medium Tenable Cloud Security Plugin ID 477223

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 4.1.0 until 4.2.1, SoftFileLock versions
 from 4.1.0 can reuse a stale observation when an attacker pre-dates and removes its own marker, at least
 two lock-user processes are waiting, coarse or matching modification times preserve the observation, and
 an honest contender creates a fresh marker on the reused inode, causing that live marker to be removed as
 stale. This issue is fixed in version 4.2.1. (CVE-2026-112906)

Solution

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