CVE-2026-34372

Sulu is an open-source PHP content management system based on the Symfony framework. Prior to 2.6.25 and 3.0.8, the affected Sulu 2.6 and 3.0 release lines have a Smart Content QueryBuilder in src/Sulu/Component/Content/SmartContent/QueryBuilder.php that concatenates category identifiers from the public categories query parameter into a JCR-SQL2 WHERE clause without numeric validation. On a public page containing a category-filtered Smart Content block, an unauthenticated attacker can alter query conditions to infer or enumerate content-repository nodes, including unpublished content, or submit malformed and expensive query fragments that degrade availability; this path does not modify repository data. This issue is fixed in versions 2.6.25 and 3.0.8.

Sulu, a PHP content management system, before versions 2.6.25 and 3.0.8 allows an attacker with media upload permission to store HTML, XHTML, or XML documents and create links with inline=1, causing the application to return the file without Content-Disposition attachment. Opening such a link by an authenticated user allows execution of malicious JavaScript in the context of the victim's session on the Sulu origin.

Sulu before versions 2.6.25 and 3.0.8 has a vulnerability in the media move endpoint where the permission check is based on the client-supplied collection value rather than the actual source collection. An authenticated backend user with edit permission in one collection can move an item out of a restricted collection and then view or download content they are not permitted to access.

Sulu before versions 2.6.25 and 3.0.8 does not enforce VIEW permission for target resources in the preview-link endpoint. An authenticated administrative user who knows a resource identifier can create or revoke a preview link for any page, article, or snippet, including content they cannot view. The generated preview URL is public and allows reading restricted content without authentication.

Sulu, an open-source PHP CMS based on Symfony, before versions 2.6.23 and 3.0.6 uses a weak cryptographic hash algorithm for password reset token and API key generation.
