{"id":"JLSEC-2026-41","details":"Row security policies disregard user ID changes after inlining; PostgreSQL could permit incorrect policies to be applied in certain cases where role-specific policies are used and a given query is planned under one role and then executed under other roles. This scenario can happen under security definer functions or when a common user and query is planned initially and then re-used across multiple SET ROLEs. Applying an incorrect policy may permit a user to complete otherwise-forbidden reads and modifications. This affects only databases that have used CREATE POLICY to define a row security policy.","modified":"2026-04-03T13:31:12.182865Z","published":"2026-04-03T13:27:15.647Z","upstream":["CVE-2023-2455"],"database_specific":{"license":"CC-BY-4.0","sources":[{"imported":"2026-04-03T13:13:10.297Z","published":"2023-06-09T19:15:09.313Z","modified":"2025-01-06T18:15:13.913Z","html_url":"https://nvd.nist.gov/vuln/detail/CVE-2023-2455","id":"CVE-2023-2455","url":"https://services.nvd.nist.gov/rest/json/cves/2.0?cveId=CVE-2023-2455"}]},"references":[{"type":"WEB","url":"https://access.redhat.com/security/cve/CVE-2023-2455"},{"type":"WEB","url":"https://security.netapp.com/advisory/ntap-20230706-0006/"},{"type":"WEB","url":"https://www.postgresql.org/support/security/CVE-2023-2455/"},{"type":"WEB","url":"https://access.redhat.com/security/cve/CVE-2023-2455"},{"type":"WEB","url":"https://security.netapp.com/advisory/ntap-20230706-0006/"},{"type":"WEB","url":"https://www.postgresql.org/support/security/CVE-2023-2455/"}],"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":"16.0.0+0"}]}],"database_specific":{"source":"https://github.com/JuliaLang/SecurityAdvisories.jl/tree/generated/osv/2026/JLSEC-2026-41.json"}}],"schema_version":"1.7.5"}
