Insufficient validation of untrusted input in WebAppInstalls in Google Chrome on Android prior to 150.0.7871.47 allowed a local attacker to potentially perform a sandbox escape via a malicious file. (Chromium security severity: Medium)
AnalysisAI
Sandbox escape in Google Chrome for Android before 150.0.7871.47 lets a local attacker break out of the renderer/browser sandbox by feeding a malicious file into the WebAppInstalls component, which insufficiently validates untrusted input (CWE-20). Chromium rates the security severity as Medium, and no public exploit has been identified at time of analysis; EPSS estimates only a 0.13% (3rd percentile) chance of exploitation in the next 30 days. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires a locally delivered malicious file that is processed by the WebAppInstalls (web app / PWA installation) component of Chrome on Android - this is the exact feature that must be exercised. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The signals conflict and should be reconciled before prioritization. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker delivers a crafted file to a victim's Android device (for example via a download, messaging app, or shared storage) and induces Chrome's WebAppInstalls flow to process it. The malformed input bypasses input validation and lets the attacker escape Chrome's sandbox, gaining influence over resources outside the browser's isolation boundary. … |
| Remediation | Vendor-released patch: update Google Chrome on Android to 150.0.7871.47 or later via Google Play or Chrome's built-in updater, then restart the browser to complete the update; this is the primary and sufficient fix. … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
Within 24 hours: Inventory all Android devices running Chrome before version 150.0.7871.47 using mobile device management (MDM) or enterprise inventory tools. …
