SCA: security update for borgbackup (GHSA-gfp8-w835-v44j)

medium Tenable Self-Hosted Container Security Plugin ID 474693

Description

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

 - borgbackup is an opensource, deduplicating archiver with compression and authenticated encryption. Prior
 to 1.4.5 and 2.0.0b22, extracting a malicious archive can follow a symlinked parent path or resolve
 embedded dot-dot path components and delete or overwrite files outside the extraction directory. A crafted
 slave hardlink can also use an attacker-controlled hardlink source outside the extraction directory and
 hard-link that file into the restored tree, disclosing its contents. Creating the malicious archive
 requires repository access and, for encrypted or authenticated repositories, the Borg key and passphrase;
 a victim must then extract the archive. This issue is fixed in versions 1.4.5 and 2.0.0b22.
 (CVE-2026-62268)

Solution

Update the borgbackup library and its related packages to version 1.4.5 or later.
