Use after free in Payments in Google Chrome on on Mac prior to 153.0.8010.36 allowed a remote attacker to execute arbitrary code outside the sandbox via a crafted HTML page. (Chromium security severity: High)
AnalysisAI
Remote code execution in Google Chrome on macOS prior to 153.0.8010.36 stems from a use-after-free in the Payments component, letting a remote attacker who lures a user to a crafted HTML page execute arbitrary code outside the browser sandbox. The provided CVSS vector (9.6) reflects a scope-changing sandbox escape requiring user interaction (a page visit), while Chromium rated the underlying bug 'High' rather than 'Critical'. …

Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires a macOS user running Chrome prior to 153.0.8010.36 to visit or render an attacker-controlled HTML page (UI:R - user interaction in the form of a page visit is required); the vulnerable path is in the Payments component, so triggering conditions relate to that subsystem's object handling reached from web content. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | Signals are mixed but lean toward prioritized patching. … 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: update Google Chrome to 153.0.8010.36 or later on macOS via the Chrome Releases stable-channel advisory (https://chromereleases.googleblog.com/2026/09/stable-channel-update-for-desktop_0808145027.html); restart the browser to ensure the update applies, and in managed environments push the update through MDM/enterprise policy and verify the running version. … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
