View online: https://www.drupal.org/sa-core-2025-003

Project: Drupal core [1]
Date: 2025-February-19
Security risk: *Moderately critical* 14 ∕ 25
AC:Complex/A:Admin/CI:All/II:All/E:Theoretical/TD:Uncommon [2]
Vulnerability: Gadget Chain

Affected versions: >= 8.0.0 < 10.3.13 || >= 10.4.0 < 10.4.3 || >= 11.0.0 <
11.0.12 || >= 11.1.0 < 11.1.3
Description: 
Drupal core contains a potential PHP Object Injection vulnerability that (if
combined with another exploit) could lead to Arbitrary File Inclusion.
Techniques exist to escalate this attack to Remote Code Execution. It is not
directly exploitable.

This issue is mitigated by the fact that in order for it to be exploitable, a
separate vulnerability must be present to allow an attacker to pass unsafe
input to unserialize(). There are no such known exploits in Drupal core.

Solution: 
Install the latest version:

 * If you use Drupal 10.3.x, update to Drupal 10.3.13 [3]
 * If you use Drupal 10.4.x, update to Drupal 10.4.3 [4]
 * If you use Drupal 11.0.x, update to Drupal 11.0.12 [5]
 * If you use Drupal 11.1.x, update to Drupal 11.1.3 [6]

All versions of Drupal 10 prior to 10.3 are end-of-life and do not receive
security coverage. (Drupal 8 [7] and Drupal 9 [8] have both reached
end-of-life.)
