Answer in brief
CVE-2026-71274 records a High severity (CVSS 8.5) vulnerability in OpenBK7231T Stored XSS via Unsanitized MQTT-Set Channel Labels. The current sources do not mark it as known exploited. The current feed maps openshwprojects/OpenBK7231T_App (generic). Check affected ranges and fixed versions before updating.
Analysis pending evidence review
HOL Guard separates source facts from reviewed analysis. See the methodology.
CVSS is 8.5. The current sources do not mark it as known exploited. Treat this as a source-backed prioritization signal, not a statement about your environment.

OpenBK7231T's CHANNEL_SetLabel() (src/cmnds/cmd_channels.c) stores channel labels received via the MQTT SetChannelLabel command using strdup() with no HTML sanitization. CHANNEL_GetLabel() returns these labels unsanitized, and they are rendered via hprintf255() at 15+ locations in src/httpserver/http_fns.c with no HTML encoding. An attacker with MQTT broker access (commonly unauthenticated in real deployments) can set a channel label containing a <script> payload that executes when any user views the device's web panel.
