Notes
mdeslaur
The changes in the new version are massive and restrict configuration and data files to a specific directory set at build time. This may introduce a regression in stable releases depending on how existing installations are configured. On Debian and Ubuntu on noble+, the daemons are run as non-root, and are protected by AppArmor. These hardening measures mitigate this vulnerability. In addition, access to the RESTful API is restricted to authenticated users. AppArmor profile was introduced in (2.2.0-3) (noble+) RESTful API restriction was introduced in (2.2.0-8) (noble+)
