CVE-2026-107842

Contao: Protected page content is disclosed to anonymous visitors after contao.search.index_protected is disabled

Published Oct 9, 2026 CVSS 3.1 · 5.3 Medium EPSS < 1% KEV · Not listed
Description
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.
