Nixpkgs
Monthly
Local privilege escalation to MySQL root in the NixOS services.mysql module (Nixpkgs, before the 25.11 and 26.05 channel fixes) lets any unprivileged local account - including web, CGI, or other service processes on the same host - authenticate as the database root@localhost user with no password when the module is deployed with the mysql or percona-server package. Because the module initialized root@localhost without socket or password authentication, the DBMS trusted any local connection as root, granting full read/write control over all databases. No public exploit code has been identified at time of analysis and it is not in CISA KEV, but exploitation is trivial for any local process meeting the precondition.
