{"id":"JLSEC-2026-26","details":"A flaw was found in PostgreSQL versions before 13.1, before 12.5, before 11.10, before 10.15, before 9.6.20 and before 9.5.24. If a client application that creates additional database connections only reuses the basic connection parameters while dropping security-relevant parameters, an opportunity for a man-in-the-middle attack, or the ability to observe clear-text transmissions, could exist. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability.","modified":"2026-04-03T13:30:35.398621Z","published":"2026-04-03T13:27:15.647Z","upstream":["CVE-2020-25694"],"database_specific":{"license":"CC-BY-4.0","sources":[{"url":"https://services.nvd.nist.gov/rest/json/cves/2.0?cveId=CVE-2020-25694","id":"CVE-2020-25694","imported":"2026-04-03T13:13:09.665Z","published":"2020-11-16T01:15:12.670Z","modified":"2024-11-21T05:18:29.610Z","html_url":"https://nvd.nist.gov/vuln/detail/CVE-2020-25694"}]},"references":[{"type":"WEB","url":"https://bugzilla.redhat.com/show_bug.cgi?id=1894423"},{"type":"WEB","url":"https://lists.debian.org/debian-lts-announce/2020/12/msg00005.html"},{"type":"WEB","url":"https://security.gentoo.org/glsa/202012-07"},{"type":"WEB","url":"https://security.netapp.com/advisory/ntap-20201202-0003/"},{"type":"WEB","url":"https://www.postgresql.org/support/security/"},{"type":"WEB","url":"https://bugzilla.redhat.com/show_bug.cgi?id=1894423"},{"type":"WEB","url":"https://lists.debian.org/debian-lts-announce/2020/12/msg00005.html"},{"type":"WEB","url":"https://security.gentoo.org/glsa/202012-07"},{"type":"WEB","url":"https://security.netapp.com/advisory/ntap-20201202-0003/"},{"type":"WEB","url":"https://www.postgresql.org/support/security/"}],"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":"14.1.0+0"}]}],"database_specific":{"source":"https://github.com/JuliaLang/SecurityAdvisories.jl/tree/generated/osv/2026/JLSEC-2026-26.json"}}],"schema_version":"1.7.5"}
