DescriptionCVE.org

Insufficient validation of untrusted input in Media in Google Chrome prior to 149.0.7827.53 allowed a remote attacker who had compromised the renderer process to potentially perform a sandbox escape via a crafted HTML page. (Chromium security severity: High)

AnalysisAI

Sandbox escape in Google Chrome versions prior to 149.0.7827.53 allows a remote attacker who has already compromised the renderer process to break out of the browser sandbox via a crafted HTML page abusing the Media component. Google rates the issue High severity and a vendor patch is available, though no public exploit has been identified at time of analysis.

Technical ContextAI

The flaw resides in Chrome's Media subsystem, which handles audio/video decoding, playback, and related IPC between the renderer and browser process. CWE-20 (Improper Input Validation) indicates that data crossing the renderer-to-broker boundary is not adequately validated, enabling a renderer with attacker control to manipulate Media-layer logic and escape the sandbox confinement that normally isolates web content from the host OS. Chromium's sandbox is a defense-in-depth boundary, so a flaw here breaks one of the browser's most critical security guarantees and affects the same engine shipped in Chrome and Chromium-derived browsers.

RemediationAI

Update to Google Chrome 149.0.7827.53 or later on all desktop platforms per the Stable Channel advisory at https://chromereleases.googleblog.com/2026/06/stable-channel-update-for-desktop.html; this is the vendor-released patch and is the only complete fix. Force-restart browsers after the update to ensure the new binary is loaded, and verify Chromium-derived browsers (Edge, Brave, Opera, Electron-based apps) have picked up an equivalent merge before considering them remediated. As a compensating control until rollout completes, enterprises can enforce Site Isolation (already default), enable the enhanced Safe Browsing setting, and restrict browsing to allowlisted domains via group policy - these reduce the likelihood of encountering a chained renderer-RCE payload but do not prevent exploitation if a user visits a malicious page.
