Summary
Cross-site scripting in OpenBK7231T (CVE-2026-71275). Risk of unauthorized operations or information disclosure. Exploitable via host.
Original description
The description as published by the source.
OpenBK7231T's http_fn_ota_exec() (src/httpserver/http_fns.c) reflects the host query parameter directly into an HTML response via hprintf255(request, "OTA requested for %s!", tmpA) with no HTML encoding, allowing a crafted URL such as /ota_exec?host=alert(1) to execute JavaScript in an authenticated admin's browser when they click a malicious link.
