Type Confusion in WebRTC in Google Chrome prior to 148.0.7778.96 allowed a remote attacker to execute arbitrary code inside a sandbox via a crafted HTML page. (Chromium security severity: Medium)
AnalysisAI
Remote code execution in Google Chrome's WebRTC implementation (versions prior to 148.0.7778.96) allows attackers to execute arbitrary code within the browser sandbox through a malicious HTML page exploiting type confusion in WebRTC. Patch available via Chrome 148.0.7778.96. Requires user interaction (visiting crafted page) but no authentication. CVSS 8.8 reflects high impact across confidentiality, integrity, and availability within sandbox constraints. No confirmed active exploitation or public POC identified at time of analysis.
Technical ContextAI
This vulnerability stems from CWE-843 (Type Confusion), a memory corruption class where code incorrectly handles an object as a different type than intended. WebRTC (Web Real-Time Communication) is Chrome's implementation of peer-to-peer audio, video, and data communication APIs used by web applications for videoconferencing and real-time collaboration. Type confusion vulnerabilities in WebRTC typically occur during complex object handling in media stream processing, codec negotiation, or peer connection establishment. When exploited, the type mismatch causes the browser to misinterpret memory structures, potentially allowing controlled memory writes that lead to code execution. The CPE string cpe:2.3:a:google:chrome identifies all Chrome browser installations across platforms (Windows, macOS, Linux, ChromeOS) as affected prior to the patched version. Chromium's security severity rating of 'Medium' (contrasting with CVSS 8.8 'High') likely reflects sandboxing effectiveness limiting post-exploitation impact.
RemediationAI
Update Google Chrome to version 148.0.7778.96 or later immediately via Chrome's built-in automatic update mechanism (chrome://settings/help) or manual download from google.com/chrome. Chrome typically auto-updates within 24-48 hours for most users. Enterprise deployments should push Chrome 148.0.7778.96 through managed update channels (GPO/SCCM/MDM). For environments unable to immediately patch, compensating controls include: disabling JavaScript via chrome://settings/content/javascript (breaks most web applications - only viable for limited-use kiosks), blocking access to untrusted websites through web proxy/firewall rules (reduces social engineering attack surface but requires maintaining allowlists), or restricting WebRTC functionality via Chrome policy WebRtcUdpPortRange (empty value disables WebRTC - impacts videoconferencing/collaboration tools). Official advisory at http://chromereleases.googleblog.com/2026/05/stable-channel-update-for-desktop.html and technical details at https://issues.chromium.org/issues/498753456 provide vendor confirmation.
