SCA: security update for github.com/getarcaneapp/arcane/backend (GHSA-jpjh-jm2p-39hh)

high Tenable Self-Hosted Container Security Plugin ID 442330

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

- Arcane is an interface for managing Docker containers, images, networks, and volumes. Prior to 1.19.2, the
PUT /api/environments/{id}/templates/variables endpoint, which writes the system-wide .env.global file
used for variable substitution in every project's compose file, is missing an admin authorization check.
Any authenticated non-admin user can call this endpoint with their bearer token or API key and overwrite
the global environment variables that are merged into every project deployment. By overriding values like
REGISTRY, IMAGE, DATABASE_URL, or SECRET_KEY that other users reference via ${VAR} in compose files, an
attacker can redirect image pulls to attacker-controlled registries (supply-chain RCE on the Docker host),
exfiltrate database credentials, or disrupt all projects. This vulnerability is fixed in 1.19.2.
(CVE-2026-47125)

Solution

Update the github.com/getarcaneapp/arcane/backend library and its related packages to version 1.19.2 or later.
