Improper authorization in Microsoft Edge (Chromium-based) allows an unauthorized attacker to bypass a security feature over a network.
AnalysisAI
Security-feature bypass in Microsoft Edge (Chromium-based) versions prior to 150.0.4078.48 lets a remote, unauthenticated attacker circumvent a browser security control over the network via improper authorization (CWE-285). Microsoft rates it CVSS 10.0 with a changed scope, meaning a successful bypass can affect resources beyond the browser's original security boundary. …
