Insufficient validation of untrusted input in WebRTC in Google Chrome prior to 150.0.7871.47 allowed a remote attacker to perform privilege escalation via a crafted HTML page. (Chromium security severity: Low)
AnalysisAI
Privilege escalation in Google Chrome's WebRTC component (versions prior to 150.0.7871.47) allows a remote attacker to escape normal renderer restrictions when a victim opens a crafted HTML page, per the CVSS vector achieving high confidentiality, integrity, and availability impact. Exploitation requires user interaction (visiting a malicious page) but no prior authentication. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires the victim to actively open or navigate to an attacker-controlled HTML page that exercises the WebRTC code path (UI:R in the CVSS vector) - it is not a fully automatic or drive-by-with-no-interaction flaw. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | Signals conflict and should be reconciled before prioritization. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker hosts a malicious web page containing crafted WebRTC-triggering content and lures a victim to visit it via phishing, malvertising, or a compromised site. When the page loads, the malformed input reaches Chrome's WebRTC handler and, due to insufficient validation, escalates the attacker's privileges within the browser. … |
| Remediation | Vendor-released patch: update Google Chrome to 150.0.7871.47 or later via the Stable channel; on most installs this arrives automatically, so trigger it by opening chrome://settings/help and relaunching the browser to force the update to complete. … Detailed patch versions, workarounds, and compensating controls in full report. |
