SCA: security update for filelock (GHSA-fq56-3cx3-fjxp)

medium Tenable Self-Hosted Container Security Plugin ID 477811

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - filelock is a platform-independent file lock for Python. From 3.22.0 until 4.2.1, SoftFileLock can break a
 stale marker after an attacker frees its own marker following the stale read, an honest contender creates
 a live successor on the reused inode, and the successor's modification time is not newer than the saved
 observation, causing the live marker to be removed and two holders to be admitted. This issue is fixed in
 version 4.2.1. (CVE-2026-112935)

Solution

Update the filelock library and its related packages to version 4.2.1 or later.
