Machine-written summary
Summary written by Claude Haiku from the source advisory. Not reviewed by a person.
Homer (github.com/sipcapture/homer-app), all versions before 0.0.0-20260625091610-b2e942031ff8, creates a default admin account with the hardcoded password "sipcapture" on fresh deployments that use internal authentication, and does not force a password change at first login. An attacker who can reach the login endpoint of such an instance can sign in as admin with full administrative access. Upgrade to 0.0.0-20260625091610-b2e942031ff8 or later, which contains the fix. Until upgrading, change the admin password on any existing deployment.
