CVE-2026-33312: Vikunja

Medium severity, CVSS 5.4. EPSS: 0.3% chance of exploitation in the next 30 days.

Vikunja is an open-source self-hosted task management platform. Starting in version 0.20.2 and prior to version 2.2.0, the `DELETE /api/v1/projects/:project/background` endpoint checks `CanRead` permission instead of `CanUpdate`, allowing any user with read-only access to a project to permanently delete its background image. Version 2.2.0 fixes the issue.

Affected products

• Vikunja Vikunja: from 0.20.2, before 2.2.0 (fixed in 2.2.0)
