CVE-2026-62268: borgbackup Archive Extraction Vulnerability

%55

Short explanation

CVE-2026-62268 is a vulnerability in borgbackup where extracting maliciously crafted archives can cause out-of-tree files outside the extraction directory to be modified or deleted via symlinks or path traversal sequences.

Why does it matter?

This vulnerability may allow attackers to overwrite or delete external files. However, an attacker requires repository access and, for encrypted repositories, the borg key and passphrase.

What should be done?

  • Do not share borg keys and passphrases with potential attackers for encrypted repositories
  • Do not share repository access with potential attackers for any repository type
  • Follow vendor advisories and apply available updates
