Use after free in Autofill in Google Chrome prior to 151.0.7922.72 allowed a remote attacker to execute arbitrary code inside a sandbox via a crafted HTML page. (Chromium security severity: High)
Articles & Coverage 1
AnalysisAI
Remote code execution in Google Chrome desktop before 151.0.7922.72 stems from a use-after-free in the Autofill component, letting a remote attacker who lures a victim to a crafted HTML page run arbitrary code within the renderer sandbox. Rated High by Chromium and CVSS 8.8, it requires user interaction (visiting a malicious page) but no authentication. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires the victim to actively load attacker-controlled HTML in a vulnerable Chrome build (before 151.0.7922.72) - the CVSS UI:R confirms user interaction (navigating to or rendering the crafted page) is mandatory; there is no drive-by-with-zero-interaction path from the available data. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 3.1 vector (AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H, 8.8 High) reflects network reachability, low complexity, no privileges, but required user interaction and an unchanged scope, meaning the compromise stays within the sandboxed renderer. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker hosts a malicious web page (or injects one via a compromised ad/iframe) that programmatically manipulates form fields to trigger the Autofill use-after-free and grooms the renderer heap. When a victim running a pre-151.0.7922.72 Chrome visits the page, the dangling pointer is dereferenced and attacker-controlled code executes inside the renderer sandbox. … |
| Remediation | Vendor-released patch: update Google Chrome to 151.0.7922.72 or later on the Stable channel; verify via chrome://settings/help which forces an update check and relaunch. … Detailed patch versions, workarounds, and compensating controls in full report. |
