blueprintUE Self-Hosted Edition before 4.3.6 contains an iframe injection vulnerability that allows authenticated users to embed arbitrary third-party content by abusing the PeerTube video URL matcher in BlueprintService::findVideoProvider(). Attackers can set a blueprint video URL on an attacker-controlled host, which site.js loads in an unsandboxed iframe after consent, framing fake login forms or malware downloads.

——2When tarfile or zipfile command line interface (CLI) is used to
decompress an archive, a Python script shadowing the stdlib can be
created. Then if an error occurs during decompressing the next file,
the newly created Python script is executed. This is especially true
if the created Python is called traceback.py. The problem is that
Python adds the current directory to sys.path when python -m MODULE is
run, and the archive is also decompressed in the current directory.
The fix removes sys.path[0] in gzip, tarfile and zipfile command line
interface to prevent shadowing standard library modules from extracted
files.21h
