Authenticated script execution via undisclosed DOM sink
Published Jan 5, 2026 · Updated Jan 5, 2026
DOM-based XSS in INFINITUM FORM Geo Controller 8.5.2 and earlier allows remote authenticated users to execute script in a victim's browser. Patchstack has not published the client-side source, DOM sink, or untrusted input that triggers the script execution. Exploitation requires low-privileged access and user interaction; successful script runs in the victim site's browser context and can read or alter accessible page data.
