Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-96538 in the wild and no public exploit code.\n\nAffected product: EnterpriseDB WarehousePG. 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-2026-96538/ (Markdown: https://insights.sbomify.com/CVE-2026-96538/index.md)","id":"CVE-2026-96538","markdown":"https://insights.sbomify.com/CVE-2026-96538/index.md","name":"CVE-2026-96538","record":{"aliases":["GHSA-gq88-v7m3-v3c5"],"analysis":{"component_type":"database","fix_type":"upgrade","impacts":["code_execution","privilege_escalation"],"network_reachable":"yes","non_default_config":false,"product_category":"WarehousePG database","requires_auth":"low_privilege","summary":"Non-superusers can exploit missing authorization in file functions to modify configuration files, leading to arbitrary code execution as the postgres user.","user_interaction":"not_required","vuln_class":"missing_authorization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"EDB","cpe":[],"cvss":{"score":8.7,"severity":"high","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-862","name":"Missing Authorization"}],"description":"WarehousePG (WHPG) 7.x before 7.6.0-WHPG is affected by a missing authorization vulnerability (CWE-862) in the built-in server-side file functions pg_file_write(text,text,bool), pg_file_rename(text,text,text), pg_file_unlink(text), and pg_logdir_ls(). These functions are executable by any authenticated database role with no GRANT required, because the REVOKE that contrib/adminpack applies to the equivalent functions was never carried over to WHPG core when their catalog entries were repointed to the ungated adminpack-derived implementations as part of Greenplum's merge to a PostgreSQL 12 base. A non-superuser can use pg_file_write, pg_file_rename, and pg_file_unlink to create, overwrite (append), rename, and delete files under the data and log directories, and can use pg_logdir_ls() to enumerate log file names. Because postgresql.auto.conf resides in the data directory, a non-superuser can append configuration directives such as shared_preload_libraries or archive_command to it, resulting in arbitrary code execution as the postgres operating system user on the next server restart or configuration reload. WarehousePG 6.x is not affected, as the equivalent functions there enforce a superuser check internally.","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":"WarehousePG pg_file_write/pg_file_rename/pg_file_unlink/pg_logdir_ls privilege escalation","id":"CVE-2026-96538","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"missing_authorization","year":"2026"},"n_packages":0,"n_references":2,"next":{"headline":"WordPress Ultimate Member plugin \u003c= 2.13.1 - Privilege Escalation vulnerability","id":"CVE-2026-96539"},"packages":[],"prev":{"headline":"Tutor LMS \u003c 4.1.1 - Unauthenticated Tutor Page Force-Publish and Content Overwrite","id":"CVE-2026-96537"},"products":["WarehousePG"],"published":"2026-09-28","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"no","exploitation":"none","technical_impact":"total"},"state":"PUBLISHED","updated":"2026-09-28","vendors":["EnterpriseDB"]},"summary":"Non-superusers can exploit missing authorization in file functions to modify configuration files, leading to arbitrary code execution as the postgres user.","url":"https://insights.sbomify.com/CVE-2026-96538/"}
