{"id":"CVE-2026-105641","published":"2026-10-05T19:17:18.560","lastModified":"2026-10-07T22:17:02.170","description":"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.","cvssScore":9.8,"cvssSeverity":"CRITICAL","cvssVector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","cwes":["CWE-798"],"vendors":[],"products":[],"references":[{"url":"https://github.com/makeplane/plane/commit/1acc69e816a9a8789032bf711aa9a3c12fcd285c","tags":[]},{"url":"https://github.com/makeplane/plane/pull/9291","tags":[]},{"url":"https://github.com/makeplane/plane/releases/tag/v1.4.0","tags":[]},{"url":"https://github.com/makeplane/plane/security/advisories/GHSA-cmwv-pjmw-8483","tags":[]}],"exploitRefs":[{"url":"https://github.com/makeplane/plane/commit/1acc69e816a9a8789032bf711aa9a3c12fcd285c","tags":[]},{"url":"https://github.com/makeplane/plane/pull/9291","tags":[]},{"url":"https://github.com/makeplane/plane/releases/tag/v1.4.0","tags":[]},{"url":"https://github.com/makeplane/plane/security/advisories/GHSA-cmwv-pjmw-8483","tags":[]}],"hasPoc":true,"ai":{"summary":"The flaw lies in the default SECRET_KEY and LIVE_SERVER_SECRET_KEY values in Plane project management tool versions prior to 1.4.0, allowing attackers to forge signed values and bypass authentication.","exploitability":"Exploitation is relatively straightforward if the default keys are not changed, requiring knowledge of the hardcoded values.","blast_radius":"If exploited, attackers could compromise user accounts and sessions, leading to significant data breaches and loss of confidentiality.","remediation":"Upgrade to Plane version 1.4.0 or later.","detection":"No reliable host or network indicator is derivable from the published description.","tags":["auth-bypass","web","config-flaw"],"model":"qwen2.5:7b-instruct","analyzedAt":"2026-10-06T08:44:34.768Z"}}
