Drupal core - SA-CORE-2020-013

  • Disclosed: 25.11.2020
  • Updated: 11.10.2026 13:17

The Drupal project uses the PEAR Archive_Tar library. The PEAR Archive_Tar library has released a security update that impacts Drupal. For more information please see:

Multiple vulnerabilities are possible if Drupal is configured to allow .tar, .tar.gz, .bz2, or .tlz file uploads and processes them.

To mitigate this issue, prevent untrusted users from uploading .tar, .tar.gz, .bz2, or .tlz files.

This is a different issue than SA-CORE-2019-012. Similar configuration changes may mitigate the problem until you are able to patch.
