A severe browser security flaw, tacked as CVE-2023-4863 and then CVE-2023-5129, has led to emergency updates in Google Chrome, Microsoft Edge, Mozilla’s Firefox, and Apple’s Safari browsers.
The vulnerability, in the libwebp image format, which was made by Google to provide better image compression than e.g., JPEG or PNG, leaves any program using it, such as browsers, vulnerable to attack.
The advice is to check and make sure that you have the most up-to-date bowser version. For example, in Chrome, click on the three dots (top right), then on Help > About Google Chrome to reveal the version number.
