Description

This security bulletin contains information about 1 vulnerability.


1) Untrusted search path (CVE-ID: CVE-2026-100402)

CWE-ID: CWE-426 - Untrusted Search Path

CVSSv4: 8.6 [CVSS:4.0/AV:N/AC:L/AT:N/PR:H/UI:N/VC:H/VI:H/VA:L/SC:N/SI:N/SA:N]


The vulnerability allows a highly privileged remote attacker with permission to create temporary objects to gain PostgreSQL superuser privileges.

The vulnerability exists due to SECURITY DEFINER functions in aiven-extras omitting pg_temp from search_path, allowing temporary types to shadow unqualified casts. A highly privileged remote attacker can create a temporary domain and invoke an affected function, causing its malicious constraint to execute as the postgres superuser.
