Echo: pg-partman: security update to 5.5.0-1

high Tenable Cloud Security Plugin ID 462750

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - pg_partman is a PostgreSQL extension that manages partitioned tables by time or ID. Prior to 5.5.0,
 drop_partition_id() and drop_partition_time() use part_config.retention_schema as the target for ALTER
 TABLE SET SCHEMA and accept any nonempty schema name. A role with partman_user access can select a target
 schema where the role lacks the normal CREATE privilege, and the background worker performs the relocation
 with pg_partman_bgw.role privileges, which default to PostgreSQL superuser, bypassing the authorization
 check that a normal ALTER TABLE SET SCHEMA operation would enforce. This permits unauthorized relocation
 of retained child tables between schemas. This issue is fixed in version 5.5.0. (CVE-2026-61821)

Solution

Update the pg-partman library and its related packages to version 5.5.0-1 or later.
