CVE-2022-2654Public exploitNetwork attack vector

Reflected XSS via unescaped search attribute

Published Sep 16, 2022 · Updated Jun 5, 2025

Reflected XSS in RadiusTheme Classima before 2.1.11 and four required plugins allows remote attackers to run script in a user's browser. The all-ads search page writes the q parameter into the Search field's HTML attributes without escaping, so attacker-supplied event-handler markup enters the response. The attack requires a user to open a crafted URL and move the pointer over the Search field; affected plugins are Classified Listing before 2.2.14, Classified Listing Pro before 2.0.20, Store & Membership before 1.4.20, and Classima Core before 1.10.
