UNKNOWN (no severity yet)

DescriptionCVE.org

Insufficient validation of untrusted input in UI in Google Chrome on Android prior to 150.0.7871.47 allowed a local attacker to perform privilege escalation via a malicious file. (Chromium security severity: Medium)

AnalysisAI

Local privilege escalation in Google Chrome for Android before 150.0.7871.47 stems from insufficient validation of untrusted input in the browser UI, letting a local attacker who convinces a user to open a malicious file gain elevated privileges. Rated Medium by Chromium but scored CVSS 7.8 (total technical impact per SSVC), with no public exploit identified at time of analysis and a low EPSS of 0.13% (3rd percentile). Google has shipped a fixed Stable channel build.

Technical ContextAI

The flaw is a CWE-20 Improper Input Validation issue in Chrome's user-interface handling of untrusted input, specifically in how the Android build processes a supplied file. Chrome is a Chromium-based browser; the CPE cpe:2.3:a:google:chrome:*:*:*:*:*:*:*:* identifies the affected application, though the description narrows the impact to the Android platform. Because validation of the untrusted file input is incomplete, a crafted file can drive the UI into an unintended state that crosses a privilege boundary within the browser or the local sandbox model, yielding the escalation described.

RemediationAI

Update Google Chrome to 150.0.7871.47 or later - Vendor-released patch: 150.0.7871.47 - via the Chrome Stable channel update announced at https://chromereleases.googleblog.com/2026/06/stable-channel-update-for-desktop_0175352312.html; on Android this arrives through the Google Play Store, so ensure automatic updates are enabled and force-update managed fleets via MDM. Until the update is applied, the practical compensating control is to avoid opening untrusted or unexpected files through Chrome and to restrict sideloading of files from unknown sources; because exploitation requires the user to open a malicious file, user-awareness and blocking untrusted downloads meaningfully reduce exposure, at the cost of some workflow friction. No workaround fully substitutes for the patch given the total technical impact.
