Browser script execution via unescaped AJAX parameter
Published Apr 24, 2023 · Updated Feb 4, 2025
Reflected XSS in WPDreams Ajax Search Lite before 4.11.1 and Ajax Search Pro before 4.26.2 allows remote attackers to run browser scripts. The wd_search_cf AJAX action processes an encoded wd_args delimiter and returns the attacker-controlled value without sanitizing or escaping it. Exploitation requires a high-privilege user, such as an administrator, to submit a crafted request; successful execution occurs in that user's browser context.
