March 18, 2026 (updated March 25, 2026)

Low-privileged Control Panel users could create taxonomy terms by submitting requests to the field action processing endpoint with attacker-controlled field definitions. This bypasses the authorization checks enforced on the standard taxonomy term creation endpoint.
