Home page URL: Security reports for WP Event Manager – Events Calendar, Registrations, Sell Tickets with WooCommerce
Application: WP Event Manager – Events Calendar, Registrations, Sell Tickets with WooCommerce
Published on: Nov 05, 2026
Research Description: The WP Event Manager WordPress plugin before 3.4.2 does not properly validate ownership or the type of the user-supplied post identifiers processed by one of its frontend forms, allowing any user with a Subscriber account or above to reassign the authorship of arbitrary posts to themselves and to force them to be published. This results in content takeover and in the public disclosure of otherwise private or draft content, and requires the relevant frontend feature to be enabled.
Affected versions: max 3.4.2.
Status: vulnerable
