Technical details
A server-side request forgery (SSRF) vulnerability exists in Microsoft Edge (Chromium-based browser) that permits an unauthorized attacker to perform spoofing over a network. The vulnerability allows an attacker to manipulate the browser into making requests to unintended destinations, potentially to internal network services or external third-party systems. This is typically exploited through malicious web pages or application logic that doesn't properly validate or sanitize user-controlled URLs. An attacker can exploit this via the network to bypass access controls and interact with restricted resources. Patches or mitigations should be available through Microsoft's security update channels.
