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

7.0 HighFix available

CVE-2026-44604 is a high vulnerability (CVSS 7.0) in Red Hat Enterprise Linux 10, published May 28, 2026. No source lists public exploit code. EPSS puts the chance of exploitation in the next 30 days at 0.57%, the 47th percentile. Fixed in python3-rpm 0:6.0.1-6.1.hum1.

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.
