Fleet has an Access Control vulnerability in debug/pprof endpoints

Fleet is open source device management software. A broken access control issue in versions prior to 4.78.3, 4.77.1, 4.76.2, 4.75.2, and 4.53.3 allowed authenticated users to access debug and profiling endpoints regardless of role. As a result, low-privilege users could view internal server diagnostics and trigger resource-intensive profiling operations. Fleet’s debug/pprof endpoints are accessible to any authenticated user regardless of role, including the lowest-privilege “Observer” role. This allows low-privilege users to access sensitive server internals, including runtime profiling data and in-memory application state, and to trigger CPU-intensive profiling operations that could lead to denial of service. Versions 4.78.3, 4.77.1, 4.76.2, 4.75.2, and 4.53.3 fix the issue. If an immediate upgrade is not possible, users should put the debug/pprof endpoints behind an IP allowlist as a workaround.

Fleet: Unauthenticated Android device disenrollment vulnerability via Pub/Sub endpoint

Fleet is open source device management software. In versions prior to 4.80.1, a vulnerability in Fleet’s Android MDM Pub/Sub handling could allow unauthenticated requests to trigger device unenrollment events. This may result in unauthorized removal of individual Android devices from Fleet management. If Android MDM is enabled, an attacker could send a crafted request to the Android Pub/Sub endpoint to unenroll a targeted Android device from Fleet without authentication. This issue does not grant access to Fleet, allow execution of commands, or provide visibility into device data. Impact is limited to disruption of Android device management for the affected device. Version 4.80.1 fixes the issue. If an immediate upgrade is not possible, affected Fleet users should temporarily disable Android MDM.

The Feather Login Page plugin for WordPress is vulnerable to unauthorized access of data due to a missing capability check on the 'getListOfUsers' function in versions starting from 1.0.7 up to, and including, 1.1.1. This makes it possible for authenticated attackers, with subscriber-level permissions and above, to access the login links, which can be used for privilege escalation.
