CVE-2022-25303Public exploitNetwork attack vector

Reflected XSS via unescaped error message

Published Jul 12, 2022 · Updated Sep 16, 2024

Reflected XSS in Whoogle Search before 0.7.2 allows remote attackers to execute script in a user's browser through the q query parameter. The /url route builds error_message from q values lacking the string http, and error.html applies Jinja's safe filter so the value is not escaped. Exploitation requires a user to open the crafted URL; script runs in the Whoogle origin and can read or modify browser-accessible data.
