CVE-2025-11995Network attack vector

Unauthenticated stored XSS via event details

Published Nov 1, 2025 · Updated Nov 1, 2025

Stored XSS in Yannick Lefebvre Community Events 1.5.2 and earlier allows remote attackers to inject scripts through event details. The public event-submission path stores the event details parameter without sufficient sanitization, and event views render it without output escaping. No WordPress account is required; opening an injected event page executes the stored script in the visitor's browser, enabling page-content alteration and access to browser-readable data.
