Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-45625 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- github.com/getarcaneapp/arcane/backend (Go): affected all versions; fixed in 1.19.0\n- github.com/getarcaneapp/arcane/backend (Go): affected all versions; fixed in 1.19.0\n- github.com/getarcaneapp/arcane/backend (Go): affected all versions; fixed in 1.19.0\n\nTask:\n1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.\n2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.\n3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.\n4. Run the tests and summarise what changed and why.\n5. If nothing in the project is affected, say so and change nothing.\n\nReference: https://insights.sbomify.com/CVE-2026-45625/ (Markdown: https://insights.sbomify.com/CVE-2026-45625/index.md)","id":"CVE-2026-45625","markdown":"https://insights.sbomify.com/CVE-2026-45625/index.md","name":"CVE-2026-45625","record":{"aliases":["GHSA-7h26-hg47-p9hx","GO-2026-5220"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["data_read","data_modify"],"network_reachable":"yes","non_default_config":false,"product_category":"Docker management interface","requires_auth":"low_privilege","summary":"Non-admin users can access Git repository endpoints to exfiltrate stored credentials and tamper with GitOps configurations due to missing authorization checks.","user_interaction":"not_required","vuln_class":"missing_authorization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[],"cvss":{"score":9.9,"severity":"critical","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-862","name":"Missing Authorization"}],"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.
