Unauthenticated browser script execution via reflected input
Published Mar 17, 2024 · Updated Apr 28, 2026
Reflected XSS in Themeisle Visualizer 3.10.5 and earlier allows remote attackers to execute scripts in a visitor's browser. Public advisories do not identify the affected request parameter, handler, or the exact operation that reflects untrusted input without adequate output encoding. Exploitation requires user interaction with an attacker-crafted request; the resulting script executes in the affected site's origin and can read or alter accessible page data.
