Incorrect authorization in WebView in Google Chrome on on Android prior to 153.0.8010.36 allowed a remote attacker who had compromised the renderer process to potentially execute arbitrary code outside the sandbox via a crafted HTML page. (Chromium security severity: Medium)
AnalysisAI
Sandbox escape via incorrect authorization in the WebView component of Google Chrome on Android (prior to 153.0.8010.36) allows a network-based attacker to execute arbitrary code outside the Chrome renderer sandbox. Exploitation is a two-stage process: the attacker must first compromise the renderer process, then leverage the CWE-863 authorization flaw in WebView to break out of the sandbox via a crafted HTML page. …

Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires two distinct conditions: (1) the attacker must first compromise the Chrome renderer process on the target Android device - this is an explicit prerequisite stated in the description, representing a separate vulnerability or exploit chain step; (2) the victim must visit a crafted HTML page in Google Chrome on Android, satisfying the UI:R user-interaction requirement. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 3.1 vector AV:N/AC:H/PR:N/UI:R/S:C/C:H/I:H/A:H yields a score of 8.3, but this figure warrants contextual adjustment. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
