CVE-2026-95521
Rpm: rpm: shell command injection via macro expansion of source/spec file basenames when installing a source rpm
Monitor this CVE ↗Full CVE monitoring on Pro and Business
What happened?
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.

Version information comes from the source record and can include unaffected products and exceptions. Distribution packages may contain backported fixes: an older upstream version alone does not prove a server is affected.
Is it being exploited?
This CVE was not listed in the CISA catalogue at our last retrieval. This does not establish that exploitation is absent.
How to respond
- Confirm the product, installed package version, and any configuration requirements in the vendor advisory.
- Follow the vendor’s remediation or workaround guidance in the references below. Structured fixed-version data is unavailable here; the publisher’s description may include a fix or workaround.
- Restart affected services if required, then verify the running version. Known exploitation may warrant investigation as well as patching.
