Unauthenticated privileged account creation via unbound invitation tokens
Published Dec 28, 2022 · Updated Apr 11, 2025
Improper access control in authentik before 2022.10.4 and 2022.11.0 through 2022.11.3 allows remote attackers to create privileged accounts. Invitation URL validation accepts a valid token after the enrollment-flow slug is changed because the token is not bound to its configured flow. Exploitation requires invitations, multiple enrollment flows granting different permissions, and knowledge or discovery of another flow slug; the default configuration is unaffected.
