8.8 highEPSS 0.6%

High (8.8) in mozilla firefox. EPSS 0.6% chance of exploitation in the next 30 days.

If temporary "one-time" permissions, such as the ability to use the Camera, were granted to a document loaded using a file: URL, that permission persisted in that tab for all other documents loaded from a file: URL. This is potentially dangerous if the local files came from different sources, such as in a download directory. This vulnerability affects Firefox < 111.
