Description
CVE-2026-126197 is a high-severity SQL injection vulnerability in pgEdge pgedge-postgres-mcp versions prior to 1.1.0. It affects custom pl-do tools that interpolate JSON arguments into PostgreSQL DO blocks using fixed dollar-quote tags. Malicious input containing specific tags can terminate the block and inject arbitrary SQL or procedural code, bypassing read-only restrictions and allowing unauthorized data access or modification. The vulnerability is fixed in version 1.1.0.
