CVE-2026-92776

Wiki.js through 2.5.314 fails to require path separators when matching START and END page rules, allowing attackers to access pages sharing a prefix with authorized folders. Users granted access to a folder can read and modify unrelated pages with matching prefixes, bypassing intended access controls.
