CVE-2026-95519

Summary

A flaw was found in rpm. An attacker can supply a crafted manifest file that, when processed by a user or automation using rpm -q -p or similar manifest-processing flows, leads to arbitrary code execution. This occurs because manifest entries are unexpectedly macro-expanded before being opened, allowing embedded shell commands to run with the privileges of the rpm process. Successful exploitation can lead to a full compromise of confidentiality, integrity, and availability for the affected account.

Weaknesses

  • CWE-78: Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection')

Workarounds

To mitigate this issue, avoid querying untrusted files with rpm. When handling untrusted inputs, use the --nomanifest option to prevent macro expansion. For automation requiring manifest support, pre-validate entries to ensure only literal paths or globs are accepted and macro syntax is rejected.
