Use after free in WebXR in Google Chrome prior to 148.0.7778.216 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 versions prior to 148.0.7778.216 stems from a use-after-free flaw in the WebXR component, allowing a remote attacker to run arbitrary code within the browser's renderer sandbox by enticing a victim to visit a crafted HTML page. Google rates the underlying Chromium severity as High, and a vendor patch has been released; no public exploit identified at time of analysis.
Technical ContextAI
WebXR is the W3C-standardized Chromium subsystem that exposes virtual and augmented reality device APIs (Device API, Gamepad input, immersive sessions) to JavaScript running in the page, implemented in Blink with IPC bridges to GPU and device services. CWE-416 (Use After Free) indicates that the WebXR implementation continues to dereference a heap object after it has been freed - typically the result of mismatched object lifetimes across asynchronous session callbacks, garbage-collected JS wrappers, or device disconnect events - which can be groomed into a type-confused or attacker-controlled allocation usable to hijack control flow. The affected CPE (cpe:2.3:a:google:chrome:*:*:*:*:*:*:*:*) covers all Chrome desktop builds before 148.0.7778.216 across platforms that ship the WebXR feature.
RemediationAI
Vendor-released patch: Google Chrome 148.0.7778.216 - upgrade all desktop Chrome installations to this version or later, per the Stable Channel update at https://chromereleases.googleblog.com/2026/05/stable-channel-update-for-desktop_0877304591.html, and force-restart the browser so the new binary loads (Chrome's silent updater stages the fix but a session restart is required to activate it). For managed fleets, push the update via Chrome Browser Cloud Management or platform MDM and verify the running version through chrome://version. Until rollout completes, an effective compensating control is disabling the WebXR Device API by setting the enterprise policy WebXRImmersiveArSupportEnabled to false (or launching with --disable-features=WebXR), which neutralizes the vulnerable code path at the cost of breaking legitimate VR/AR web applications; users of Chromium-derived browsers (Edge, Brave, Opera, Electron apps) should apply vendor updates as soon as they incorporate the upstream Chromium fix.
