Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · moderate confidenceA vulnerability in Google Chrome's WebView component on Android allows a remote attacker to perform privilege escalation via a crafted HTML page. The 'inappropriate implementation' suggests a security boundary bypass within the WebView sandbox that could allow a malicious webpage to gain elevated access.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Check if Google Chrome is installed on the Android deviceOpen device Settings > Apps > Chrome, or look for Chrome in the app drawer. If Chrome is not installed, this specific CVE may not apply directly.Affected if Google Chrome app is installed on the Android device and its version is less than 149.0.7827.155
-
Determine the installed Chrome version on AndroidOpen Chrome app, tap the three-dot menu > Settings > About Chrome. The version number is displayed on this page.Affected if The displayed version number is below 149.0.7827.155 (for example, 149.0.7827.150 or any earlier version)
-
Confirm WebView is using Chrome as the provider (optional context)On Android 7.0 and later, check Settings > Apps > Chrome. If Chrome is listed as a WebView provider, it may be handling WebView rendering for other apps.Affected if Chrome serves as the WebView provider and its version is vulnerable, potentially expanding the attack surface to other apps using WebView
A user is affected if Google Chrome for Android is installed and its version is lower than 149.0.7827.155, as the WebView component in those versions contains the privilege escalation vulnerability.
