Insufficient validation of untrusted input in PDF in Google Chrome on Android prior to 151.0.7922.72 allowed a local attacker to leak cross-origin data via a crafted HTML page. (Chromium security severity: High)
AnalysisAI
Cross-origin data leakage in Google Chrome's PDF component on Android (prior to 151.0.7922.72) exposes sensitive data from one web origin to an attacker-controlled page due to insufficient input validation in PDF processing. A local attacker who can direct a victim to a crafted HTML page triggers the flaw, allowing confidentiality impact with no integrity or availability consequence. No public exploit code exists and EPSS sits at 0.18% (8th percentile), indicating low real-world exploitation probability at time of analysis despite a High Chromium severity rating.
Technical ContextAI
The vulnerability resides in Google Chrome's PDF rendering subsystem on the Android platform, as identified by CPE cpe:2.3:a:google:chrome:*:*:*:*:*:*:*:*. The root cause is CWE-20 (Improper Input Validation), meaning Chrome fails to adequately validate untrusted content supplied through PDF processing when that content is embedded or triggered via an HTML page. The cross-origin data leak implies the PDF component does not correctly enforce the Same-Origin Policy or equivalent isolation boundaries under certain input conditions, allowing data from origins other than the attacker's to be read. This is an Android-specific code path, suggesting the vulnerability may relate to Chrome's Android PDF viewer integration rather than the shared Chromium renderer used on desktop platforms.
RemediationAI
Vendor-released patch: Chrome 151.0.7922.72 for Android, detailed in the stable channel update advisory at chromereleases.googleblog.com/2026/07/stable-channel-update-for-desktop_0887107924.html. Update Chrome on Android to version 151.0.7922.72 or later via the Google Play Store. As a compensating control prior to patching, users can avoid opening PDF content directly in Chrome on Android - using a dedicated offline PDF reader application eliminates the vulnerable code path. Disabling JavaScript or using Chrome's site isolation flags may reduce cross-origin leakage surface but carries significant compatibility trade-offs with modern web applications and is not a reliable substitute for the patch. Enterprise administrators managing Android fleets should prioritize the update through their MDM solution.
