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

critical Tenable Self-Hosted Container Security Plugin ID 463112

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,
 create_partition_time() reads the writable part_config.time_encoder text value and interpolates it without
 identifier quoting into a dynamically executed SELECT statement. A role with the documented partman_user
 INSERT and UPDATE privileges can store SQL rather than a function name. When pg_partman_bgw later creates
 a child partition for a text- or UUID-keyed set, the worker executes the stored SQL with
 pg_partman_bgw.role privileges, which default to PostgreSQL superuser. The persistent configuration row
 can repeatedly restore elevated access on later maintenance 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-2026-61781)

Solution

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