Prior to 5.5.0, when pg_jobmon is installed and part_config.jobmon is true, exception handlers in multiple pg_partman functions place p_parent_table verbatim inside a SQL string literal used to call pg_jobmon.add_job(). A partman_user can create a parent-table name containing a single quote that terminates the literal and injects SQL when an affected exception path runs. If pg_partman_bgw reaches that path, the injected SQL executes with pg_partman_bgw.role privileges, which default to PostgreSQL superuser, permitting database-wide compromise and operating-system command execution as the PostgreSQL service account. The persistent part_config row can trigger the escalation again on later maintenance ticks. This issue is fixed in version 5.5.0.","published":"2026-09-18T20:17:19.927","modified":"2026-09-18T20:17:19.927","cvss":{"score":8.5,"severity":"HIGH","vector":"CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:C/C:H/I:H/A:H"},"epss":null,"cisaKev":null,"exploitsKnown":null,"affectedPackages":[],"fix":{"url":"https://github.com/pgpartman/pg_partman/commit/ba9405542acf24dd881845b935cab8b165854361","label":"pgpartman/pg_partman@ba94055"},"references":[{"type":"WEB","url":"https://github.com/pgpartman/pg_partman/commit/ba9405542acf24dd881845b935cab8b165854361"},{"type":"WEB","url":"https://github.com/pgpartman/pg_partman/releases/tag/v5.5.0"},{"type":"WEB","url":"https://github.com/pgpartman/pg_partman/security/advisories/GHSA-gv5h-j2cm-rhc3"}],"provenance":{"sources":["OSV.dev","NVD","FIRST.org (EPSS)"],"lastVerified":"2026-09-18T20:17:19.927"}}
