An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2026-6475 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- postgresql (Bitnami): affected all versions; fixed in 14.23.0, 15.18.0, 16.14.0, 17.10.0, 18.4.0\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-2026-6475/ (Markdown: https://insights.sbomify.com/CVE-2026-6475/index.md)","id":"CVE-2026-6475","markdown":"https://insights.sbomify.com/CVE-2026-6475/index.md","name":"CVE-2026-6475","record":{"aliases":["ALPINE-CVE-2026-6475","AZL-86828","BELL-CVE-2026-6475","BIT-postgresql-2026-6475","CLSA-2026-1788193166","DEBIAN-CVE-2026-6475","ECHO-848c-5472-d56d","GHSA-7h2q-899j-9636","JLSEC-2026-603","MINI-3r2q-5c95-rhc7","MINI-958x-fmvr-62x6","MINI-9vwq-hh9w-r747","MINI-cxvx-g5cx-9pv7","MINI-mggv-f2q2-q5mw","MINI-xrgc-48fx-wh2f","UBUNTU-CVE-2026-6475"],"analysis":{"component_type":"database","fix_type":"upgrade","impacts":["privilege_escalation","code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"PostgreSQL database","requires_auth":"none","summary":"An origin superuser can overwrite local files via symlink following in pg_basebackup or pg_rewind, potentially hijacking the OS account.","user_interaction":"required","vuln_class":"path_traversal"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"PostgreSQL","cpe":[{"product":"postgresql","vendor":"postgresql"}],"cvss":{"score":8.8,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-61","name":"UNIX Symbolic Link (Symlink) Following"}],"description":"Symlink following in PostgreSQL pg_basebackup plain format and in pg_rewind allows an origin superuser to overwrite local files, e.g. /var/lib/postgres/.bashrc, that hijack the operating system account.  It will remain the case that starting the server after these commands implicitly trusts the origin superuser, due to features like shared_preload_libraries.  Hence, the attack has practical implications only if one takes relevant action between these commands and server start, like moving the files to a different VM or snapshotting the VM.
