{"id":"CVE-2026-61822","published":"2026-09-18T20:17:20.363","lastModified":"2026-09-24T21:17:18.580","description":"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.","cvssScore":6.5,"cvssSeverity":"MEDIUM","cvssVector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H","cwes":["CWE-703"],"vendors":[],"products":[],"references":[{"url":"https://github.com/pgpartman/pg_partman/commit/ba9405542acf24dd881845b935cab8b165854361","tags":[]},{"url":"https://github.com/pgpartman/pg_partman/releases/tag/v5.5.0","tags":[]},{"url":"https://github.com/pgpartman/pg_partman/security/advisories/GHSA-9m6c-hw23-c6h2","tags":[]}],"exploitRefs":[{"url":"https://github.com/pgpartman/pg_partman/commit/ba9405542acf24dd881845b935cab8b165854361","tags":[]},{"url":"https://github.com/pgpartman/pg_partman/releases/tag/v5.5.0","tags":[]},{"url":"https://github.com/pgpartman/pg_partman/security/advisories/GHSA-9m6c-hw23-c6h2","tags":[]}],"hasPoc":true,"ai":null}
