The vendor confirms: "The reported tab/entity-based URL bypass is covered by our previously implemented SVG security hardening. The fix replaces the blacklist-based checks with namespace-aware element and attribute allowlists, restricts permitted references to document-local fragments, and applies a restrictive Content Security Policy to uploaded SVG responses.

Vikunja from 2.4.0 before 2.7.1 contains an authentication bypass vulnerability that allows disabled or locked users to retain access through API tokens owned by their bot users.
