This command injection vulnerability allows a local attacker to execute arbitrary commands. This occurs when rpmuncompress processes a specially crafted archive filename containing shell metacharacters, which are not properly escaped before being passed to shell command strings. Successful exploitation requires user interaction, where a user or automated workflow invokes rpmuncompress on the malicious file, leading to high impact on the confidentiality, integrity, and availability of data accessible to the invoking user.","epss":{"date":"2026-11-02","percentile":0.65806,"score":0.01105},"exploits":[],"kev":null,"metrics":[{"score":7.8,"severity":"high","source":"CNA: redhat","vector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H","version":"3.1"}],"modifiedAt":1793688667406,"publishedAt":1788361982577,"references":[{"source":"CNA: redhat","tags":["vendor-advisory","x_refsource_REDHAT"],"url":"https://access.redhat.com/errata/RHSA-2026:82378"},{"source":"CNA: redhat","tags":["vdb-entry","x_refsource_REDHAT"],"url":"https://access.redhat.com/security/cve/CVE-2026-84838"},{"source":"CNA: redhat","tags":["issue-tracking","x_refsource_REDHAT"],"url":"https://bugzilla.redhat.com/show_bug.cgi?id=2462222"}],"remediation":[{"kind":"workaround","source":"CNA: redhat","text":"To mitigate this issue, avoid processing untrusted archive filenames with `rpmuncompress` or any workflows that invoke `%{__rpmuncompress}`.
