CVE-2026-123505 Details
Description
Vikunja before 2.7.1 contains an insecure file permissions vulnerability that allows local users to read stored data because localStorage.Write creates blobs world-readable. Local attackers on a shared host can read attachments, project backgrounds and exports, and copy the SQLite database to crack password hashes offline.
A vulnerability in Vikunja versions prior to 2.7.1 allows local users to read sensitive stored data due to insecure file permissions. The issue arises because the 'localStorage.Write' function creates blobs that are world-readable. On shared hosting environments, this vulnerability enables local attackers to access attachments, project backgrounds, exports, and the SQLite database of other users, including password hashes, which could be exploited for offline cracking.
Users can update to Vikunja version 2.7.1 or later, where this vulnerability has been patched.
