{"id":"CVE-2026-45626","aliases":["GHSA-9mvm-4gwg-v8mp","GO-2026-5292"],"url":"https://o3.security/vulnerability/CVE-2026-45626","summary":"Arcane: OS Command Injection in Volume Browser ListDirectory via path query parameter","details":"Arcane is an interface for managing Docker containers, images, networks, and volumes. In 1.18.1 and earlier, GET /environments/{id}/volumes/{volumeName}/browse accepts a path query parameter that is passed to a shell command (sh -c \"find … | while …\") inside an Arcane helper container. The path sanitiser blocks ../ traversal but does not strip Bourne-shell metacharacters such as $() or backticks, and strconv.Quote only escapes Go string metacharacters, not shell substitution sequences. Any authenticated user with access to a browseable volume can execute arbitrary commands inside the helper container; command output is reflected back in the 500 error body.","published":"2026-05-29T17:10:22.582Z","modified":"2026-08-12T03:51:44.595690805Z","cvss":{"score":6.3,"severity":"MEDIUM","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:L/A:L"},"epss":{"score":0.0021,"percentile":0.11449,"asOf":"2026-08-14"},"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"Go","name":"github.com/getarcaneapp/arcane/backend","fixedVersion":null}],"fix":null,"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/45xxx/CVE-2026-45626.json"},{"type":"ADVISORY","url":"https://github.com/getarcaneapp/arcane/security/advisories/GHSA-9mvm-4gwg-v8mp"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-45626"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-12T03:51:44.595690805Z"}}
