Use after free in Passwords in Google Chrome prior to 153.0.8010.36 allowed a remote attacker leveraging social engineering to potentially execute arbitrary code outside the sandbox via UI Interaction. (Chromium security severity: Medium)
AnalysisAI
Remote code execution in Google Chrome (desktop) prior to 153.0.8010.36 stems from a use-after-free in the Passwords component that, when triggered via crafted UI interaction and social engineering, can let a remote attacker escape the renderer sandbox and run arbitrary code. All Chrome desktop builds before the 153.0.8010.36 stable release are affected. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires the victim to run an unpatched Chrome desktop build (before 153.0.8010.36), visit or be served attacker-controlled web content, and - critically - perform a specific UI interaction driven by social engineering (CVSS UI:R). … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The provided CVSS 3.1 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 whose only gate is user interaction, with sandbox escape driving the scope change and full C/I/A impact - a genuinely high-priority browser flaw if the sandbox-escape claim holds. … 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 Stable channel (Settings → About Chrome, then relaunch to apply), as described in Google's advisory at https://chromereleases.googleblog.com/2026/09/stable-channel-update-for-desktop_0808145027.html. … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
Within 24 hours, deploy Google Chrome version 153.0.8010.36 or later across all enterprise systems using automated deployment tools (MDM, SCCM, or managed auto-update); prioritize systems still running versions prior to 153.0.8010.36. …
