Severity by source
AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H
Network-delivered via crafted page needing only user interaction (UI:R, PR:N, AC:L); high renderer-process impact retained, though sandbox containment (S:U) means host compromise needs a further escape.

Use after free in Extensions in Google Chrome prior to 150.0.7871.47 allowed a remote attacker to execute arbitrary code inside a sandbox via a crafted HTML page. (Chromium security severity: Medium)
AnalysisAI
Use-after-free in the Extensions component of Google Chrome before 150.0.7871.47 lets a remote attacker execute arbitrary code within the renderer sandbox when a victim opens a crafted HTML page. Chromium rated the security severity Medium, though the associated CVSS score is 8.8 (High) due to network vector and high impact; there is no public exploit identified at time of analysis and EPSS exploitation probability is low at 0.26%. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires the victim to actively open or navigate to attacker-controlled HTML (CVSS UI:R), so this is not a zero-click bug - user interaction is the primary limiting factor. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | Signals here are mixed and should be weighed rather than taken at face value. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker hosts a crafted HTML page and lures a victim into visiting it via a phishing link, malvertising, or a compromised site. When the page loads it triggers the use-after-free in the Extensions component, giving the attacker arbitrary code execution inside the renderer sandbox; a serious campaign would pair this with a separate sandbox-escape to reach the host. … |
| Remediation | Vendor-released patch: update Google Chrome to 150.0.7871.47 or later on the Stable channel, as announced in Google's release notes at https://chromereleases.googleblog.com/2026/06/stable-channel-update-for-desktop_0175352312.html; the bug is tracked at https://issues.chromium.org/issues/500566906. … Detailed patch versions, workarounds, and compensating controls in full report. |
