CVE-2026-44604 Details
Description
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.
A command injection vulnerability exists in the RPM utility's rpmuncompress command, specifically when extracting certain archive formats such as ZIP, 7z, and GEM. The vulnerability arises because the tool improperly sanitizes the top-level folder name of the archive before inserting it into a shell command. This flaw allows a specially crafted archive with shell metacharacters in its folder name to execute arbitrary commands as the user performing the extraction. The issue is confirmed in RPM version 6.0.1-5.1.hum1 and likely affects other versions with the same vulnerability structure.
Avoid processing untrusted archives with the rpmuncompress command, especially through workflows that use '%setup' or '%autosetup -C', as these can trigger the vulnerable extraction path. Treat source archives as trusted inputs in build and continuous integration pipelines.
