Prior to 5.5.0, inherit_template_properties() manually surrounds primary-key column names from pg_attribute.attname with double quotes without escaping embedded double-quote characters. A partman_user who owns a template table can create a crafted column name that breaks out of the generated ALTER TABLE ADD PRIMARY KEY identifier when the background worker applies the key to a child partition. The generated SQL then 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 crafted catalog identifier persists until removed and can trigger again during later partition creation. This issue is fixed in version 5.5.0."}],"source":{"advisory":"GHSA-xqxh-6hh3-974m","discovery":"UNKNOWN"}},"adp":[{"metrics":[{"other":{"type":"ssvc","content":{"timestamp":"2026-09-22T15:39:28.982624Z","id":"CVE-2026-61820","options":[{"Exploitation":"none"},{"Automatable":"no"},{"Technical Impact":"total"}],"role":"CISA Coordinator","version":"2.0.3"}}}],"title":"CISA ADP Vulnrichment","providerMetadata":{"orgId":"134c704f-9b21-4f2e-91b3-4a467353bcc0","shortName":"CISA-ADP","dateUpdated":"2026-09-22T15:39:45.442Z"}}]}}
