Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires two distinct preconditions: first, the attacker must have already compromised the Chrome renderer process on the victim's Android device (a significant prerequisite, typically requiring a separate sandbox-level vulnerability); second, the victim must actively interact with a crafted HTML page (UI:R). … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | All available signals converge on low real-world risk. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker who has already achieved renderer process compromise in Chrome for Android - for example via a separate memory corruption vulnerability in the browser's rendering engine - could serve a crafted HTML page that invokes the WebShare API with manipulated content. The malicious share dialog could be crafted to spoof a trusted application's sharing prompt, potentially tricking the user into sharing sensitive data with an unintended destination or taking an unintended action. … |
| Remediation | Update Google Chrome on Android to version 150.0.7871.47 or later; this is the vendor-confirmed patched release per the Chrome stable channel update advisory at http://chromereleases.googleblog.com/2026/06/stable-channel-update-for-desktop_0175352312.html. … Detailed patch versions, workarounds, and compensating controls in full report. |
