OpenProject manages project data, documents, meetings, and user sessions. Security posture depends on fast patch adoption and strict controls around authentication, host headers, and attachment processing.
¶ 1) Track and apply security releases quickly
- Follow OpenProject security advisories and release notes continuously.
- Prioritize updates for versions with published CVEs (e.g., 16.6.2, 16.6.3, 16.6.4, 16.6.5 and newer).
- Keep within supported release branches.
- Validate upgrades in staging before production rollout.
¶ 2) Harden ingress, host header, and session controls
- Enforce strict host header validation behind reverse proxy.
- Configure trusted proxy headers correctly and deny arbitrary
X-Forwarded-Host input.
- Restrict session administration endpoints and monitor anomalous session deletion behavior.
- Enforce SSO + MFA for admin users.
¶ 3) Protect attachment and export workflows
- Restrict upload types and disable risky image coders where possible.
- Keep PDF/export processing dependencies patched.
- Restrict who can access meeting/project exports.
- Encrypt backups containing work packages, comments, and attachments.
