CVE-2026-45625

Estado: AplazadaCrítica (9.9)—

Arcane is an interface for managing Docker containers, images, networks, and volumes. Prior to 1.19.0, Arcane's huma-based REST API exposes nine endpoints under /api/customize/git-repositories and /api/git-repositories/sync for managing GitOps source repositories and their stored credentials.

Leer descripción completaMostrar menos

Eight of those endpoints (list, create, get, update, delete, test, listBranches, browseFiles) never call the checkAdmin(ctx) helper that every other admin-managed resource (container registries, environments, users, API keys, swarm, settings, system, notifications, events) uses, and the huma authentication middleware deliberately enforces only authentication, not the admin role. As a result, any logged-in user with the default user role can list, create, modify, delete, and test git repository configurations. By repointing an existing repository's URL to an attacker-controlled host while omitting the token/sshKey fields (which UpdateRepository only rewrites when explicitly supplied), the attacker causes Arcane to decrypt the legitimate PAT/SSH key on its next /test, /branches, or /files call and present it as HTTP Basic auth (or SSH key auth) to the attacker's host — producing a one-step exfiltration of plaintext Git credentials. This vulnerability is fixed in 1.19.0.

CVSS

Probabilidad de explotación (EPSS)

EPSS (Exploit Prediction Scoring System, de FIRST) estima la probabilidad de que una vulnerabilidad sea explotada en 30 días. Complementa a CVSS (impacto) y a CISA KEV (explotación confirmada).

      "value": "Arcane es una interfaz para gestionar contenedores Docker, imágenes, redes y volúmenes. Antes de la versión 1.19.0, la API REST de Arcane basada en huma expone nueve puntos finales bajo /api/customize/git-repositories y /api/git-repositories/sync para gestionar repositorios de origen GitOps y sus credenciales almacenadas. Ocho de esos puntos finales (list, create, get, update, delete, test, listBranches, browseFiles) nunca llaman a la función auxiliar checkAdmin(ctx) que utiliza cualquier otro recurso gestionado por el administrador (registros de contenedores, entornos, usuarios, claves de API, swarm, configuraciones, sistema, notificaciones, eventos), y el middleware de autenticación de huma aplica deliberadamente solo la autenticación, no el rol de administrador. Como resultado, cualquier usuario con sesión iniciada con el rol de usuario predeterminado puede listar, crear, modificar, eliminar y probar configuraciones de repositorios git. Al redirigir la URL de un repositorio existente a un host controlado por un atacante, omitiendo los campos token/sshKey (que UpdateRepository solo reescribe cuando se suministran explícitamente), el atacante provoca que Arcane descifre la clave PAT/SSH legítima en su siguiente llamada a /test, /branches o /files y la presente como autenticación básica HTTP (o autenticación por clave SSH) al host del atacante, produciendo una exfiltración en un solo paso de credenciales Git en texto plano. Esta vulnerabilidad está corregida en la versión 1.19.0."
