CVE-2026-82394
MediumCVSS 5.3Summary
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.
Risk Assessment
An attacker can access confidential content without authorization and share it with others, leading to data confidentiality breaches.
Recommendation
Update Sulu to version 2.6.25 or 3.0.8, which introduce proper permission checks for preview links.
Other vulnerabilities in Sulu
See all- CVE-2026-82396Medium
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.
- CVE-2026-82395Medium
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.
- CVE-2026-45701Medium
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.
- CVE-2026-34372Low
In Sulu, an open-source PHP CMS based on Symfony, versions 1.0.0 through 2.6.22 and 3.0.0 through 3.0.5, a user with permission for the Sulu Admin via at least one role could access sub-entities of contacts via the admin API without having permission for contacts.
Original NVD description (English source)
Sulu is an open-source PHP content management system based on the Symfony framework. Prior to versions 2.6.25 and 3.0.8, the preview-link endpoint and src/Sulu/Bundle/PreviewBundle/Application/Manager/PreviewLinkManager.php do not enforce VIEW permission for the target resource in PreviewLinkManager::generate() or PreviewLinkManager::revoke(). An authenticated administration user who knows a target resource identifier can create or revoke a preview link for any page, article, or snippet, including content in a webspace or area the user cannot view. A generated preview URL is public and resolves content by an opaque token, allowing the user or anyone receiving the link to read restricted content without authentication. This issue is fixed in versions 2.6.25 and 3.0.8.
