| CVE-2026-126196 | 1 Pgedge | 1 Pgedge-postgres-mcp | 2026-11-13 | 8.1 High |
| pgEdge Postgres MCP Server enables SQL queries against PostgreSQL databases through Model Context Protocol compatible clients. Prior to 1.1.0, query_database on a read_only connection could send unrecognized statements through pgx Exec without bind parameters, selecting PostgreSQL's simple query protocol and allowing multiple semicolon-separated statements in one request. A caller could combine transaction or session state changes with database writes, and pooled session state could leave later calls writable, when the connecting role held write privileges. The flaw affected deployments relying on read_only as a safety boundary, could compromise integrity and availability, and did not add confidentiality impact beyond the reads already permitted by the connection. This issue is fixed in 1.1.0. | ||||
| CVE-2026-126197 | 1 Pgedge | 1 Pgedge-postgres-mcp | 2026-11-13 | 8.8 High |
| pgEdge Postgres MCP Server enables SQL queries against PostgreSQL databases through Model Context Protocol compatible clients. Prior to 1.1.0, custom pl-do tools interpolated JSON arguments into a PostgreSQL DO block delimited by fixed dollar-quote tags. An argument containing $mcp_custom_tool$ could terminate the block and inject arbitrary SQL statements, while $mcp_args$ could inject procedural code into a plpgsql block. Because the statement used the simple query protocol, injected text could include additional statements and transaction control, bypassing read_only and accessing data or modifying resources available to the connecting role. The issue requires at least one pl-do custom tool; sql and pl-func tools pass arguments as bind parameters and are not affected by this injection mechanism. This issue is fixed in 1.1.0. | ||||
| CVE-2026-126198 | 1 Pgedge | 1 Pgedge-postgres-mcp | 2026-11-13 | 3.1 Low |
| pgEdge Postgres MCP Server enables SQL queries against PostgreSQL databases through Model Context Protocol compatible clients. Prior to 1.1.0, the bundled clients, including the CLI and web client, decided whether to request write confirmation by checking only for the query_database tool name instead of server-published write annotations. Custom pl-do, pl-func, and writing sql tools therefore ran without confirmation on allow_writes connections, including when a model followed instructions in retrieved content. The affected control is a bundled-client warning rather than a server authorization boundary, and other MCP clients do not inherit that prompt. This issue is fixed in 1.1.0. | ||||
| CVE-2026-126199 | 1 Pgedge | 1 Pgedge-postgres-mcp | 2026-11-13 | 6.8 Medium |
| 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. | ||||
