Description (CNA)
Malcolm is a network traffic analysis tool suite. Prior to version 26.07.0, `safe-extract.py` protects file extraction with libarchive's secure flags, but creates directory entries with a raw `os.makedirs(os.path.join(dest, entry.pathname))` that has no traversal protection. An uploaded malicious archive containing a directory entry with a `../` sequence or an absolute path causes the filebeat processing container to create directories outside the intended extraction directory. Version 26.07.0 fixes the issue.
