CVE-2025-14160Network attack vector

API key modification via nonce-free settings update

Published Dec 12, 2025 · Updated Dec 12, 2025

Cross-site request forgery in Upcoming for Calendly 1.2.4 and earlier allows remote attackers to change the Calendly API key. The settings form accepts and stores a submitted access token without verifying a WordPress nonce, allowing a cross-origin request to overwrite the saved credential. A site administrator must be logged in and induced to open the attacker’s link; the consequence is limited to modifying the plugin’s Calendly credential, with no broader WordPress control reported.
