CVE-2026-95521

high

Description

A command injection flaw was found in rpm. Installing or rebuilding a source RPM whose source or spec file basenames contain a %() macro construct causes rpm to execute an attacker-controlled shell command via popen() while relocating the source file list. This allows arbitrary command execution as the invoking (typically non-root) user, simply by installing, rebuilding, or otherwise processing an untrusted .src.rpm.
