CVE-2025-60711 Overview
CVE-2025-60711 is a protection mechanism failure vulnerability in Microsoft Edge (Chromium-based) that allows an unauthorized attacker to execute code over a network. The flaw is categorized under [CWE-693: Protection Mechanism Failure] and requires user interaction to exploit. An attacker must convince a user to interact with crafted web content to trigger the weakness.
Microsoft assigned this vulnerability a CVSS 3.1 base score of 6.3, reflecting limited impact on confidentiality, integrity, and availability. The exploit prediction score (EPSS) is 0.375% at the 29.6 percentile, indicating a low observed exploitation probability at the time of publication.
Critical Impact
A remote attacker can execute code within the browser context after a user interacts with attacker-controlled content, bypassing a browser protection mechanism.
Affected Products
- Microsoft Edge (Chromium-based) — all versions prior to the fixed release referenced in the Microsoft Security Response Center (MSRC) advisory
- Windows installations running vulnerable Microsoft Edge builds
- macOS installations running vulnerable Microsoft Edge builds
Discovery Timeline

Technical Details for CVE-2025-60711
Vulnerability Analysis
The vulnerability originates in a browser protection mechanism within Microsoft Edge (Chromium-based) that fails to enforce its intended security boundary. When the protection fails, attacker-supplied content processed by the browser can trigger code execution over the network. The flaw maps to [CWE-693], which covers cases where a security control exists but does not function as designed.
Exploitation requires user interaction, such as visiting a crafted web page or clicking a malicious link. No prior authentication is required. The impact scope remains within the affected browser process, and the CVSS metrics indicate low impact to confidentiality, integrity, and availability rather than full system compromise.
Root Cause
The root cause is a failed protection mechanism inside the Chromium-based Edge browser. Microsoft's advisory categorizes the issue as a bypass of a built-in defense that should have blocked the attacker's code path. The specific component and fault location are not disclosed in the public advisory beyond the CWE classification.
Attack Vector
The attack vector is network-based with low attack complexity. An attacker hosts crafted content on a web server or delivers it through a phishing link. When a targeted user opens the content in a vulnerable version of Microsoft Edge, the protection mechanism fails and attacker-controlled code executes within the browser context. Full technical exploitation details are not published; refer to the Microsoft Security Update CVE-2025-60711 advisory for vendor guidance.
Detection Methods for CVE-2025-60711
Indicators of Compromise
- Unexpected child processes spawned by msedge.exe, particularly command interpreters such as cmd.exe, powershell.exe, or scripting hosts
- Outbound network connections from Edge browser processes to newly registered or low-reputation domains following user web activity
- Browser crash dumps or renderer process terminations correlated with visits to untrusted sites
Detection Strategies
- Monitor endpoint telemetry for anomalous process trees where Microsoft Edge launches non-browser executables or scripting engines
- Correlate browser navigation events with subsequent file writes to user-writable directories such as %TEMP% or %APPDATA%
- Deploy behavioral analytics that flag deviations from normal Edge process behavior on managed endpoints
Monitoring Recommendations
- Ingest browser and endpoint process logs into a centralized data lake for cross-host correlation and retrospective hunting
- Track Microsoft Edge version inventory across the fleet to identify hosts still running vulnerable builds
- Alert on high-privilege user accounts that browse to uncategorized or newly seen domains from managed devices
How to Mitigate CVE-2025-60711
Immediate Actions Required
- Update Microsoft Edge (Chromium-based) to the fixed version listed in the Microsoft Security Update CVE-2025-60711 advisory
- Verify automatic browser updates are enabled and enforced through group policy on all managed endpoints
- Restrict browsing to untrusted sites from privileged workstations until patching is confirmed
Patch Information
Microsoft has published a security update for this vulnerability. Administrators should consult the Microsoft Security Update CVE-2025-60711 advisory for the specific fixed build number and deployment guidance. Patch deployment should be validated by checking the installed Edge version through edge://settings/help.
Workarounds
- Enforce user awareness training so users avoid interacting with unsolicited links, since exploitation requires user interaction
- Apply network-layer web filtering to block access to known malicious and uncategorized domains
- Use application control policies to prevent Microsoft Edge from spawning scripting hosts or command shells
# Verify installed Microsoft Edge version on Windows
reg query "HKLM\SOFTWARE\Microsoft\Edge\BLBeacon" /v version
# Enforce automatic updates via Group Policy registry key
reg add "HKLM\SOFTWARE\Policies\Microsoft\EdgeUpdate" /v UpdateDefault /t REG_DWORD /d 1 /f
