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.

The precondition is that the user's account was previously deactivated by setting is_active=False.","blast_radius":"If exploited, this could lead to unauthorized access to project management tools and sensitive information, impacting multiple users and projects.","remediation":"Upgrade to version 1.4.0 or later.","detection":"No reliable host or network indicator is derivable from the published description.","tags":["auth-bypass","web","project-management"],"model":"qwen2.5:7b-instruct","analyzedAt":"2026-10-06T08:45:35.854Z"}}
