CVE-2026-123502

MediumCVSS 5.2/10Last modified Nov 9, 2026

Description

Vikunja before 2.7.1 contains an information exposure vulnerability that allows log readers to obtain link-share hashes because the request logger records the raw URI of the /shares/:share/auth route. Attackers with access to Vikunja or reverse proxy access logs can reuse non-expiring, non-password-protected share hashes to obtain a project JWT with read, write or admin permission.
