View online: https://www.drupal.org/sa-contrib-2026-041

Project: Commerce Core [1]
Date: 2026-June-03
Security risk: *Moderately critical* 14 ∕ 25
AC:Basic/A:None/CI:Some/II:Some/E:Theoretical/TD:Uncommon [2]
Vulnerability: Cross site scripting

Affected versions: >= 3.3.0 < 3.3.6
CVE IDs: CVE-2026-10769
Description: 
The module doesn't sufficiently sanitize customer comments in the order
receipt email template; this could be exploited to achieve Cross-site
Scripting (XSS).

This vulnerability is mitigated by the fact that it only affects
installations with Checkout (commerce_checkout) enabled, and the "Comments"
checkout pane (id: customer_comments) is explicitly used, which is disabled
by default.

Solution: 
Install the latest version:

 * If you use Commerce Core 3.3.x, upgrade to Commerce Core 3.3.6 [3]
