Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-120147 in the wild and no public exploit code.\nExposure: Only installations with a non-default setting turned on are exposed.\n\nAffected product: PostgreSQL. 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-2026-120147/ (Markdown: https://insights.sbomify.com/CVE-2026-120147/index.md)","id":"CVE-2026-120147","markdown":"https://insights.sbomify.com/CVE-2026-120147/index.md","name":"CVE-2026-120147","record":{"aliases":["ALPINE-CVE-2026-120147","DEBIAN-CVE-2026-120147","ECHO-9501-1724-f6ac","GHSA-63j6-rm8q-mhqx"],"analysis":{"component_type":"database","exploitable_when_present":false,"fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"yes","non_default_config":true,"product_category":"relational database","requires_auth":"low_privilege","requires_specific_call":false,"summary":"An object creator can execute code as the database OS user via reentrant dblink use-after-free in PostgreSQL; PostgreSQL administrators should care.","user_interaction":"not_required","vuln_class":"use_after_free","vulnerable_functions":[]},"analysis_generated_by":"sbomify/insights-2b-fp8","assigner":"PostgreSQL","cpe":[],"cvss":{"score":8.8,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-416","name":"Use After Free"}],"description":"Use after free in the PostgreSQL dblink extension allows an object creator to execute arbitrary code as the operating system user running the database, via type conversion code that re-enters dblink and closes a connection whose results an outer dblink call is reading.
