Description

PowerDNS-Admin through 2026.08.1 contains an authorization bypass vulnerability that allows authenticated User-role accounts to refresh secondary zones they cannot access by supplying a different 'domain' field in the JSON body. Attackers authorized for any one zone can force axfr-retrieve transfers of other users' secondary zones and infer zone existence from differing responses.
