Summary

Duplicate Advisory: Vikunja: API token scopes bypassed via task expand parameter (comments, reactions, time entry counts)

Details

Duplicate Advisory

This advisory has been withdrawn because it is a duplicate of GHSA-9rg3-v78m-26q8. This link is maintained to preserve external references.

Original Description

Vikunja before 2.6.0 contains an API token scope bypass vulnerability in task read endpoints where authorization fails to inspect query string parameters. Attackers with limited token scopes can use the expand parameter to access restricted data like comments, reactions, and time entries without proper permission verification.
