Detailsinfo

A vulnerability was found in Sulu up to 2.6.24/3.0.7. It has been declared as problematic. This vulnerability affects the function PreviewLinkManager::generate/PreviewLinkManager::revoke of the file src/Sulu/Bundle/PreviewBundle/Application/Manager/PreviewLinkManager.php of the component Preview Link Manager.

As an impact it is known to affect confidentiality, integrity, and availability. CVE summarizes:

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.

The advisory is shared for download at github.com. This vulnerability was named CVE-2026-82394 since 08/29/2026. The exploitation appears to be easy. The attack can be initiated remotely. Additional levels of successful authentication are required for exploitation. Successful exploitation requires user interaction by the victim. There are known technical details, but no exploit is available. The MITRE ATT&CK project declares the attack technique as T1222.
