{"id":"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.","aliases":["GHSA-9mvm-4gwg-v8mp","GO-2026-5292"],"modified":"2026-07-08T08:13:29.715716082Z","published":"2026-05-29T17:10:22.582Z","database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/45xxx/CVE-2026-45626.json","cwe_ids":["CWE-78"],"cna_assigner":"GitHub_M"},"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"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/getarcaneapp/arcane","events":[{"introduced":"0"},{"last_affected":"6a3b782d2f5750f3f59b870cf9a2cbfe16874cac"}],"database_specific":{"source":"AFFECTED_FIELD","extracted_events":[{"introduced":"0"},{"last_affected":"1.18.1"}]}}],"versions":["v1.18.1","types/v1.18.1","cli/v1.18.1","backend/v1.18.1","v1.18.0","types/v1.18.0","cli/v1.18.0","backend/v1.18.0","v1.17.4","types/v1.17.4","cli/v1.17.4","backend/v1.17.4","v1.17.3","types/v1.17.3","cli/v1.17.3","backend/v1.17.3","v1.17.2","types/v1.17.2","cli/v1.17.2","backend/v1.17.2","v1.17.1","types/v1.17.1","cli/v1.17.1","backend/v1.17.1","v1.17.0","types/v1.17.0","cli/v1.17.0","backend/v1.17.0","v1.16.3","types/v1.16.3","cli/v1.16.3","backend/v1.16.3","v1.16.2","types/v1.16.2","cli/v1.16.2","backend/v1.16.2","v1.16.1","types/v1.16.1","cli/v1.16.1","backend/v1.16.1","v1.16.0","types/v1.16.0","cli/v1.16.0","backend/v1.16.0","v1.15.3","types/v1.15.3","cli/v1.15.3","backend/v1.15.3","v1.15.2","types/v1.15.2","cli/v1.15.2","v1.15.1","types/v1.15.1","cli/v1.15.1","v1.15.0","types/v1.15.0","cli/v1.15.0","v1.14.1","v1.14.0","v1.13.2","v1.13.1","v1.13.0","v1.12.2","v1.12.1","v1.12.0","v1.11.3","v1.11.2","v1.11.1","v1.11.0","v1.10.1","v1.10.0","v1.9.0","v1.8.1","v1.8.0","v1.7.1","v1.7.0","v1.6.0","v1.5.2","v1.5.1","v1.5.0","v1.4.0","v1.3.0","v1.2.2","v1.2.1","v1.2.0","v1.1.0","v1.0.2","v1.0.1","v1.0.0","v0.15.1","v0.15.0","v0.14.0","v0.13.1","v0.13.0","v0.12.0","v0.11.1","v0.11.0","v0.10.0","v0.9.2","v0.9.1","v0.9.0","v0.8.0","v0.7.1","v0.7.0","v0.6.0","v0.5.0","v0.4.1","v0.4.0","v0.3.0","v0.2.0","v0.1.1","v0.1.0"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-45626.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:L/A:L"}]}
