CVE-2022-50801Public exploitNetwork attack vector

Authenticated stored XSS via unsanitized URL filter

Published Dec 30, 2025 · Updated Dec 30, 2025

Stored XSS in JM-DATA Telekom JF511-TV 1.0.55, 1.0.62, and 1.0.67 allows remote authenticated users to run scripts. The /boaform/admin/formURL handler stores the url field for /secu_urlfilter_cfg_en.asp without neutralizing HTML or JavaScript. An authenticated account can plant code that runs in another user's browser when the URL-filter page is viewed, exposing that browser session to attacker-controlled actions.
