{"cve":"CVE-2026-47125","nvd":{"published":"2026-05-29T18:17:12.347","modified":"2026-07-22T06:10:00.170","status":"Deferred","description":"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.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","score":8.8},"cwes":["CWE-862"],"references":["https://github.com/getarcaneapp/arcane/security/advisories/GHSA-jpjh-jm2p-39hh"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:37:48.043517290+00:00"},"epss":{"cve":"CVE-2026-47125","score":0.00245,"percentile":0.15819,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-jpjh-jm2p-39hh","url":"https://osv.dev/vulnerability/GHSA-jpjh-jm2p-39hh","summary":"Arcane: Missing admin authorization on global variables endpoint","modified":"2026-06-25T23:11:16.872809587Z","packages":[{"ecosystem":"Go","name":"github.com/getarcaneapp/arcane/backend","purl":"pkg:golang/github.com/getarcaneapp/arcane/backend","ranges":["<1.19.2"],"fixed":["1.19.2"]}]},{"id":"GO-2026-5476","url":"https://osv.dev/vulnerability/GO-2026-5476","summary":"Arcane: Missing admin authorization on global variables endpoint in github.com/getarcaneapp/arcane/backend","modified":"2026-06-25T23:01:14.584016680Z","packages":[{"ecosystem":"Go","name":"github.com/getarcaneapp/arcane/backend","purl":"pkg:golang/github.com/getarcaneapp/arcane/backend","ranges":["<1.19.2"],"fixed":["1.19.2"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
