Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-45626 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- github.com/getarcaneapp/arcane/backend (Go): affected all versions; no fix listed\n- github.com/getarcaneapp/arcane/backend (Go): affected all versions up to 1.18.1; no fix listed\n- github.com/getarcaneapp/arcane/backend (Go): affected all versions up to 1.18.1; no fix listed\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-2026-45626/ (Markdown: https://insights.sbomify.com/CVE-2026-45626/index.md)","id":"CVE-2026-45626","markdown":"https://insights.sbomify.com/CVE-2026-45626/index.md","name":"CVE-2026-45626","record":{"aliases":["GHSA-9mvm-4gwg-v8mp","GO-2026-5292"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"Docker management interface","requires_auth":"low_privilege","summary":"Authenticated users can execute arbitrary shell commands in the helper container via the volume browser path parameter due to insufficient input sanitization.","user_interaction":"not_required","vuln_class":"command_injection"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[],"cvss":{"score":6.3,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:L/A:L","version":"3.1"},"cwes":[{"id":"CWE-78","name":"Improper Neutralization of Special Elements used in an OS Command"}],"description":"Arcane is an interface for managing Docker containers, images, networks, and volumes. In 1.18.1 and earlier, GET /environments/{id}/volumes/{volumeName}/browse accepts a path query parameter that is passed to a shell command (sh -c \"find … | while …\") inside an Arcane helper container. The path sanitiser blocks ../ traversal but does not strip Bourne-shell metacharacters such as $() or backticks, and strconv.Quote only escapes Go string metacharacters, not shell substitution sequences.
