Typography settings modification via missing nonce validation

Published Sep 11, 2025 · Updated Apr 8, 2026

CSRF in the Zoho Flow WordPress plugin 2.14.1 and earlier allows remote attackers to modify typography settings via a forged request. The zoho_flow_deactivate_plugin function accepts a state-changing request without correctly validating a WordPress nonce. Exploitation requires an administrator with an authenticated WordPress session to interact with attacker-controlled content; the reported effect is limited to typography-setting modification.
