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

high Tenable Cloud Security Plugin ID 461508

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,
undo_partition() reads part_config.time_encoder as unrestricted text and interpolates it without
identifier quoting into a dynamically executed SELECT statement. A role with partman_user access can store
SQL rather than a function name, and the SQL executes with the privileges of the caller that invokes
undo_partition(). The function is not part of the default background-worker path, which limits the
automatic superuser escalation described by the related create-partition vulnerability, but a privileged
caller can still have its available confidentiality, integrity, and availability permissions abused. This
issue is fixed in version 5.5.0. (CVE-2026-61818)

Solution

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