Overview

CVE-2025-2506 is a medium-severity vulnerability. It was published on May 22, 2025 and has a CVSS 3.1 base score of 5.3 (MEDIUM).

This vulnerability has a CVSS 3.1 base score of 5.3, rated MEDIUM. It can be exploited remotely over the network. Some level of privileges is required for exploitation.

Technical description

When pglogical attempts to replicate data, it does not verify it is using a replication connection, which means a user with CONNECT access to a database configured for replication can execute the pglogical command to obtain read access to replicated tables. When pglogical runs it should verify it is running on a replication connection but does not perform this check. This vulnerability was introduced in the pglogical 3.x codebase, which is proprietary to EDB. The same code base has been integrated into BDR/PGD 4 and 5.

To exploit the vulnerability the attacker needs at least CONNECT permissions to a database configured for replication and must understand a number of pglogical3/BDR specific commands and be able to decode the binary protocol.

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
