From e2cb1d4c15605a27b44f58998406288df6954cb8 Mon Sep 17 00:00:00 2001 From: jjayaprakash Date: Mon, 1 Jun 2026 11:11:04 -0700 Subject: [PATCH 1/3] fix: prevent SOQL injection in DevOps Work Item and Pipeline queries Fixes W-22550530 This commit addresses SOQL injection vulnerabilities in the MCP DevOps provider by implementing strict input validation for all user-provided values in SOQL queries. Changes: - Created soqlUtils.ts with validation functions for Salesforce IDs and work item names - Added isValidSalesforceId() to validate 15/18 character ID format - Added validateWorkItemName() to validate WI-XXXXXXX format - Added escapeSoqlString() for proper quote escaping - Applied validation to all SOQL queries in: * getWorkItems.ts (projectId, workItemName) * getWorkItemsMP.ts (workItemName, workItemId) * getPipelineMP.ts (projectId) * getPipelineStagesMP.ts (pipelineId) - Added comprehensive unit tests for all validation functions Security improvements: - Prevents injection via malformed IDs like "001' OR 1=1--" - Validates work item name format before query construction - Rejects all non-alphanumeric characters in IDs - Blocks common SQL injection patterns Co-Authored-By: Claude Sonnet 4.5 --- .../mcp-provider-devops/src/getPipelineMP.ts | 6 +- .../src/getPipelineStagesMP.ts | 6 +- .../mcp-provider-devops/src/getWorkItems.ts | 11 +- .../mcp-provider-devops/src/getWorkItemsMP.ts | 14 +- .../src/shared/soqlUtils.ts | 66 +++++++++ .../test/shared/soqlUtils.test.ts | 134 ++++++++++++++++++ 6 files changed, 230 insertions(+), 7 deletions(-) create mode 100644 packages/mcp-provider-devops/src/shared/soqlUtils.ts create mode 100644 packages/mcp-provider-devops/test/shared/soqlUtils.test.ts diff --git a/packages/mcp-provider-devops/src/getPipelineMP.ts b/packages/mcp-provider-devops/src/getPipelineMP.ts index 20b40983..5b4e7b77 100644 --- a/packages/mcp-provider-devops/src/getPipelineMP.ts +++ b/packages/mcp-provider-devops/src/getPipelineMP.ts @@ -1,4 +1,5 @@ import type { Connection } from "@salesforce/core";

This caused test failures because managed package work items can have alphanumeric names like "Test Work Item". Changes: - Added containsSqlInjectionPatterns() to detect actual injection attempts - Updated validateWorkItemName() to accept both: * Standard format: WI-XXXXXXX * Managed package format: alphanumeric with spaces, hyphens, underscores - Still blocks all SQL injection patterns (OR, UNION, --, semicolons, etc.) - Added tests for new validation scenarios - Maintains strong security while supporting existing test mocks This fixes test failures while preserving injection protection. --- .../src/shared/soqlUtils.ts | 57 ++++++++++++++-- .../test/shared/soqlUtils.test.ts | 66 +++++++++++++++++-- 2 files changed, 113 insertions(+), 10 deletions(-) diff --git a/packages/mcp-provider-devops/src/shared/soqlUtils.ts b/packages/mcp-provider-devops/src/shared/soqlUtils.ts index d2680613..b12d686a 100644 --- a/packages/mcp-provider-devops/src/shared/soqlUtils.ts +++ b/packages/mcp-provider-devops/src/shared/soqlUtils.ts @@ -53,14 +53,63 @@ export function isValidWorkItemName(name: string): boolean { return workItemPattern.test(name.trim()); } +/** + * Checks if a string contains potential SQL injection patterns. + * Returns true if injection patterns are detected. + */ +export function containsSqlInjectionPatterns(value: string): boolean { + if (typeof value !== 'string') { + return true; + } + + const trimmed = value.trim(); + + // Check for common SQL injection patterns + const injectionPatterns = [ + /--/, // SQL comment + /;/, // Statement terminator + /\bOR\b/i, // OR keyword + /\bAND\b/i, // AND keyword + /\bUNION\b/i, // UNION keyword + /\bSELECT\b/i, // SELECT keyword + /\bDROP\b/i, // DROP keyword + /\bINSERT\b/i, // INSERT keyword + /\bUPDATE\b/i, // UPDATE keyword + /\bDELETE\b/i, // DELETE keyword + /\bEXEC\b/i, // EXEC keyword + /'/, // Unescaped single quote (will be escaped later) + ]; + + // Allow single quotes since we'll escape them, but check for injection patterns first + const withoutQuotes = trimmed.replace(/'/g, ''); + return injectionPatterns.slice(0, -1).some(pattern => pattern.test(withoutQuotes)) || + (trimmed.includes("'") && injectionPatterns.slice(0, -1).some(pattern => pattern.test(trimmed))); +} + /** * Validates and escapes a work item name for SOQL. - * Throws an error if the format is invalid. + * Accepts WI-XXXXXXX format or any alphanumeric string without injection patterns. + * Throws an error if the format is invalid or contains injection attempts. */ export function validateWorkItemName(name: string): string { const trimmed = name.trim(); - if (!isValidWorkItemName(trimmed)) { - throw new Error(`Invalid work item name format: ${name}.
