Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

Homer (github.com/sipcapture/homer-app) is vulnerable in versions before 0.0.0-20260625093330-5e90809657c9, which is the fixed version. When the JWT secret is left empty, which is the default, the JWT middleware skips authentication, so an unauthenticated attacker with network access can reach protected API endpoints. They could then read and change configuration, users, database connections, and stored call data. Upgrade to 0.0.0-20260625093330-5e90809657c9 or later, and set a strong coordinator JWT secret in the meantime.
