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

high Tenable Cloud Security Plugin ID 457636

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, when
pg_jobmon is installed and part_config.jobmon is true, exception handlers in multiple pg_partman functions
place p_parent_table verbatim inside a SQL string literal used to call pg_jobmon.add_job(). A partman_user
can create a parent-table name containing a single quote that terminates the literal and injects SQL when
an affected exception path runs. If pg_partman_bgw reaches that path, the injected SQL 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 persistent part_config row
can trigger the escalation again on later maintenance ticks. This issue is fixed in version 5.5.0.
(CVE-2026-61819)

Solution

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