson-core 2.18.6 and 2.21.1 for GHSA-72hv-8253-57qq Number Length Constraint Bypass in Async Parser, published 2026-02-28 is incomplete. The fix commit b0c428e6 1555 wired validateIntegerLength into a new setIntLength helper and called it at every place where the...
Tornado: Quadratic DoS via Repeated Header Coalescing
Summary The HTTPHeaders.add method in Tornado accumulates values using string concatenation when the same header name is repeated. Due to Python string immutability, each concatenation copies the entire string, resulting in OnĀ² time complexity. Given Tornado's single event loop architecture, a...

PYSEC-2026-2650 misp-modules has nsafe remote resource fetching in expansion
An unsafe remote resource fetching vulnerability existed in MISP Modules expansion modules. The htmltomarkdown module accepted arbitrary HTTPS URLs without sufficient validation, which could allow Server-Side Request Forgery against loopback, private, or link-local network resources. Additionally...
PYSEC-2026-2458 docling-graph has SSRF via Missing Internal IP Validation in URLInputHandler
Impact The URLInputHandler class in doclinggraph/core/input/handlers.py makes HTTP requests to user-supplied URLs without validating whether the target resolves to a private, loopback, or link-local IP address. The URLValidator only checks for a valid scheme and non-empty netloc, performing no...
PYSEC-2026-2484 FastChat has Denial of Service Through Blocking Event Loop in Model Workers (Incomplete Fix for ff66426)
A security vulnerability has been detected in lm-sys fastchat up to 0.2.36. This issue affects the function apigenerate of the component Worker API Endpoint. The manipulation leads to resource consumption. The attack can be initiated remotely. The exploit has been disclosed publicly and may be...
