SCA: security update for contao/comments-bundle (GHSA-628f-v4f6-p37r)

critical Tenable Self-Hosted Container Security Plugin ID 474047

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - Contao is an Open Source CMS. From version 4.0.0 until 5.3.50 and 5.7.12, an unauthenticated visitor can
 submit a comment whose email or website metadata is rendered without sufficient attribute and URL encoding
 by listComments() in comments-bundle/contao/dca/tl_comments.php. When a backend user opens the Comments
 module, attacker-controlled script can execute in the Contao backend origin under that user's session.
 Unpublished comments remain visible to moderators, so moderation does not prevent exposure. This issue is
 fixed in versions 5.3.50 and 5.7.12. (CVE-2026-107845)

Solution

Update the contao/comments-bundle library and its related packages to version 5.3.50 or later.
