What is CVE-2026-92774?

Wiki.js versions prior to 2.5.314 present a significant flaw where page tags are not subjected to authorization checks within various GraphQL resolvers. This oversight permits attackers to bypass access restrictions based on tags, enabling unauthorized retrieval of sensitive page metadata such as titles, descriptions, paths, and tag details. The exploit targets multiple resolvers, including list, tree, tags, searchTags, and links, jeopardizing the integrity of information contained within restricted pages.

Affected Version(s)

Wiki.js 0 <= 2.5.314

Exploit Proof of Concept (PoC)

PoC code is written by security researchers to demonstrate the vulnerability can be exploited. PoC code is also a key component for weaponization which could lead to ransomware.
