Insufficient validation of untrusted input in WebAppInstalls in Google Chrome on Windows prior to 150.0.7871.47 allowed a remote attacker who convinced a user to engage in specific UI gestures to execute arbitrary code via a crafted HTML page. (Chromium security severity: High)
AnalysisAI
Remote code execution in Google Chrome on Windows before version 150.0.7871.47 allows an attacker to run arbitrary code by luring a victim to a crafted HTML page and getting them to perform specific UI gestures against the WebAppInstalls component. Chromium rates the flaw High severity; no public exploit identified at time of analysis, and the EPSS probability is low (0.26%, 17th percentile), indicating the attack is not yet broadly commoditized despite the serious impact.

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires the victim to be running Google Chrome on Windows at a version below 150.0.7871.47 and to visit an attacker-controlled crafted HTML page. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The signals are mixed and point to a genuine-but-conditional priority. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker hosts a crafted HTML page and social-engineers a Windows Chrome user (via phishing link or malvertising) into visiting it and performing the specific UI gestures the page prompts for, such as clicking through an install or permission dialog. The malformed input to the WebAppInstalls flow is then processed insufficiently, resulting in arbitrary code execution in the browser context. … |
| Remediation | Vendor-released patch: upgrade Google Chrome on Windows to 150.0.7871.47 or later via the Chrome Releases stable-channel update (https://chromereleases.googleblog.com/2026/06/stable-channel-update-for-desktop_0175352312.html); most environments should confirm auto-update completed and relaunch the browser to apply the fix, since Chrome updates only take effect after restart. … Detailed patch versions, workarounds, and compensating controls in full report. |
