CVE-2025-13684Network attack vector

Settings modification via missing nonce validation

Published Dec 5, 2025 · Updated Apr 8, 2026

Cross-site request forgery in ARK Related Posts 2.19 and earlier allows remote attackers to modify plugin settings through an administrator's browser. The ark_rp_options_page function accepts configuration changes without validating a WordPress nonce, so a forged request inherits the administrator's active session. Exploitation requires an administrator to open attacker-controlled content, and the documented consequence is limited to plugin configuration changes.
