{"id":"JLSEC-2026-48","details":"Client use of server error message in PostgreSQL allows a server not trusted under current SSL or GSS settings to furnish arbitrary non-NUL bytes to the libpq application.  For example, a man-in-the-middle attacker could send a long error message that a human or screen-scraper user of psql mistakes for valid query results.  This is probably not a concern for clients where the user interface unambiguously indicates the boundary between one error message and other text.  Versions before PostgreSQL 17.1, 16.5, 15.9, 14.14, 13.17, and 12.21 are affected.","modified":"2026-07-18T00:02:07.179626191Z","published":"2026-04-03T13:27:15.647Z","upstream":["CVE-2024-10977"],"database_specific":{"license":"CC-BY-4.0","sources":[{"url":"https://services.nvd.nist.gov/rest/json/cves/2.0?cveId=CVE-2024-10977","html_url":"https://nvd.nist.gov/vuln/detail/CVE-2024-10977","database_specific":{"status":"Modified"},"id":"CVE-2024-10977","imported":"2026-07-17T21:58:46.765Z","modified":"2026-06-17T06:56:49.087Z","published":"2024-11-14T13:15:04.023Z"}]},"references":[{"type":"WEB","url":"https://lists.debian.org/debian-lts-announce/2024/11/msg00011.html"},{"type":"WEB","url":"https://www.postgresql.org/support/security/CVE-2024-10977/"}],"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-2026-48.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:L/A:N"}]}
