FKIE_CVE-2025-64509

Vulnerability from fkie_nvd - Published: 2025-11-10 22:15 - Updated: 2025-11-12 16:19
Severity ?
7.5 (High) - CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H
Summary
Bugsink is a self-hosted error tracking tool. In versions prior to 2.0.6, a specially crafted Brotli-compressed envelope can cause Bugsink to spend excessive CPU time in decompression, leading to denial of service. This can be done if the DSN is known, which it is in many common setups (JavaScript, Mobile Apps). The issue is patched in Bugsink 2.0.6. The vulnerability is similar to, but distinct from, another brotli-related problem in Bugsink, GHSA-fc2v-vcwj-269v/CVE-2025-64508.

En versiones anteriores a la 2.0.6, un sobre comprimido con Brotli especialmente dise\u00f1ado puede hacer que Bugsink consuma un tiempo excesivo de CPU en la descompresi\u00f3n, lo que lleva a una denegaci\u00f3n de servicio. Esto se puede lograr si se conoce el DSN, lo cual ocurre en muchas configuraciones comunes (JavaScript, aplicaciones m\u00f3viles). El problema est\u00e1 parcheado en Bugsink 2.0.6.
