{"id":"CVE-2026-27602","aliases":["GHSA-wwv8-cqpr-vx3m","PYSEC-2026-2223"],"url":"https://o3.security/vulnerability/CVE-2026-27602","summary":"Modoboa has an OS Command Injection","details":"Modoboa is a mail hosting and management platform. Prior to version 2.7.1, `exec_cmd()` in `modoboa/lib/sysutils.py` always runs subprocess calls with `shell=True`. Since domain names flow directly into shell command strings without any sanitization, a Reseller or SuperAdmin can include shell metacharacters in a domain name to run arbitrary OS commands on the server. Version 2.7.1 patches the issue.","published":"2026-03-25T18:49:25.825Z","modified":"2026-08-07T11:50:49.804264923Z","cvss":{"score":7.2,"severity":"HIGH","vector":"CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:H"},"epss":null,"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"PyPI","name":"modoboa","fixedVersion":"2.7.1"}],"fix":{"url":"https://github.com/modoboa/modoboa/commit/27a7aa133d3608fe8c25ae39125d1012c333cbfa","label":"modoboa/modoboa@27a7aa1"},"references":[{"type":"WEB","url":"https://github.com/modoboa/modoboa/releases/tag/2.7.1"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/27xxx/CVE-2026-27602.json"},{"type":"ADVISORY","url":"https://github.com/modoboa/modoboa/security/advisories/GHSA-wwv8-cqpr-vx3m"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-27602"},{"type":"FIX","url":"https://github.com/modoboa/modoboa/commit/27a7aa133d3608fe8c25ae39125d1012c333cbfa"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-07T11:50:49.804264923Z"}}
