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.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H","score":7.8},"cwes":["CWE-78"],"references":["https://access.redhat.com/errata/RHSA-2026:82378","https://access.redhat.com/security/cve/CVE-2026-84837","https://bugzilla.redhat.com/show_bug.cgi?id=2478408"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:50:50.842544443+00:00"},"epss":{"cve":"CVE-2026-84837","score":0.01303,"percentile":0.70289,"date":"2026-10-25"},"kev":null,"osv":[],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
