CVE-2021-46780Public exploitNetwork attack vector

Administrator-session script execution via unescaped tab attribute

Published Apr 25, 2022 · Updated Aug 4, 2024

Reflected XSS in Supsystic Easy Google Maps before 1.9.32 allows remote attackers to execute script via a crafted tab parameter. The admin dashboard writes tab into an HTML attribute without output escaping, so a crafted value breaks the attribute boundary and installs an event handler. Exploitation requires an authenticated administrator to open the crafted admin URL; script then runs in that administrator's browser context.
