A local attacker can exploit this vulnerability by placing a maliciously named modulefile in a location visible to the victim's `MODULEPATH`. When the victim uses Bash completion for `module` or `ml` commands, the malicious module name, containing shell metacharacters, is evaluated as a command. This can lead to arbitrary command execution in the completing user's shell, impacting their confidentiality, integrity, and availability.","epss":{"date":"2026-11-05","percentile":0.1393,"score":0.0023},"exploits":[{"kind":"exploit","source":"ADP: CISA-ADP","url":"https://github.com/envmodules/modules/security/advisories/GHSA-8hrw-p88g-qhmg"}],"kev":null,"metrics":[{"score":7.3,"severity":"high","source":"CNA: redhat","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:R/S:U/C:H/I:H/A:H","version":"3.1"}],"modifiedAt":1793927262923,"publishedAt":1789484913907,"references":[{"source":"CNA: redhat","tags":["vendor-advisory","x_refsource_REDHAT"],"url":"https://access.redhat.com/errata/RHSA-2026:64766"},{"source":"CNA: redhat","tags":["vendor-advisory","x_refsource_REDHAT"],"url":"https://access.redhat.com/errata/RHSA-2026:80664"},{"source":"CNA: redhat","tags":["vendor-advisory","x_refsource_REDHAT"],"url":"https://access.redhat.com/errata/RHSA-2026:82919"},{"source":"CNA: redhat","tags":["vendor-advisory","x_refsource_REDHAT"],"url":"https://access.redhat.com/errata/RHSA-2026:84594"},{"source":"CNA: redhat","tags":["vdb-entry","x_refsource_REDHAT"],"url":"https://access.redhat.com/security/cve/CVE-2026-85013"},{"source":"CNA: redhat","tags":["issue-tracking","x_refsource_REDHAT"],"url":"https://bugzilla.redhat.com/show_bug.cgi?id=2465635"},{"source":"CNA: redhat","tags":[],"url":"https://github.com/envmodules/modules/security/advisories/GHSA-8hrw-p88g-qhmg"},{"source":"ADP: CISA-ADP","tags":["exploit"],"url":"https://github.com/envmodules/modules/security/advisories/GHSA-8hrw-p88g-qhmg"}],"remediation":[{"kind":"workaround","source":"CNA: redhat","text":"To mitigate this issue, avoid enabling Bash completion for `module` and `ml` in environments where untrusted users can influence `MODULEPATH`.
