Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-120143 in the wild and no public exploit code.\nExposure: An affected version is exposed as installed. No special setting or call is needed.\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-2026-120143/ (Markdown: https://insights.sbomify.com/CVE-2026-120143/index.md)","id":"CVE-2026-120143","markdown":"https://insights.sbomify.com/CVE-2026-120143/index.md","name":"CVE-2026-120143","record":{"aliases":["ALPINE-CVE-2026-120143","DEBIAN-CVE-2026-120143","ECHO-6923-a61b-d02a","GHSA-x9hr-cq8v-94x6"],"analysis":{"component_type":"database","exploitable_when_present":false,"fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"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 a cursor over a PostgreSQL transition table in trigger functions.","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 PostgreSQL trigger functions allows an object creator to execute arbitrary code as the operating system user running the database, via a cursor over a transition table.
