AI-suggested

A patch is available in filelock version 2.19.0_2 that fixes this vulnerability. Users should upgrade to this version or later to remediate the issue. No additional mitigation is required if the patch is applied. The vulnerability requires local write access to the lock's parent directory or creation of the lock directory in a sticky directory by the attacker, so restricting such access also reduces risk.

Description

CVE-2026-112941 is a local integrity vulnerability in filelock's SoftReadWriteLock and AsyncSoftReadWriteLock implementations. A local user with write access to the lock's parent directory can replace the lock directory tree with symbolic links after the lock's initial acquire, causing the lock user process to write lock records through the symlinked paths. This results in the lock user's process deleting or replacing files in directories it can write, such as a private git repository, disrupting its operation. The vulnerability requires specific conditions involving sticky directories or writable parent directories and affects filelock versions 4.1.0 through 4.2.0. The CVSS score is low (3.3) due to local attack vector, low integrity impact, and no confidentiality or availability impact. A fix is available in version 2.19.0_2.
