DescriptionCVE.org

Access of resource using incompatible type ('type confusion') in Microsoft Edge (Chromium-based) allows an unauthorized attacker to execute code over a network.

AnalysisAI

Remote code execution in Microsoft Edge (Chromium-based) stems from a type-confusion flaw (CWE-843) that an unauthenticated attacker can trigger when a victim visits a malicious web page. Microsoft has released an official fix, and while exploit maturity is currently unproven (no public exploit identified at time of analysis), the high confidentiality, integrity, and availability impact combined with network reach makes it a meaningful browser patch. The CVSS 3.1 base score is 7.5 with high attack complexity and required user interaction, tempering real-world exploitability.
