GHSA-W9V7-R27G-JRMX

Vulnerability from github – Published: 2025-03-03 09:30 – Updated: 2025-03-03 09:30

Details

By default, the affected code is not executed unless one of the following conditions is met:

LWS_WITHOUT_EXTENSIONS (default ON) is manually set to OFF in CMake. LWS_WITH_HTTP_STREAM_COMPRESSION (default OFF) is manually set to ON in CMake. Despite these conditions, when triggered in affected configurations, this vulnerability may allow attackers to manipulate pointers, potentially leading to memory corruption or unexpected behavior.

Severity ?

10.0 (Critical)
