Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
Insufficient validation of untrusted input in WebAppInstalls in Google Chrome prior to 150.0.7871.47 allowed a remote attacker who had compromised the renderer process to perform UI spoofing via a crafted HTML page. (Chromium security severity: Low)

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 · high confidence

Insufficient validation of untrusted input in Chrome's WebAppInstalls component allows a remote attacker with an already-compromised renderer process to perform UI spoofing via a crafted HTML page. The vulnerability exists in versions prior to 150.0.7871.47 and stems from improper handling of HTML content during web app installation.

MitigationUpdate Google Chrome to version 150.0.7871.47 or later to patch the vulnerability; users should ensure their browser is current.

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 checks

Work through these to decide whether this CVE applies to you.

  1. Verify Google Chrome is installed
    Check for Chrome executable: On Windows, look in C:\Program Files\Google\Chrome\Application\chrome.exe or C:\Program Files (x86)\Google\Chrome\Application\chrome.exe. On macOS, check /Applications/Google Chrome.app. On Linux, check /usr/bin/google-chrome or /opt/google/chrome/google-chrome.
    Affected if Chrome browser is present on the system
  2. Determine installed Chrome version
    Open chrome://version in the Chrome browser address bar, or run 'google-chrome --version' from command line on Linux/Mac, or check the executable properties on Windows.
    Affected if Unable to retrieve version information indicates Chrome may not be properly installed
  3. Compare version against affected range
    Parse the version number obtained and compare it numerically to 150.0.7871.47. Any version less than 150.0.7871.47 is in the affected range.
    Affected if Installed version is less than 150.0.7871.47 (for example, 150.0.7871.0, 149.0.5555.100, etc.)
  4. Assess renderer compromise risk
    This vulnerability requires an already-compromised renderer process to be exploitable. Check for signs of browser compromise: unexpected extensions, unusual homepage/search engine changes, unknown cookies/sites in chrome://settings/cookies, or detection of malware on the system.
    Affected if The renderer process is already compromised through other means (malware, malicious extension, or other exploitation)

A user is affected if they have Google Chrome installed with a version prior to 150.0.7871.47 AND their renderer process has already been compromised by an attacker.
