SCA: security update for contao/core-bundle (GHSA-q6wp-fr43-gm9v)

medium Tenable Cloud Security Plugin ID 474084

Description

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

 - Contao is an Open Source CMS. From version 5.7.1 until 5.7.12, core-bundle/config/services.yaml registers
 the preview access voter as Contao\CoreBundle\Security\Voter\DataContainer\PreviewAccessVoter although the
 shipped class is PreviewVoter. Symfony therefore omits voter autoconfiguration and removes the private
 service, so PreviewVoter::hasAccess() never enforces ownership. A non-admin backend user with the
 preview_link module can list every tl_preview_link record, obtain signed share URLs created by other
 users, and use them to view unpublished pages with showUnpublished despite lacking page permission. The
 advisory does not establish editing or deletion of foreign links. This issue is fixed in version 5.7.12.
 (CVE-2026-107850)

Solution

Update the contao/core-bundle library and its related packages to version 5.7.12 or later.
