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-2026-16503 in the wild and no public exploit code.\n\nAffected product: VPS.org Supabase template. 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-2026-16503/ (Markdown: https://insights.sbomify.com/CVE-2026-16503/index.md)","id":"CVE-2026-16503","markdown":"https://insights.sbomify.com/CVE-2026-16503/index.md","name":"CVE-2026-16503","record":{"aliases":["GHSA-j3fc-fx73-7qv7"],"analysis":{"component_type":"container_or_infrastructure","fix_type":"configuration_change","impacts":["data_read","data_modify"],"network_reachable":"yes","non_default_config":false,"product_category":"Supabase deployment template","requires_auth":"none","summary":"Attackers can access the database due to default credentials and exposed ports, requiring administrators to secure the deployment configuration.","user_interaction":"not_required","vuln_class":"misconfiguration"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"certcc","cpe":[],"cvss":{"score":9.1,"severity":"critical","source":"cisa-adp","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:N","version":"3.1"},"cwes":[{"id":"CWE-1393","name":"Use of Default Password"},{"id":"CWE-1327","name":"Binding to an Unrestricted IP Address"},{"id":"CWE-1188","name":"Initialization of a Resource with an Insecure Default"}],"description":"Deployment of the VPS.org one-click Supabase template deploys a PostgreSQL instance that is published on all interfaces (0.0.0.0:5432) with a default database password set to \"postgres\".
