{"id":"CVE-2026-96626","state":"PUBLISHED","title":"Arcane: Container-registry credential exfiltration via URL repoint + test to attacker host","description":"Arcane is an interface for managing Docker containers, images, networks, and volumes. Prior to 2.5.0, UpdateRegistry and TestRegistry in backend/api/services/container_registry_service.go allow the registry URL to change while preserving the stored encrypted token. When a holder of registries:update and registries:test repoints a generic registry URL without supplying a replacement token, TestRegistry decrypts the preserved token and RegistryLogin sends it to the attacker-controlled host because normalizeRegistryServerAddressInternal does not restrict the destination. This exposes the stored container-registry PAT or password and can enable image access or tampering. This issue is fixed in version 2.5.0.","publishedAt":"2026-10-16T21:07:39.570Z","updatedAt":"2026-10-28T17:50:38.766Z","severity":{"score":8.5,"label":"High","version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:L/A:N","source":"GitHub_M"},"assigner":"GitHub_M","products":["getarcaneapp arcane"],"affected":[{"vendor":"getarcaneapp","product":"arcane","versions":[{"version":"< 2.5.0","status":"affected"}]}],"references":["https://github.com/getarcaneapp/arcane/security/advisories/GHSA-9pxc-cxp5-qp54","https://github.com/getarcaneapp/arcane/pull/3317","https://github.com/getarcaneapp/arcane/commit/fe31693634f48f295a7d77d091085b331cf9e915","https://github.com/getarcaneapp/arcane/releases/tag/backend/v2.5.0"],"weaknesses":["CWE-200","CWE-522"],"ingestedAt":"2026-10-29T20:13:43.249Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/96xxx/CVE-2026-96626.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-96626","state":"PUBLISHED","datePublished":"2026-10-16T21:07:39.570Z","dateUpdated":"2026-10-28T17:50:38.766Z","assignerShortName":"GitHub_M","assignerOrgId":"a0819718-46f1-4df5-94e2-005712e83aaa","dateReserved":"2026-09-23T14:35:50.129Z"},"containers":{"cna":{"title":"Arcane: Container-registry credential exfiltration via URL repoint + test to attacker host","descriptions":[{"lang":"en","value":"Arcane is an interface for managing Docker containers, images, networks, and volumes.
