CVE-2025-11925Network attack vector

Browser script execution via wrong Content-Type

Published Oct 17, 2025 · Updated Oct 17, 2025

Cross-site scripting in Azure Access Technology BLU-IC2 and BLU-IC4 1.19.5 and earlier allows remote attackers to inject HTML or JavaScript. The affected API labels a JSON reply as text/html, causing browsers to interpret attacker-influenced response content as executable markup rather than data. The vendor has not disclosed the endpoint, attacker-controlled field, or whether a victim must open crafted content; execution occurs in the API origin.
