Unauthenticated administrator takeover via customer role manipulation
Published Sep 2, 2026 · Updated Sep 2, 2026
Privilege escalation in Amelia 8.0 through 9.6.2 allows remote attackers to gain WordPress administrator access through its customer update endpoint. The endpoint insufficiently validates the attacker-controlled type value, permitting a customer role change to manager when externalId is 0 and creation of a wpamelia-manager user. No prior authentication is required; the manager role can then create a provider tied to an administrator user ID and overwrite that administrator's password.
