CVE-2025-7920Network attack vector

Browser script execution via undisclosed input reflection

Published Jul 21, 2025 · Updated Jul 21, 2025

Reflected XSS in Simopro Technology WinMatrix3 Web package 1.2.39.5 and earlier allows remote attackers to execute JavaScript via phishing. TWCERT/CC and Simopro Technology have not published the affected route or parameter, so the precise reflection and output-encoding failure remain undisclosed. Exploitation requires no authentication but does require a user to open a crafted phishing link, after which script runs in that user's browser context.
