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

high Tenable Cloud Security Plugin ID 463872

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,
 run_maintenance(), show_partitions(), show_partition_info(), undo_partition(), and partition_data_time()
 interpolate the writable part_config.time_dncoder text value without identifier quoting into dynamic SQL.
 A role with the documented partman_user privileges can store SQL rather than a decoder function name. When
 an affected operation later uses the poisoned value, including pg_partman_bgw maintenance for a text- or
 UUID-keyed set, the SQL executes with the operation's privileges, which can be the default PostgreSQL
 superuser background-worker role. The persistent row can restore elevated access on later ticks, and
 successful exploitation can permit database-wide compromise and operating-system command execution as the
 PostgreSQL service account. This issue is fixed in version 5.5.0. (CVE-2026-61817)

Solution

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