DescriptionCVE.org

Inappropriate implementation in Autofill in Google Chrome on Android prior to 151.0.7922.72 allowed a remote attacker to leak cross-origin data via a crafted HTML page. (Chromium security severity: Medium)

AnalysisAI

Cross-origin data leakage in Google Chrome's Autofill feature on Android prior to 151.0.7922.72 allows a remote unauthenticated attacker to read limited data belonging to another origin by luring a victim to a specially crafted HTML page. The flaw is classified as CWE-346 (Origin Validation Error), meaning the Autofill subsystem fails to enforce same-origin boundaries when processing or exposing form data. No active exploitation is confirmed (SSVC: Exploitation none; EPSS 0.21%, 11th percentile), and a vendor patch is available in the 151.0.7922.72 stable release.

Technical ContextAI

CWE-346 (Origin Validation Error) is the root cause class - the application accepts data or exposes functionality without properly verifying that the requesting context shares the same origin. Chrome's Autofill on Android interacts with form fields across page contexts and, when improperly implemented, can surface autofill-populated data to scripts or frames from a different origin, violating the Same-Origin Policy. The CPE (cpe:2.3:a:google:chrome:*:*:*:*:*:*:*:*) covers Google Chrome broadly, but the CVE description and the EUVD affected-versions entry explicitly scope the flaw to Chrome on Android prior to 151.0.7922.72. The Chromium issue tracker reference (https://issues.chromium.org/issues/463551850) is not publicly accessible at time of analysis, so the precise Autofill code path is not independently verifiable from open sources.

RemediationAI

Update Google Chrome on Android to version 151.0.7922.72 or later. The vendor-released patch is documented in the Chrome stable channel update at https://chromereleases.googleblog.com/2026/07/stable-channel-update-for-desktop_0887107924.html. Android users should verify their Chrome version via Settings > About Chrome and apply the update through the Google Play Store. As a compensating control prior to patching, disabling Autofill in Chrome Android (Settings > Autofill and passwords > toggle off payment methods, addresses, and passwords autofill) removes the vulnerable code path but eliminates autofill functionality - a trade-off acceptable in high-sensitivity environments. Enterprise administrators can enforce the minimum version via Android Enterprise MDM policies (e.g., Chrome Browser Cloud Management minimum version policy). No workaround fully substitutes for patching.
