Use after free in V8 in Google Chrome prior to 149.0.7827.103 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 prior to version 149.0.7827.103 allows a remote attacker to execute arbitrary code within the renderer sandbox by enticing a user to visit a crafted HTML page. The flaw is a use-after-free memory corruption issue rated High severity by Chromium and carries a CVSS 8.8 score; no public exploit identified at time of analysis, but V8 UAF bugs are historically high-value targets for exploit chains.

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | The victim must run a vulnerable Chrome desktop build (any version below 149.0.7827.103 on the stable channel) and must actively load attacker-controlled HTML/JavaScript in the browser (UI:R - clicking a link, visiting a malicious site, loading a malicious ad, or rendering an attacker-supplied iframe). … 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) describes a network-reachable, low-complexity, unauthenticated attack that requires a single user interaction (visiting a page) and full CIA impact on the renderer process, which is realistic for a browser drive-by. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker hosts or compromises a website serving a malicious HTML/JavaScript payload that triggers the V8 use-after-free, then lures a victim via phishing, malvertising, or a watering-hole compromise to visit the page in a vulnerable Chrome build. Once the UAF fires inside V8, the attacker gains arbitrary code execution in the renderer sandbox, typically used for credential theft from same-origin tabs, in-memory keystroke capture, or as the first stage of a chained sandbox escape to achieve full host compromise. … |
| Remediation | Vendor-released patch: update Google Chrome to 149.0.7827.103 or later via the stable channel auto-updater, per the Chrome Releases advisory at https://chromereleases.googleblog.com/2026/06/stable-channel-update-for-desktop_0153744567.html, and restart the browser to ensure the new V8 binary is loaded. … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
Within 24 hours: Issue mandatory browser update alert to all Chrome users; assess deployment infrastructure and mobile device coverage. …
