{"id":"CVE-2026-61822","summary":"pg_partman disable maintenance for all partition sets","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.","aliases":["GHSA-9m6c-hw23-c6h2"],"modified":"2026-09-20T11:46:54.605441421Z","published":"2026-09-18T19:45:49.852Z","database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/61xxx/CVE-2026-61822.json","cna_assigner":"GitHub_M","cwe_ids":["CWE-703"]},"references":[{"type":"WEB","url":"https://github.com/pgpartman/pg_partman/releases/tag/v5.5.0"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/61xxx/CVE-2026-61822.json"},{"type":"ADVISORY","url":"https://github.com/pgpartman/pg_partman/security/advisories/GHSA-9m6c-hw23-c6h2"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-61822"},{"type":"FIX","url":"https://github.com/pgpartman/pg_partman/commit/ba9405542acf24dd881845b935cab8b165854361"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/pgpartman/pg_partman","events":[{"introduced":"0"},{"fixed":"ba9405542acf24dd881845b935cab8b165854361"},{"fixed":"f7e83b9c441c7e97066d815bbe14e02a9dc5ff94"}],"database_specific":{"extracted_events":[{"introduced":"0"},{"fixed":"5.5.0"}],"source":["AFFECTED_FIELD","REFERENCES"]}}],"versions":["v5.4.3","v5.4.2","v5.4.1","v5.4.0","v5.3.1","v5.3.0","v5.3.0RC1","v5.2.4","v5.2.3","v5.2.2","v5.2.1","v5.2.0","v5.1.0","v5.0.1","v5.0.0","v4.7.1","v4.7.0","v4.6.2","v4.6.1","v4.6.0","v4.5.1","v4.5.0","v4.4.1","v4.4.0","v4.3.1","v4.3.0","v4.2.2","v4.2.1","v4.2.0","v4.1.0","v4.0.0","v3.2.1","v3.2.0","v3.1.3","v3.1.2","v3.1.1","v3.1.0","v3.0.2","v3.0.1","v2.6.4","v2.6.3","v2.6.2","v2.6.1","v2.6.0","v2.5.1","v2.5.0","v2.4.1","v2.4.0","v2.3.4","v2.3.3","v2.3.2","v2.3.1","v2.3.0","v2.2.3","v2.2.2","v2.2.1","v2.2.0","v2.1.0","v2.0.0","v1.8.7","v1.8.6","v1.8.5","v1.8.4","v1.8.3","v1.8.2","v1.8.1","v1.8.0","v1.7.2","v1.7.1","v1.7.0","v1.6.1","v1.6.0","v1.5.1","v1.5.0","v1.4.5","v1.4.4","v1.4.3","v1.4.1","v1.4.0","v1.3.0","v1.2.0","v1.1.0","v1.0.0","v0.4.2","v0.4.1","v0.4.0","v0.3.2","v0.3.1","v0.3.0","v0.2.0","v0.1.2","v0.1.1"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/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"}]}
