Use after free in Passwords in Google Chrome on Windows prior to 148.0.7778.216 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 on Windows prior to 148.0.7778.216 allows a remote attacker who has already compromised the renderer process to break out via a use-after-free in the Passwords component, delivered through a crafted HTML page. Exploitation requires user interaction and high attack complexity, and no public exploit identified at time of analysis, though Google rates the underlying Chromium severity as High and a vendor patch is available.

Technical ContextAI

The flaw resides in Chrome's Passwords subsystem and is a CWE-416 Use-After-Free, where memory is referenced after being freed, enabling an attacker who controls renderer-side execution to corrupt heap state and pivot across the sandbox boundary. The affected component (cpe:2.3:a:google:chrome:*:*:*:*:*:*:*:*) is the Chromium-based browser on Windows; sandbox escapes in Chrome typically require chaining a renderer compromise (separate bug) with a UAF in a higher-privileged browser-process feature like the password manager IPC handlers, leveraging the CVSS Scope:Changed property which indicates the impact extends beyond the originally vulnerable component.

RemediationAI

Vendor-released patch: update Chrome on Windows to 148.0.7778.216 or later via Chrome's auto-update or by relaunching the browser (Help > About Google Chrome); enterprise admins can deploy via the Chrome Enterprise MSI or Group Policy as described in Google's advisory at https://chromereleases.googleblog.com/2026/05/stable-channel-update-for-desktop_0877304591.html. Users of Chromium-based browsers (Edge, Brave, Opera) should apply their vendor's corresponding update once published. As a compensating control until patched, restrict browsing to trusted sites and enable Enhanced Safe Browsing, and consider disabling the built-in password manager via the PasswordManagerEnabled=false policy (side effect: users lose autofill and must use an external password manager); blocking untrusted HTML rendering at proxy level is impractical for general browsing.
