Project: Typogrify [1]
Date: 2024-January-10
Security risk: *Moderately critical* 12∕25
AC:Basic/A:User/CI:Some/II:Some/E:Theoretical/TD:Uncommon [2]
Vulnerability: Cross Site Scripting

Affected versions: <1.3.0
Description: 
The Typogrify module brings the typographic refinements of Typogrify to
Drupal. It provides a text filter and a Twig filter.

The typogrify Twig filter can be used to bypass the Twig auto-escape feature,
leading to a persistent Cross Site Scripting (XSS) vulnerability.

This vulnerability is mitigated by the fact that it is only exposed when the
twig filter is specifically used in a template to render content.

Solution: 
Install the latest version:

  * If you use the Typogrify module for Drupal 10.x, upgrade to Typogrify
    8.x-1.3 [3]

If you use the typogrify Twig filter provided by this module, then this
update may cause double-encoding of text. See the updated README for best
practices.
