CVE-2026-125320
NVDCVSS scored by security-advisories@github.com
Vulnerability Summary
pgEdge Postgres MCP Server enables SQL queries against PostgreSQL databases through Model Context Protocol compatible clients. Prior to 1.1.0, the HTTP transport did not validate the Origin header on incoming requests. A user who visited an attacker-controlled page could be targeted through DNS rebinding, allowing the page to reach a locally running server and read schemas and query results from configured databases. The issue affected deployments with the HTTP transport enabled on a machine that also ran a browser, while the default stdio transport was not reachable through this path. This issue is fixed in version 1.1.0.
