CVSS 3.1
6.8 mediumCVSS:3.1/AV:N/AC:H/PR:N/UI:R/S:U/C:N/I:H/A:HCVE-2026-126199 pgEdge Postgres MCP Server write confirmation skipped for writes that begin with a reading keyword
Medium (6.8) in pgedge pgedge-postgres-mcp. EPSS 0.2% estimated probability of exploitation activity in the next 30 days.
pgEdge Postgres MCP Server enables SQL queries against PostgreSQL databases through Model Context Protocol compatible clients. Prior to 1.1.0, the bundled CLI and web clients classified query_database statements only by their first keyword before deciding whether to display a write confirmation. SELECT INTO, data-modifying common table expressions beginning with WITH, and EXPLAIN ANALYZE of a write were treated as reads and could execute without confirmation on an allow_writes connection. Read-only connections remain protected by PostgreSQL transaction access mode, and EXPLAIN without ANALYZE and SELECT FOR UPDATE remain classified as reads. This issue is fixed in 1.1.0.
