CVE-2025-5084Public exploitNetwork attack vector

Reflected XSS via unescaped read-more text

Published Jul 24, 2025 · Updated Apr 8, 2026

Reflected XSS in AddonMaster Post Grid Master 3.4.13 and earlier allows remote attackers to execute scripts through a crafted AJAX request. The asr_filter_posts AJAX action accepts argsArray['read_more_text'] and returns it in generated grid markup without sufficient sanitization or output escaping. Exploitation requires a user to submit the crafted request, after which the script runs in that user's browser context.
