{"id":"DEBIAN-CVE-2026-61822","details":"pg_partman is a PostgreSQL extension that manages partitioned tables by time or ID. Prior to 5.5.0, run_maintenance() handles exceptions outside the loop that processes rows from part_config, so an exception for one partition set immediately terminates the loop and skips every later set. A role with partman_user access can insert or update a row that reliably fails and assign it a low maintenance_order value so it is processed before legitimate rows. Repeated maintenance ticks then abort before legitimate partition sets are maintained, causing database-wide loss of automated partition maintenance. This issue is fixed in version 5.5.0.","modified":"2026-09-25T08:47:24.390001544Z","published":"2026-09-18T20:17:20.363Z","upstream":["CVE-2026-61822"],"references":[{"type":"ADVISORY","url":"https://security-tracker.debian.org/tracker/CVE-2026-61822"}],"affected":[{"package":{"name":"pg-partman","ecosystem":"Debian:12","purl":"pkg:deb/debian/pg-partman?arch=source&distro=bookworm"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["4.7.2-1","4.7.3-1","4.7.4-2","5.0.0-1","5.0.0-2","5.0.1-1","5.1.0-1","5.1.0-2","5.2.0-1","5.2.1-1","5.2.2-1","5.2.4-1","5.3.0-1","5.3.0~rc1-1","5.3.1-1","5.3.1-2","5.4.0-1","5.4.1-1","5.4.2-1","5.4.3-1","5.5.0-1"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-61822.json"}},{"package":{"name":"pg-partman","ecosystem":"Debian:13","purl":"pkg:deb/debian/pg-partman?arch=source&distro=trixie"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["5.2.4-1","5.3.0-1","5.3.0~rc1-1","5.3.1-1","5.3.1-2","5.4.0-1","5.4.1-1","5.4.2-1","5.4.3-1","5.5.0-1"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-61822.json"}},{"package":{"name":"pg-partman","ecosystem":"Debian:14","purl":"pkg:deb/debian/pg-partman?arch=source&distro=forky"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"5.5.0-1"}]}],"versions":["5.2.4-1","5.3.0-1","5.3.0~rc1-1","5.3.1-1","5.3.1-2","5.4.0-1","5.4.1-1","5.4.2-1","5.4.3-1"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-61822.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H"}]}
