{"id":"CVE-2023-2455","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.","aliases":["BIT-postgresql-2023-2455"],"modified":"2026-03-23T05:12:52.612340241Z","published":"2023-06-09T19:15:09.313Z","related":["ALSA-2023:3714","ALSA-2023:4327","ALSA-2023:4527","ALSA-2023:4535","ALSA-2023:4539","ALSA-2023:5269","MGASA-2023-0187","SUSE-SU-2023:2198-1","SUSE-SU-2023:2199-1","SUSE-SU-2023:2200-1","SUSE-SU-2023:2201-1","SUSE-SU-2023:2202-1","SUSE-SU-2023:2205-1","SUSE-SU-2023:2206-1","SUSE-SU-2023:2207-1","SUSE-SU-2023:2219-1","openSUSE-SU-2024:12929-1","openSUSE-SU-2024:12930-1","openSUSE-SU-2024:12931-1","openSUSE-SU-2024:12932-1","openSUSE-SU-2024:12933-1","openSUSE-SU-2024:14360-1","openSUSE-SU-2025:15580-1"],"references":[{"type":"ADVISORY","url":"https://access.redhat.com/security/cve/CVE-2023-2455"},{"type":"ADVISORY","url":"https://security.netapp.com/advisory/ntap-20230706-0006/"},{"type":"ADVISORY","url":"https://www.postgresql.org/support/security/CVE-2023-2455/"}],"affected":[{"database_specific":{"unresolved_ranges":[{"events":[{"introduced":"11.0"},{"fixed":"11.20"}]},{"events":[{"introduced":"12.0"},{"fixed":"12.15"}]},{"events":[{"introduced":"13.0"},{"fixed":"13.11"}]},{"events":[{"introduced":"14.0"},{"fixed":"14.8"}]},{"events":[{"introduced":"15.0"},{"fixed":"15.3"}]},{"events":[{"introduced":"0"},{"last_affected":"8.0"}]},{"events":[{"introduced":"0"},{"last_affected":"9.0"}]},{"events":[{"introduced":"0"},{"last_affected":"38"}]}],"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2023-2455.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:L/A:N"}]}
