Upgrade to a fixed release named by the vendor:

- To mitigate this vulnerability, ensure that the REPLICATION privilege is granted only to highly trusted database superusers. Regularly review user privileges to confirm that non-superuser accounts do not possess the REPLICATION privilege unless absolutely necessary and their activities are closely monitored. If logical decoding is not actively used, consider disabling it to further reduce the attack surface, though specific configuration steps for disabling logical decoding are beyond the scope of this mitigation.

1 advisory- Advisory severityHigh7.2
High [CVE-2026-6471] Arbitrary code execution via logical decoding plugin
CVE-2026-6471Source published Source updated
Missing authorization in PostgreSQL logical decoding allows a non-superuser holding REPLICATION privilege to dlopen any file visible to the operating system account running the server, via the choice of logical decoding plugin. This in turn runs arbitrary code as that account. Versions before PostgreSQL 18.5, 17.11, 16.15, 15.19, and 14.24 are affected. A flaw was found in PostgreSQL. Exploitation requires an attacker to already have significant access to the database, specifically the REPLICATION role, which is not granted by default to typical users, thus reducing the overall risk. Red Hat severity: Important — CVSS 7.2 (CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:H). Weakness: CWE-94.
