CVE-2026-44604 · Rpm: command injection in rpmuncompress dountar() via unescaped archive top-level directory name in popen() shell command

This page contains facts from public vulnerability sources. Check the original advisory before updating.

A command injection vulnerability was discovered in the `rpmuncompress` utility of RPM. When extracting certain archive formats (ZIP, 7z, GEM) to a specified destination directory, the tool inserts the archive's top-level folder name into a shell command without properly sanitizing it. A specially crafted archive containing shell metacharacters in its folder name can execute arbitrary commands as the user running the extraction.
