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-2021-38140 in the wild and no public exploit code.\n\nAffected product: n/a. 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-2021-38140/ (Markdown: https://insights.sbomify.com/CVE-2021-38140/index.md)","id":"CVE-2021-38140","markdown":"https://insights.sbomify.com/CVE-2021-38140/index.md","name":"CVE-2021-38140","record":{"aliases":["GHSA-4fj7-2258-8pjp"],"analysis":{"component_type":"database","fix_type":"upgrade","impacts":["privilege_escalation"],"network_reachable":"yes","non_default_config":false,"product_category":"PostgreSQL extension","requires_auth":"none","summary":"A privilege escalation vulnerability in the PostgreSQL set_user extension allows attackers to regain original privileges after switching users.","user_interaction":"not_required","vuln_class":"privilege_escalation"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"set_user","vendor":"set_user_project"}],"cvss":{"score":9.8,"severity":"critical","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-269","name":"Improper Privilege Management"}],"description":"The set_user extension module before 2.0.1 for PostgreSQL allows a potential privilege escalation using RESET SESSION AUTHORIZATION after set_user().","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":false,"headline":"Privilege escalation in n/a","id":"CVE-2021-38140","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"privilege_escalation","year":"2021"},"n_packages":0,"n_references":2,"next":{"headline":"Security feature bypass in n/a","id":"CVE-2021-38142"},"packages":[],"prev":{"headline":"Cross-site scripting in n/a","id":"CVE-2021-38138"},"products":["n/a"],"published":"2021-08-10","related":[{"cvss_score":9.8,"headline":"The set_user extension module before 3.0.0 for PostgreSQL allows ProcessUtility_hook bypass via set_config.","id":"CVE-2021-41558","kev_date_added":null,"published":"2021-09-27"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"US public information, NVD API terms","name":"NVD"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-08-04","vendors":["n/a"]},"summary":"A privilege escalation vulnerability in the PostgreSQL set_user extension allows attackers to regain original privileges after switching users.","url":"https://insights.sbomify.com/CVE-2021-38140/"}
