CVE-2026-95519
Rpm: code execution via macro expansion of manifest entries in `rpmgi` (`-q -p` / verify manifest flows)
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.
Fixes and workarounds
Workaround
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.
