Every CVE for makeplane plane

Exploited in the last 30 days

Plane is an open-source project management tool. Prior to 1.4.0, the deployments/aio/community/ and deployments/cli/community/ manifests provide fixed, publicly known SECRET_KEY and LIVE_SERVER_SECRET_KEY defaults that remain active when operators do not override them. The top-level setup.sh randomizes secrets only for the development Docker Compose path, leaving unchanged aio and cli community deployments with shared production secrets. Knowledge of SECRET_KEY enables attackers to forge Django-signed values and compromise accounts or sessions. Knowledge of LIVE_SERVER_SECRET_KEY bypasses live-service authentication on unchanged community deployments. This issue is fixed in 1.4.0.
