DescriptionCVE.org

Insufficient validation of untrusted input in CustomTabs 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

Privilege escalation in Google Chrome for Android (CustomTabs) prior to 150.0.7871.47 allows a local attacker to escalate privileges by supplying a malicious file that CustomTabs fails to validate properly. Google rates the Chromium severity as Medium, and the requirement for user interaction plus local access limits remote mass exploitation. …

Impact
Privilege escalation in browser context

Vulnerability AssessmentAI

Exploitation Exploitation requires local access to the Android device and involves Chrome's CustomTabs feature: an attacker (typically a malicious app already installed on the device, or a malicious file placed on it) must supply crafted untrusted input via a file, and the victim must perform an interaction that causes Chrome to process it (CVSS UI:R). … Additional conditions and limiting factors are described in the full assessment.
Risk Assessment The CVSS 3.1 vector (AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H, score 7.8 High) describes a local, low-complexity, no-privilege attack that nonetheless requires user interaction and yields high confidentiality, integrity, and availability impact. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in.
Exploit Scenario A user installs a malicious or compromised Android app; when the user taps a link or content that opens in a Chrome CustomTab, the app passes a crafted malicious file whose untrusted input Chrome fails to validate, letting the attacker escalate privileges within the browser context on the device. The single required user interaction is realistic during normal app usage. …
Remediation Vendor-released patch: update Google Chrome for Android to version 150.0.7871.47 or later, delivered through the Chrome Releases stable channel (https://chromereleases.googleblog.com/2026/06/stable-channel-update-for-desktop_0175352312.html); on Android this arrives via Google Play, so ensure automatic app updates are enabled or manually update Chrome from the Play Store. … Detailed patch versions, workarounds, and compensating controls in full report.
