Snyk has a proof-of-concept or detailed explanation of how to exploit this vulnerability.
The probability is the direct output of the EPSS model, and conveys an overall sense of the threat of exploitation in the wild. The percentile measures the EPSS probability relative to all known EPSS scores. Note: This data is updated daily, relying on the latest available EPSS model version. Check out the EPSS documentation for more details.

Start learningThere is no fixed version for MediaBrowser.Server.Core
.
MediaBrowser.Server.Core is a package that contains core components required to build plugins for Emby Server.
Affected versions of this package are vulnerable to Access Restriction Bypass. In Emby Server on Windows there are two arbitrary file read vulnerabilities.
The first is via /Videos/Id/hls/PlaylistId/SegmentId.SegmentContainer
. It is possible to set the {SegmentId}.{SegmentContainer}
part of the route to an absolute path using the Windows path separator \
(%5C
when URL encoded).
The PlaylistId
doesn’t matter, but a prerequisite is a knowledge of the Id
- a GUID of an existing media file. The Id
can be leaked by any authenticated user as it is exposed in server responses.
Additionally, both the /Images/Ratings/{theme}/{name}
and /Images/MediaInfo/{theme}/{name}
routes allow unauthenticated arbitrary image file read on Windows. It is possible to set the {theme}
or {name}
part of the route to a relative or absolute path using the Windows path separator ``` (%5C
when URL encoded). The route automatically appends the following allowed extensions, so it is only possible to read image files: .png
, .jpg
, .jpeg
, .tbn
, .gif
