The number of apps is mostlikely to grow duetothefactthat a single vulnerability that enables hackers to perform destructive code when users open a booby-trapped image consistedof in a message or web page is present in potentially hundreds of apps.
This vulnerability, tracked as CVE-2023-4863, comesfrom in a extensively utilized code library understood as libwebp, which Google developed more than a years ago to render the then-new WebP graphics format.
