Project: Paragraphs [1]
Date: 2026-June-24
Security risk: *Moderately critical* 11 ∕ 25
AC:Basic/A:None/CI:None/II:Some/E:Theoretical/TD:Uncommon [2]
Vulnerability: Access bypass

Affected versions: <1.21.0
CVE IDs: CVE-2026-13241
Description: 
The optional Paragraphs Library module allows the reuse of paragraphs in
multiple places.
The module doesn't sufficiently restrict access to direct child paragraphs of
library items through API endpoints.
This vulnerability is mitigated by the fact the paragraphs_library module
must be in use and general write access to paragraphs through another module
must be allowed.

Solution: 
Install the latest version:

 * If you use the Paragraphs module for Drupal 8.x, upgrade to Paragraphs
   8.x-1.21 [3]

Reported By: 
 * Mustafa Ahmed (mustafa007) [4]

Fixed By: 
 * Sascha Grossenbacher (berdir) [5]

Coordinated By: 
 * Greg Knaddison (greggles) [6] of the Drupal Security Team
 * Juraj Nemec (poker10) [7] of the Drupal Security Team
