Vulnerable juju introspection abstract UNIX domain socket. An abstract UNIX domain socket responsible for introspection is available without authentication locally to network namespace users. This enables denial of service attacks.
An issue was discovered in Juju that resulted in the leak of the sensitive context ID, which allows a local unprivileged attacker to access other sensitive data or relation accessible to the local charm.
Juju before 1.25.12, 2.0.x before 2.0.4, and 2.1.x before 2.1.3 uses a UNIX domain socket without setting appropriate permissions, allowing privilege escalation by users on the system to root.
