medium Tenable Self-Hosted Container Security Plugin ID 462361

Description

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

 - rsync before 3.5.0 contains a symlink race condition vulnerability in the --remove-source-files feature
 that allows attackers with symlink creation access to cause arbitrary file deletion. Attackers can
 atomically substitute a symlink for a source file between transfer completion and the unlink() call,
 causing rsync to delete the symlink target rather than the intended source file. (CVE-2026-53800)

Solution

Update the rsync library and its related packages to version 3.5.0 or later.
