Type confusion in V8 in Google Chrome prior to 152.0.7977.65 allowed a remote attacker leveraging social engineering to execute arbitrary code inside the sandbox via a crafted HTML page. (Chromium security severity: Low)
AnalysisAI
Type confusion in Chrome's V8 JavaScript engine (versions prior to 152.0.7977.65) enables remote code execution within the browser sandbox when a victim is socially engineered into visiting a crafted HTML page. The vulnerability arises from a CWE-843 type confusion flaw in V8, allowing an attacker to manipulate object type assumptions at runtime to achieve arbitrary code execution. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires that the victim be running Google Chrome prior to version 152.0.7977.65 and be socially engineered into visiting a crafted HTML page - user interaction (UI:R) is mandatory, meaning the attack cannot be automated without a social engineering step. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 8.8 score reflects high confidentiality, integrity, and availability impact with a network attack vector and no privilege requirement, but the score must be weighed against several limiting signals. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker crafts a malicious HTML page containing JavaScript designed to trigger the V8 type confusion bug, then distributes it via phishing email, malicious ad, or compromised website. A victim running an unpatched version of Chrome is socially engineered into visiting the page, at which point the script executes and achieves arbitrary code execution within Chrome's renderer sandbox. … |
| Remediation | Update Google Chrome to version 152.0.7977.65 or later, which contains the vendor-released patch per the Stable Channel Update advisory at https://chromereleases.googleblog.com/2026/08/stable-channel-update-for-desktop_0256176589.html. … Detailed patch versions, workarounds, and compensating controls in full report. |
