Overview

CVE-2026-96626 is a high-severity vulnerability. It was published on October 16, 2026 and has a CVSS 3.1 base score of 8.5 (HIGH).

This vulnerability has a CVSS 3.1 base score of 8.5, rated HIGH. It can be exploited remotely over the network. Some level of privileges is required for exploitation.

Technical 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.

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
