Use after free in Payments in Google Chrome prior to 153.0.8010.36 allowed a remote attacker to potentially execute arbitrary code outside the sandbox via a crafted HTML page. (Chromium security severity: High)
AnalysisAI
Remote code execution in Google Chrome before 153.0.8010.36 stems from a use-after-free in the browser's Payments component, letting a remote attacker who lures a victim to a crafted HTML page potentially execute arbitrary code outside the renderer sandbox. Chromium rates the severity High, and the supplied CVSS is 9.6 reflecting the sandbox-escape scope change. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires a remote, unauthenticated attacker (PR:N) to get the victim to load attacker-controlled HTML in a vulnerable Chrome build (UI:R - user must open the page), and the crafted content must exercise the Payments component to drive the use-after-free. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS vector (AV:N/AC:L/PR:N/UI:R/S:C/C:H/I:H/A:H = 9.6) describes a network-reachable, low-complexity, unauthenticated bug that only requires the victim to open a page, with a scope change consistent with sandbox escape - a genuinely serious profile for a browser. … 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 via the Chrome Releases advisory (https://chromereleases.googleblog.com/2026/09/stable-channel-update-for-desktop_0808145027.html); most installations receive this automatically, so verify the update applied and fully relaunch the browser to load the new binary. … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
Within 24 hours, inventory all Chrome installations to identify instances running versions prior to 153.0.8010.36 and assess deployment scope across managed and unmanaged endpoints. …
