CVE-2026-125322 | BDVDB-2026-404638 Detail
pgEdgepgedge-postgres-mcp
Description#
pgEdge Postgres MCP Server enables SQL queries against PostgreSQL databases through Model Context Protocol compatible clients. Prior to 1.1.0, the where parameter of the count_rows tool accepted subqueries against tables other than the table named in the tool call. A caller could use predicates and the returned row count as an inference oracle to extract data from any other table that the connected database role could read. The database privilege boundary remained intact, and the flaw did not grant access to tables outside that role's existing SELECT privileges. This issue is fixed in version 1.1.0.
Impact#
Per CVSS v3.1: confidentiality impact high, integrity impact none, availability impact none. Attack vector: network.
