Plane is an open-source project management tool. Prior to 1.4.0, a user whose account has been deactivated by setting is_active=False can still log in with existing credentials. Successful authentication silently changes is_active back to True, reactivating the account without notifying the administrator. This issue is fixed in 1.4.0.

EchelonGraph scoreLOW confidence
This high-severity CVE scores 8.1 under a secondary CVSS source (NVD's own analysis pending). EPSS exploit-prediction score not yet available (the EPSS model rescores nightly; freshly-published CVEs typically appear within 48 hours). GitHub Security Advisory data not yet ingested — confidence will rise once GHSA publishes (typical lag: hours to days for open-source ecosystem CVEs; never for infrastructure-only CVEs).
