MEDIUM 6.5EPSS 0.96%

Does this matter?

Lower severity and a low EPSS score (0.96%). Track it; it rarely justifies an emergency change on its own.

Description

The `VideoBridge` allowed any content process to use textures produced by remote decoders. This could be abused to escape the sandbox. This vulnerability affects Firefox ESR < 115.6, Thunderbird < 115.6, and Firefox < 121.
