Security advisories: Drupal core – Critical – Drupal core – Critical – Third-party libraries – SA-CORE-2021-004

Project: 
Date: 
2021-July-21
Vulnerability: 
Drupal core – Critical – Third-party libraries
CVE IDs: 
CVE-2021-32610
Description: 
The Drupal project uses the pear Archive_Tar library, which has released a security update that impacts Drupal.

The vulnerability is mitigated by the fact that Drupal core’s use of the Archive_Tar library is not vulnerable, as it does not permit symlinks.

Exploitation may be possible if contrib or custom code uses the library to extract tar archives (for example .tar, .tar.gz, .bz2, or .tlz) which come from a potentially untrusted source.

This advisory is not covered by Drupal Steward.

Solution: 
Install the latest version:

Versions of Drupal 8 prior to 8.9.x and versions of Drupal 9 prior to 9.1.x are end-of-life and do not receive security coverage.
