Insufficient validation of untrusted input in Codecs in Google Chrome prior to 149.0.7827.53 allowed a remote attacker to potentially perform a sandbox escape via a crafted video file. (Chromium security severity: Medium)

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

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: Windows (C:\Program Files\Google\Chrome\Application\chrome.exe), Mac (/Applications/Google Chrome.app), or Linux (common paths /usr/bin/google-chrome, /usr/bin/chromium-browser)
    Affected if Google Chrome browser is found on the system
  2. Determine installed Chrome version
    Navigate to chrome://version in the Chrome address bar or run 'google-chrome --version' (Linux) or '"C:\Program Files\Google\Chrome\Application\chrome.exe" --version' (Windows CMD)
    Affected if Unable to retrieve version information
  3. Compare version against affected range
    Parse the version number from step 2 and compare it to 149.0.7827.53 using semantic version comparison
    Affected if Installed version is lower than 149.0.7827.53 (e.g., 149.0.7827.52, 148.x.x.x, etc.)
  4. Identify Codecs component usage
    The vulnerable Codecs component is used when Chrome processes video or audio files. Check browser history or downloads for recently opened media files, or simply note that any video playback in Chrome uses this component
    Affected if Chrome is used to play video or audio files (this is the attack vector)

If the installed Chrome version is below 149.0.7827.53 and the browser is used to open untrusted video files, the environment is affected by this vulnerability.
