AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H
Network-delivered malicious page needs no auth (PR:N) but requires the victim to open it (UI:R); code runs in the renderer sandbox so scope unchanged (S:U) with full CIA impact.

Use after free in V8 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)
AnalysisAI
Remote code execution in Google Chrome's V8 JavaScript engine (versions prior to 151.0.7922.72) allows a remote attacker to run arbitrary code within the browser's renderer sandbox by luring a victim to a crafted HTML page. The flaw is a use-after-free (CWE-416) rated High by Chromium and CVSS 8.8, requiring user interaction (visiting a page) but no authentication. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires the victim to actively load a crafted HTML/JavaScript page in a vulnerable Chrome build (< 151.0.7922.72) - the CVSS UI:R confirms mandatory user interaction, which is the primary limiting factor. … 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) indicates a network-reachable, low-complexity, unauthenticated attack that requires user interaction (visiting a malicious page) and stays within the renderer's scope (S:U) with high confidentiality, integrity, and availability impact. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker registers or compromises a website and embeds malicious JavaScript that manipulates V8 object lifetimes to trigger the use-after-free, then phishes or otherwise entices a victim to open the page. Because AC is low and no authentication is needed, simply rendering the crafted HTML corrupts memory and can execute attacker code within the renderer sandbox; full host compromise would require chaining a separate sandbox escape. … |
| Remediation | Vendor-released patch: update Google Chrome to 151.0.7922.72 or later via the Stable channel; verify the exact fixed build for your platform in Google's advisory at https://chromereleases.googleblog.com/2026/07/stable-channel-update-for-desktop_0887107924.html. … Detailed patch versions, workarounds, and compensating controls in full report. |
