"Although initially the vulnerability CVE-2023-4863 was assigned to Google Chrome, it really affects the library LibWebP. That’s why on September 25th, a new dedicated CVE identifier was created, the CVE-2023-5217. It is the same vulnerability but assigned to the library instead of Google Chrome browser exclusively. Also, Google assigned the highest criticality possible to this new identifier, with a CVSS3.1 score of 10."
