Inappropriate implementation in Network in Google Chrome on Android prior to 150.0.7871.47 allowed a remote attacker who had compromised the renderer process to bypass site isolation via a crafted HTML page. (Chromium security severity: Medium)
AnalysisAI
Site isolation bypass in Google Chrome on Android prior to 150.0.7871.47 enables a remote attacker - who has already achieved renderer process compromise via a separate exploit - to break cross-origin security boundaries using a crafted HTML page. The root cause is CWE-346 (Origin Validation Error) in Chrome's Android-specific network implementation, meaning the network layer fails to enforce origin checks when requests originate from a compromised renderer context. …

Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires two sequential conditions: (1) the attacker must have already achieved code execution within the Chrome renderer process on Android via a separate, independent vulnerability - this is a hard prerequisite explicitly stated in the CVE description and is not fulfilled by this CVE alone; (2) the victim must visit or be redirected to a crafted HTML page (UI:R), triggering the network implementation flaw from within the compromised renderer context. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The official CVSS 3.1 vector (AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:H/A:N, score 6.5) materially understates attack complexity: it assigns AC:L despite the description explicitly requiring a prior renderer process compromise, which is a significant prerequisite not reflected in the score. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker first exploits a separate renderer process vulnerability (e.g., a V8 JavaScript engine bug) to gain code execution inside Chrome's renderer sandbox on an Android device. They then navigate the victim to a crafted HTML page that triggers the Android-specific network implementation flaw, breaking site isolation to perform unauthorized cross-origin actions - such as issuing requests or navigating frames to restricted origins - impacting integrity of cross-origin content. … |
| Remediation | Update Google Chrome on Android to version 150.0.7871.47 or later - this is the vendor-confirmed fixed release per the Chrome stable channel advisory at https://chromereleases.googleblog.com/2026/06/stable-channel-update-for-desktop_0175352312.html. … Detailed patch versions, workarounds, and compensating controls in full report. |
