DescriptionCVE.org

Insufficient validation of untrusted input in File Input in Google Chrome on Android prior to 150.0.7871.47 allowed a remote attacker to leak cross-origin data via a crafted HTML page. (Chromium security severity: High)

AnalysisAI

Cross-origin data leakage in Google Chrome for Android prior to 150.0.7871.47 enables remote attackers to read data from other origins via a crafted HTML page exploiting insufficient validation in the File Input component. The flaw is Android-platform-specific, requiring only that a victim user navigate to an attacker-controlled page. No active exploitation has been confirmed (CISA KEV negative, SSVC exploitation: none), and EPSS at 0.21% (11th percentile) reflects low current exploitation interest, though the unauthenticated, low-complexity attack vector keeps it a relevant patching priority for Android Chrome deployments.

Technical ContextAI

The vulnerability resides in Google Chrome's File Input handling (<input type='file'>) on the Android platform. CWE-20 (Improper Input Validation) indicates that the browser fails to sufficiently validate or sanitize untrusted HTML input before processing file-related data, allowing the same-origin policy to be bypassed and enabling cross-origin data leakage. This is an Android-specific manifestation, likely related to how Chrome on Android handles file URI schemes, content providers, or the Android-specific file picker integration differently from desktop builds. The affected CPE scope covers all Chrome builds for Android below version 150.0.7871.47.

RemediationAI

Update Google Chrome on Android to version 150.0.7871.47 or later. This patch is available via the Google Play Store automatic update mechanism or manually through Play Store > Chrome > Update. The vendor advisory is published at http://chromereleases.googleblog.com/2026/06/stable-channel-update-for-desktop_0175352312.html. As a compensating control prior to patching, organizations managing Android devices through MDM can restrict browser-based file input access or enforce Safe Browsing policies to reduce exposure to malicious pages. Note that enterprise fleets using Chrome for Android via managed profiles should prioritize this update specifically on Android endpoints, as the vulnerability does not affect Chrome on other platforms.
