Microsoft lists Edge versions before 149.0.4022.62 as affected, but its release notes say a security fix is still being prepared. Microsoft marks the flaw as not exploited.

Microsoft published CVE-2026-62765 on Oct. 27, describing a type-confusion flaw (CWE-843) in Microsoft Edge (Chromium-based) that "allows an unauthorized attacker to execute code over a network." Microsoft rates it Important with a CVSS 3.1 base score of 7.5 (High); the vector lists high attack complexity and required user interaction.
An unauthorized attacker can exploit the issue over a network to execute arbitrary code.
Microsoft's Security Update Guide marks the bug as not exploited and not publicly disclosed, with an exploitability assessment of "Exploitation Less Likely." It does not appear in CISA's Known Exploited Vulnerabilities catalog, and Google's Oct. 27 Chrome 156 security list does not mention it.

The patch status is unclear. The advisory and the NVD record list Edge versions before 149.0.4022.62 as affected, but that build dates to June, and Edge's security release notes on Oct. 27 say only that Microsoft is "actively working on releasing a security fix." Microsoft has not published a fixed build for current Stable releases; users should keep Edge updated and watch Microsoft's advisory for a revision.
