Browser script execution via reflected search input

Published Jun 16, 2025 · Updated Jun 16, 2025

Reflected XSS in all versions of Phoenix BV Phoenix CMS allows remote attackers to execute script in a user's browser via /search. The endpoint reflects the untrusted s GET parameter into the generated search page without sufficient output neutralization, causing crafted script content to execute when the page is rendered. Exploitation requires a user to interact with the crafted request; the script runs in that user's browser context and can read or alter page-accessible data.
