Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation targets the WebAppInstalls (web app / PWA installation) component of Chrome on Android and requires the victim to load an attacker-crafted HTML page, so in practice the user must navigate to attacker-controlled content - a limiting factor the vendor's UI:N rating omits. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The signals conflict and warrant scrutiny. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker crafts a malicious HTML page and lures an Android Chrome user to open it (for example via a phishing link or malvertising). The page abuses the insufficiently validated WebAppInstalls flow to bypass discretionary access controls, letting the attacker influence integrity-sensitive state or app-permission decisions on the device. … |
| Remediation | Vendor-released patch: update Google Chrome for Android to 150.0.7871.47 or later, per the Chrome Releases advisory (https://chromereleases.googleblog.com/2026/06/stable-channel-update-for-desktop_0175352312.html). … Detailed patch versions, workarounds, and compensating controls in full report. |
