high Tenable Self-Hosted Container Security Plugin ID 445959

Description

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

 - Previously, resolving relative paths containing parent directory ('..') segments performed string
 conversions and buffer rewrites on each step, resulting in quadratic time complexity and high memory
 allocation overhead. Now, path resolution operates on a byte buffer using index-based backtracking for
 '..' segments, eliminating the quadratic time complexity and significantly reducing memory allocations.
 (CVE-2026-56860)

Solution

Update the stdlib library and its related packages to version 1.25.13 or later.
