Choosing the right RAG framework impacts development speed, performance, and maintainability. This comprehensive comparison helps you decide between LangChain and RAG Pipeline Utils based on your specific needs.
How we transformed a slow, costly RAG system into a high-performance production service by optimizing every layer of the stack. This case study shares specific techniques, measurements, and code that reduced P95 latency from 2000ms to 800ms.
Production RAG systems handle sensitive data and require comprehensive security measures. This post shares hard-earned lessons from securing RAG deployments at scale, covering authentication, input validation, data privacy, and threat mitigation.
Optimizing RAG pipeline performance requires understanding bottlenecks across embedding generation, vector search, and LLM inference. This guide provides proven techniques for achieving production-grade performance at scale.
Custom embedders allow you to tailor vector representations to your specific domain, improving retrieval accuracy and reducing dependency on external APIs. This deep dive explores the architecture, implementation patterns, and optimization techniques for building production-ready custom embedders.
RAG Pipeline Utils v2.2.0 Enterprise Edition delivers production-ready infrastructure with advanced AI capabilities, comprehensive observability, and enterprise-grade security features. This release establishes the platform as a complete solution for mission-critical RAG deployments.

RAG Pipeline Utils v2.2.0 Enterprise Edition provides the foundation for production RAG deployments at scale.
RAG Pipeline Utils v2.3.1 delivers advanced security enhancements and production hardening improvements. This patch release includes critical updates to JWT validation, path traversal defense mechanisms, and race condition mitigation.
Advanced Replay Protection
The release implements sophisticated replay protection that distinguishes between self-signed tokens (reusable for refresh flows) and external tokens (single-use only):
Consistent Validation Behavior
The strictValidation flag now consistently controls issuer and audience validation:
const validator = new JWTValidator({
secret: process.env.JWT_SECRET,
algorithm: "HS256",
issuer: "my-app",
audience: "api-users",
strictValidation: true, // Consistently enforces iss/aud validation
enableJtiTracking: true, // Prevents replay attacks
});
// Self-signed tokens work correctly for refresh flows
const token = validator.sign({ sub: "user-123" });
validator.verify(token); // First verification
validator.verify(token); // Succeeds (refresh flow support)
// External tokens are blocked on replay
const externalToken = getTokenFromThirdParty();
validator.verify(externalToken); // First use succeeds
validator.verify(externalToken); // Throws "Token replay detected"
Multi-Layer Protection with Iterative Decoding
Path sanitization includes iterative URL decoding (up to 5 passes) to detect sophisticated encoding attacks:
const { sanitizePath } = require("@devilsdev/rag-pipeline-utils");
// Safe paths are normalized
sanitizePath("docs/README.md"); // Returns: "docs/README.md"
// Dangerous paths throw errors
sanitizePath("../../../etc/passwd"); // Throws
sanitizePath("%2e%2e%2f%2e%2e%2fpasswd"); // Throws (URL encoded)
sanitizePath("%252e%252e%252fconfig"); // Throws (double-encoded)
Attack Vectors Blocked:
../../../etc/passwd..\\..\\windows\\system32%2e%2e%2f, %2e%2e%5c%252e%252e%252f to %2e%2e%2f to ../Critical Security Errors Always Throw
Path traversal violations always throw errors, even with throwOnInvalid=false:
const sanitizer = new InputSanitizer({ throwOnInvalid: false });
try {
const safePath = sanitizePath(userInput);
// Use safePath
} catch (error) {
if (error.message.includes("path traversal")) {
// Handle attack attempt
logger.warn("Path traversal blocked", { input: userInput });
return res.status(400).json({ error: "Invalid path" });
}
throw error;
}

This release is 100% backward compatible with v2.3.0. The only breaking change affects advanced users relying on the previous inconsistent strictValidation behavior. See the Migration Guide for details.
This release includes security enhancements based on OWASP best practices and industry-standard defense-in-depth principles. Security-focused community contributors provided valuable feedback.
RAG Pipeline Utils v2.3.1 provides essential security enhancements for production deployments. Upgrade to benefit from these critical security improvements.
