Updated

There is another related security vulnerability.

There's another related CVE (CVE-2023-5217) that is fixed in Chromium 117.0.5938.132. This one is triggered by WebCodecs API encoder usage, so a workaround for older versions is to disable the WebCodecs API (--disable-blink-features=WebCodecs).
