Observable discrepancy in Safebrowsing in Google Chrome on on iOS prior to 153.0.8010.36 allowed a remote attacker who had compromised the renderer process to potentially obtain sensitive information via a crafted HTML page. (Chromium security severity: Medium)
AnalysisAI
Observable discrepancy (CWE-203) in the Safebrowsing component of Google Chrome on iOS prior to 153.0.8010.36 enables a remote attacker with a pre-compromised renderer process to leak sensitive information through behavioral differences when processing a crafted HTML page. The vulnerability is iOS-platform-specific and is chained after renderer compromise rather than exploited standalone. …

Vulnerability AssessmentAI
| Exploitation | Exploitation requires two sequential conditions: first, a pre-existing compromise of the Chrome renderer process on iOS (itself requiring exploitation of a separate vulnerability or existing malware on the device), and second, the victim must visit an attacker-controlled crafted HTML page (UI:R). … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 5.3 (Medium) score accurately reflects the high attack complexity imposed by the prerequisite of a pre-compromised renderer process - an already substantial exploit in its own right. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | Full exploit scenario with step-by-step reproduction available after sign-in. |
| Remediation | Vendor-released patch: Chrome 153.0.8010.36 for iOS. … Detailed patch versions, workarounds, and compensating controls in full report. |
