EPSS · scored 2026-10-27

Contao is an Open Source CMS. From version 4.0.0 until 5.3.50 and 5.7.12, ModuleSearch can disclose protected page titles, URLs, and indexed context snippets to unauthenticated visitors when contao.search.index_protected is changed from enabled to disabled. Authorization metadata is stored per row in tl_search, but disabling the setting removes the protected-row filter without deleting rows indexed while protection was enabled. The protected pages continue to return an authorization response, so this issue exposes search metadata and indexed text rather than bypassing page access. This issue is fixed in versions 5.3.50 and 5.7.12.

  • WID-SEC-W-2026-2999Contao: Mehrere SchwachstellenDeutsch2026-08-24csaf · cert_bundDE

    Ein Angreifer kann mehrere Schwachstellen in Contao ausnutzen, um Sicherheitsmaßnahmen zu umgehen, Berechtigungen zu erweitern und möglicherweise Administratorrechte zu erlangen, Cross-Site-Scripting-Angriffe durchzuführen, sensible Informationen offenzulegen und Daten zu manipulieren.

  • GHSA-x2rp-9qf7-2fmqContao: Protected page content is disclosed to anonymous visitors after contao.search.index_protected is disabled2026-10-09ghsa · osvUS

    `ModuleSearch` decides whether to filter protected pages out of search results based on the current value of `contao.search.index_protected`, but the authorisation data lives per row in `tl_search`. Turning the setting off removes the filter without removing the rows, so protected pages that were indexed while it was on are returned to unauthenticated visitors such as title, URL and context snippet, even though the pages themselves still answer 401. ## Impact Disclosure of member-only page titles, URLs and indexed text to unauthenticated visitors through the site search. The pages themselves remain access-controlled, so this is not a page-access bypass. ## Credits This security vulnerability was found by @iRevivalx .
