CVE-2026-33677

Vikunja is an open-source self-hosted task management platform.

Published Mar 24, 2026 · updated Jun 17, 2026 · vikunja vikunja

Vikunja is an open-source self-hosted task management platform. Prior to version 2.2.1, the endpoint returns webhook BasicAuth credentials ( and ) in plaintext to any user with read access to the project. While the existing code correctly masks the HMAC field, the BasicAuth fields added in a later migration were not given the same treatment. This allows read-only collaborators to steal credentials intended for authenticating against external webhook receivers. Version 2.2.1 patches the issue.
