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2.5.0.","severity":"high","score":8.5,"published":"2026-10-16T21:07:39.570Z","modified":"2026-10-28T17:50:38.766Z","withdrawn":false,"knownExploited":false,"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"],"sources":[{"name":"CVE","id":"CVE-2026-96626","modified":"2026-10-28T17:50:38.766Z","url":"https://www.cve.org/CVERecord?id=CVE-2026-96626"}],"assessments":[{"source":"GitHub_M","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:L/A:N","score":8.5}],"sourceAffected":[],"kev":{"status":"not-listed","checkedAt":"2026-10-29T05:15:30.396Z"},"coverage":[{"source":"NVD","status":"not-checked"},{"source":"GHSA","status":"not-checked"},{"source":"EUVD","status":"not-checked"},{"source":"EPSS","status":"not-checked"}],"evidence":[]}
