Microsoft Edge Elevation of Privilege Flaws Tracked Across Multiple CVEs

Microsoft has published Security Update Guide entries for multiple Microsoft Edge (Chromium-based) elevation of privilege vulnerabilities, including CVE-2022-30127, CVE-2023-36027, and CVE-2024-21388. The advisories indicate that separate privilege-escalation issues have been identified in the browser across multiple release cycles, reinforcing Edge as a recurring target for flaws that could allow an attacker to gain higher privileges on an affected system.

While the referenced advisories provide limited public technical detail, the affected product and vulnerability class are consistent across all entries: Elevation of Privilege in Chromium-based Edge. Organizations using Microsoft Edge should review the corresponding Security Update Guide records, verify that browser updates have been applied across endpoints, and prioritize remediation because privilege-escalation bugs can increase the impact of other compromises by helping attackers move from initial code execution or user-level access to more powerful system permissions.
