CVE-2025-22635Network attack vector

Script execution via reflected unescaped input

Published Feb 23, 2025 · Updated May 12, 2026

Reflected XSS in imithemes Eventer before 3.9.9 allows remote attackers to execute scripts through crafted page requests. Eventer reflects request input into generated pages without sufficient sanitization or output escaping; public records do not identify the affected parameter or code locus. Exploitation is unauthenticated but requires a user to follow a crafted link, after which the script runs in that user's browser under the affected site's origin.
