Py7zr is a Python library for reading and writing 7z archive files, presenting a focused, supply-chain-embedded component where vulnerabilities can propagate to any downstream application that parses untrusted archives. The library's disclosed weakness profile centers on path-traversal conditions during archive extraction, a classic hazard in archive handlers where insufficient pathname validation allows malicious entries to write outside their intended directory. Live severity, exploitation, and exposure counts are shown alongside this summary.
