{"id":"AZL-105326","summary":"CVE-2026-95521 affecting package rpm 4.18.2-2","details":"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.","modified":"2026-10-03T05:35:10Z","published":"2026-09-24T14:18:20Z","upstream":["CVE-2026-95521"],"references":[{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-95521"}],"affected":[{"package":{"name":"rpm","ecosystem":"Azure Linux:3","purl":"pkg:rpm/azure-linux/rpm"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"last_affected":"4.18.2-2"}]}],"database_specific":{"source":"https://github.com/microsoft/AzureLinuxVulnerabilityData/blob/main/osv/AZL-105326.json"}}],"schema_version":"1.9.0"}
