What is CVE-2026-95521?

A command injection vulnerability has been identified in RPM that allows untrusted source RPM files to execute arbitrary commands. If a source or spec file basename includes a %() macro, RPM executes an attacker-controlled shell command through popen() during the relocation of the source file list. This can occur when a user installs or rebuilds an untrusted .src.rpm file, and is particularly concerning as it can be exploited by non-root users, leading to unauthorized command execution.
