CVE-2023-34373Network attack vector

Plugin data deletion via forged privileged-user requests

Published Jun 19, 2023 · Updated Apr 28, 2026

CSRF in Dylan James Zephyr Project Manager 3.3.93 and earlier allows remote attackers to delete plugin data through forged requests. The advanced-settings action processes a state-changing deletion request without verifying that it originated from the logged-in user. A privileged WordPress user must visit attacker-controlled content, allowing the browser to submit the unwanted action with that user's session.
