dbcve checksWork through these to decide whether this CVE applies to you.
-
Identify Chrome installationOpen Chrome, click the three-dot menu, select Help > About Google Chrome. Alternatively, navigate to chrome://settings/help in the address bar.Affected if Chrome is not installed or cannot be located
-
Check installed Chrome versionIn the About Google Chrome page, note the version number displayed next to 'Google Chrome'. Compare this version against the affected range: versions prior to 148.0.7778.96 are vulnerable.Affected if The installed version is below 148.0.7778.96 (e.g., 148.0.7778.0 to 148.0.7778.95)
-
Confirm WebCodecs API accessibilityWebCodecs API is enabled by default in Chrome. To verify, open Developer Tools (F12), go to the Console, and enter 'window.VideoDecoder !== undefined' to check if the API is available.Affected if The WebCodecs API returns as available (true) on the affected Chrome version
A user is affected if Google Chrome version is below 148.0.7778.96 and the WebCodecs API is accessible in the browser environment.
