CVE-2026-14819
What is CVE-2026-14819?
The Event Tickets and Registration plugin for WordPress, prior to version 5.28.4, has a vulnerability where event titles are not appropriately sanitized before being logged in the ticket history. This oversight allows users with the Editor role or above to execute Stored Cross-Site Scripting attacks. Such exploits could potentially affect higher-privileged users, especially in multisite installations, leading to unauthorized actions within the application. Proper input validation and output escaping mechanisms are crucial to mitigate these risks.
