Reflected XSS via unescaped GET parameter
Published Oct 4, 2021 · Updated Aug 3, 2024
Cross-site scripting in Better Find and Replace before 1.2.9 allows remote attackers to execute script in a victim’s browser via a crafted s parameter. The All Masking Rules page reflects the GET parameter without escaping it before rendering the response, so attacker-controlled markup executes in the browser when a victim follows the crafted link. Exploitation requires a victim to open that link; the record describes confidentiality and integrity impact in the browser context but no service interruption.
