Inappropriate implementation in DevTools in Google Chrome prior to 150.0.7871.47 allowed an attacker who convinced a user to install a malicious extension to perform UI spoofing via a crafted Chrome Extension. (Chromium security severity: Low)
AnalysisAI
UI spoofing in Google Chrome's DevTools component allows an attacker to misrepresent critical interface information to users who have been socially engineered into installing a malicious Chrome Extension. Affected versions are all Chrome releases prior to 150.0.7871.47. The flaw stems from an inappropriate implementation (CWE-451) in DevTools, enabling an extension to manipulate how DevTools renders UI elements - potentially deceiving developers or power users into trusting falsified debugging output or security indicators. No public exploit code has been identified at time of analysis, and this vulnerability is not in the CISA KEV catalog.
Technical ContextAI
The vulnerability resides in Google Chrome's DevTools subsystem, the built-in browser developer toolset accessible via F12 or right-click inspect. CWE-451 (User Interface Misrepresentation of Critical Information) identifies the root cause as the DevTools UI failing to adequately isolate or validate rendering influence from Chrome Extensions, allowing extension-controlled content or UI artifacts to spoof legitimate DevTools panels or indicators. Chrome Extensions have defined permission scopes but the inappropriate implementation here permits a crafted extension to inject or manipulate DevTools UI elements beyond its intended boundary. Affected CPE covers Chrome versions below 150.0.7871.47 across desktop platforms as reported by EUVD.
RemediationAI
Update Google Chrome to version 150.0.7871.47 or later, which contains the vendor-released patch. The advisory is available at http://chromereleases.googleblog.com/2026/06/stable-channel-update-for-desktop_0175352312.html. Chrome auto-updates by default; administrators in managed enterprise environments should verify deployment via Google Admin Console or endpoint management tooling. As a compensating control prior to patching, organizations can enforce Chrome Extension allow-listing via enterprise policy (ExtensionInstallAllowlist / ExtensionInstallBlocklist) to prevent installation of unapproved extensions - this directly addresses the required attack precondition and has no meaningful trade-off for managed environments. Disabling DevTools access for non-developer user populations via the DeveloperToolsAvailability policy further limits exposure, though this impacts legitimate developer workflows.
