CVE-2026-84837
Rpm: command injection in `rpmbuild -t*` (`gettarspec`) via unescaped tarball path
CVSS Score

EPSS Score

EPSS Percentile
67th
A flaw was found in rpm. An attacker can exploit a command injection vulnerability by influencing the path or filename of a tarball processed by `rpmbuild -t*` to include shell metacharacters. This is particularly relevant in automated build or continuous integration (CI) workflows that ingest externally supplied artifact names. Successful exploitation allows for arbitrary command execution with the privileges of the build user, which could lead to information disclosure or disruption of the build environment.
