CVE-2026-92774: Wiki.js through 2.5.314 Authorization Bypass via GraphQL Tag Omission
Wiki.js through 2.5.314 omits page tags from authorization checks in multiple GraphQL resolvers, allowing tag-based access restrictions to be bypassed. Attackers can query the list, tree, tags, searchTags, and links resolvers to retrieve restricted page metadata including titles, descriptions, paths, and tag information without proper authorization.

Frequently Asked Questions
Who is realistically exposed to this issue?
Wiki.js deployments through 2.5.314 are affected where page access is restricted using tag-based rules and users can access the affected GraphQL functionality. The issue concerns metadata exposure through the list, tree, tags, searchTags, and links resolvers.
What does an attacker need to exploit it?
An attacker needs network access and a low-privileged account; no user interaction is required. The provided vector indicates that the attacker does not need elevated privileges.
What information can be exposed?
The affected resolvers can disclose restricted-page metadata, including titles, descriptions, paths, and tag information. The provided information does not state that page content can be retrieved through this issue.
How can I determine whether my deployment is affected?
Check whether the Wiki.js version is 2.5.314 or earlier and whether tag-based page access restrictions are in use. Also review whether lower-privileged users can issue the affected GraphQL queries.
