{"id":"CVE-2026-96626","published":"2026-10-16T22:18:58.070","lastModified":"2026-10-16T22:18:58.193","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.","cvssScore":8.5,"cvssSeverity":"HIGH","cvssVector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:L/A:N","cwes":["CWE-200","CWE-522"],"vendors":[],"products":[],"references":[{"url":"https://github.com/getarcaneapp/arcane/commit/fe31693634f48f295a7d77d091085b331cf9e915","tags":[]},{"url":"https://github.com/getarcaneapp/arcane/pull/3317","tags":[]},{"url":"https://github.com/getarcaneapp/arcane/releases/tag/backend/v2.5.0","tags":[]},{"url":"https://github.com/getarcaneapp/arcane/security/advisories/GHSA-9pxc-cxp5-qp54","tags":[]}],"exploitRefs":[{"url":"https://github.com/getarcaneapp/arcane/commit/fe31693634f48f295a7d77d091085b331cf9e915","tags":[]},{"url":"https://github.com/getarcaneapp/arcane/pull/3317","tags":[]},{"url":"https://github.com/getarcaneapp/arcane/releases/tag/backend/v2.5.0","tags":[]},{"url":"https://github.com/getarcaneapp/arcane/security/advisories/GHSA-9pxc-cxp5-qp54","tags":[]}],"hasPoc":true,"ai":null}
