CVE-2025-9894Network attack vector

Unauthorized synchronization via missing nonce validation

Published Sep 27, 2025 · Updated Sep 27, 2025

Cross-site request forgery in Sync Feedly 1.0.1 and earlier allows remote attackers to trigger Feedly content synchronization. The crsf_cron_job_func function processes synchronization requests without validating a WordPress nonce. Exploitation requires a site administrator to act on a forged request; the result is an unauthorized synchronization run, with post creation dependent on available Feedly content.
