An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-86117 in the wild and no public exploit code.\n\nAffected product: coollabsio coolify. No package-level version data is available, so check the vendor advisory linked from the reference page.\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-2026-86117/ (Markdown: https://insights.sbomify.com/CVE-2026-86117/index.md)","id":"CVE-2026-86117","markdown":"https://insights.sbomify.com/CVE-2026-86117/index.md","name":"CVE-2026-86117","record":{"aliases":["GHSA-rchm-727g-v36m"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["account_takeover"],"network_reachable":"yes","non_default_config":false,"product_category":"Coolify PaaS","requires_auth":"none","summary":"Attackers can hijack user accounts by registering their email on an OAuth provider, bypassing authentication and 2FA in Coolify.","user_interaction":"not_required","vuln_class":"auth_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"VulnCheck","cpe":[],"cvss":{"score":9.2,"severity":"critical","source":"cna","vector":"CVSS:4.0/AV:N/AC:H/AT:P/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-287","name":"Improper Authentication"}],"description":"Coolify through 4.3.17 contains an authentication bypass vulnerability in the OAuth callback handler that signs users into existing accounts based solely on email address without verifying provider assertions or binding OAuth identities.
