CVE-2025-34114Network attack vector

Client-side attacks via missing security headers

Published Jul 25, 2025 · Updated Jul 28, 2025

Security misconfiguration in Laser Romae OpenBlow allows remote attackers to expose users to client-side attacks via missing HTTP headers. The web application's HTTP response handler omits CSP, Referrer-Policy, Permissions-Policy, COEP, and CORP, while some deployments place CSP in an HTML meta element that cannot enforce every directive. Exploitation requires user interaction with attacker-controlled content and enables script injection, framing attacks, or referer leakage; no direct service interruption is reported.
