{"id":"JLSEC-2026-52","details":"Time-of-check Time-of-use (TOCTOU) race condition in pg_dump in PostgreSQL allows an object creator to execute arbitrary SQL functions as the user running pg_dump, which is often a superuser. The attack involves replacing another relation type with a view or foreign table. The attack requires waiting for pg_dump to start, but winning the race condition is trivial if the attacker retains an open transaction. Versions before PostgreSQL 16.4, 15.8, 14.13, 13.16, and 12.20 are affected.","modified":"2026-04-03T13:31:40.976065Z","published":"2026-04-03T13:27:15.647Z","upstream":["CVE-2024-7348"],"database_specific":{"license":"CC-BY-4.0","sources":[{"url":"https://services.nvd.nist.gov/rest/json/cves/2.0?cveId=CVE-2024-7348","imported":"2026-04-03T13:13:10.515Z","html_url":"https://nvd.nist.gov/vuln/detail/CVE-2024-7348","modified":"2024-11-21T09:51:20.720Z","published":"2024-08-08T13:15:14.007Z","id":"CVE-2024-7348"}]},"references":[{"type":"WEB","url":"https://www.postgresql.org/support/security/CVE-2024-7348/"},{"type":"WEB","url":"http://www.openwall.com/lists/oss-security/2024/08/11/1"},{"type":"WEB","url":"https://security.netapp.com/advisory/ntap-20240822-0002/"}],"affected":[{"package":{"name":"LibPQ_jll","ecosystem":"Julia","purl":"pkg:julia/LibPQ_jll?uuid=08be9ffa-1c94-5ee5-a977-46a84ec9b350"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0"},{"fixed":"16.8.0+0"}]}],"database_specific":{"source":"https://github.com/JuliaLang/SecurityAdvisories.jl/tree/generated/osv/2026/JLSEC-2026-52.json"}}],"schema_version":"1.7.5"}
