Server-side request forgery (ssrf) in Microsoft Edge (Chromium-based) allows an unauthorized attacker to perform spoofing over a network.
AnalysisAI
Server-side request forgery in Microsoft Edge (Chromium-based) lets a remote, unauthenticated attacker coax a victim's browser into issuing forged network requests, enabling spoofing and disclosure of sensitive data over the network. Exploitation requires user interaction (visiting or interacting with attacker-controlled content), and the CVSS scope-change flag indicates the browser can be pivoted to reach resources beyond its own security boundary. No public exploit identified at time of analysis (CVSS E:U), but a vendor fix is already available and the finding is vendor-confirmed (RC:C).
Technical ContextAI
The affected component is the Chromium-based Microsoft Edge browser (cpe:2.3:a:microsoft:microsoft_edge_(chromium-based)). The root cause class is CWE-918 (Server-Side Request Forgery): the browser can be induced to make requests to a destination chosen or influenced by an attacker, without adequately validating or restricting the target. In a browser context, SSRF-style flaws typically stem from the rendering/networking layer following attacker-controlled URLs, redirects, or resource references, allowing requests to be directed at internal or otherwise unintended endpoints. The CVSS scope-change (S:C) reflects that the impact crosses the browser's own trust boundary - the compromised component (Edge) is used to reach a different security authority (e.g., internal network resources).
RemediationAI
Patch available per vendor advisory: update Microsoft Edge to the fixed build documented at https://msrc.microsoft.com/update-guide/vulnerability/CVE-2026-57993 (RL:O confirms an official remediation exists); the input does not specify an exact fixed version number, so confirm the target build from the MSRC page before deployment. Because Edge auto-updates by default, ensure the browser's automatic update mechanism is enabled and not blocked by group policy, and force-restart Edge on managed endpoints to apply the update. As a compensating control until patched, restrict browsing of untrusted sites and enforce network egress/segmentation so that browser-originated requests cannot reach sensitive internal endpoints (SSRF targets) - with the trade-off that aggressive egress filtering can break legitimate internal web applications and should be scoped to sensitive segments.
