Description
A command injection vulnerability exists in rpm when processing tarball paths or filenames via the `rpmbuild -t*` command. An attacker who can control these inputs in automated build or CI workflows may execute arbitrary commands with the build user's privileges. This could lead to information disclosure or disruption of the build environment.

Technical Analysis
CVE-2026-84837 describes a command injection flaw in rpm. The vulnerability arises when the path or filename of a tarball processed by `rpmbuild -t*` includes shell metacharacters, allowing an attacker to inject commands. This is especially relevant in automated build or continuous integration environments that ingest externally supplied artifact names. Exploitation permits arbitrary command execution with the privileges of the build user, potentially causing information disclosure or build disruption.
Potential Impact
Successful exploitation allows arbitrary command execution with the privileges of the build user. This can lead to information disclosure and disruption of the build environment. The vulnerability affects the integrity and confidentiality of the build process.
