{"cve":"CVE-2026-45625","nvd":{"published":"2026-05-29T18:17:10.267","modified":"2026-07-21T15:10:00.103","status":"Deferred","description":"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. 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_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H","score":9.9},"cwes":["CWE-862"],"references":["https://github.com/getarcaneapp/arcane/security/advisories/GHSA-7h26-hg47-p9hx"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:37:48.043517290+00:00"},"epss":{"cve":"CVE-2026-45625","score":0.00387,"percentile":0.32869,"date":"2026-11-01"},"kev":null,"osv":[{"id":"GHSA-7h26-hg47-p9hx","url":"https://osv.dev/vulnerability/GHSA-7h26-hg47-p9hx","summary":"Arcane Backend: Missing admin authorization on git repository endpoints allows non-admin users to exfiltrate stored Git credentials and tamper with GitOps configs","modified":"2026-06-25T19:56:18.427757628Z","packages":[{"ecosystem":"Go","name":"github.com/getarcaneapp/arcane/backend","purl":"pkg:golang/github.com/getarcaneapp/arcane/backend","ranges":["<1.19.0"],"fixed":["1.19.0"]}]},{"id":"GO-2026-5220","url":"https://osv.dev/vulnerability/GO-2026-5220","summary":"Arcane Backend: Missing admin authorization on git repository endpoints allows non-admin users to exfiltrate stored Git credentials and tamper with GitOps configs in github.com/getarcaneapp/arcane/backend","modified":"2026-06-25T19:45:20.572306857Z","packages":[{"ecosystem":"Go","name":"github.com/getarcaneapp/arcane/backend","purl":"pkg:golang/github.com/getarcaneapp/arcane/backend","ranges":["<1.19.0"],"fixed":["1.19.0"]}]}],"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).
