Use after free in Autofill in Google Chrome on Android 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 on Android prior to 149.0.7827.53 allows a remote attacker who already controls the renderer process to break out of the browser sandbox via a crafted HTML page that triggers a use-after-free in the Autofill component. Chromium rates the severity High and a vendor patch is available; no public exploit identified at time of analysis and the issue is not listed in CISA KEV.

Technical ContextAI

The flaw is a CWE-416 use-after-free in Chrome's Autofill subsystem on Android. Autofill runs in the browser process and handles form-field suggestions sourced from saved profiles and payment data; when the renderer interacts with it through Mojo IPC, freed C++ objects can be referenced again, yielding an attacker-controlled dangling pointer that is reachable from a compromised renderer. Because Autofill code executes outside the renderer sandbox, corrupting its memory provides a path to escalate from renderer RCE (typically obtained through a prior bug) into the higher-privileged browser process, undermining Chrome's site-isolation and sandbox boundary on Android (Chromium issue 501594107).

RemediationAI

Vendor-released patch: Google Chrome for Android 149.0.7827.53 or later - update via Google Play or the Chrome Releases advisory at https://chromereleases.googleblog.com/2026/06/stable-channel-update-for-desktop.html. Because exploitation requires a pre-existing compromised renderer plus user interaction with a crafted page, interim compensating controls for fleets that cannot immediately update include disabling Autofill for addresses and payment methods in chrome://settings/autofill (reduces the attack surface of the vulnerable component at the cost of user convenience), and enforcing managed-browser policies such as AutofillAddressEnabled=false and AutofillCreditCardEnabled=false via Android enterprise MDM. Restricting users to known-good sites via SafeBrowsing Enhanced Protection and URL allowlists further limits exposure to attacker-controlled HTML, though it does not address the underlying memory-corruption bug.
