Unauthenticated SSRF in Verba RAG via WebSocket Import

Publication date: 2026-07-21

Last updated on: 2026-07-22

Assigner: VulnCheck

Description

Verba RAG application version 2.1.3 contains an unauthenticated server-side request forgery vulnerability that allows unauthenticated attackers to cause the backend to issue arbitrary HTTP GET requests by supplying attacker-controlled URLs through the WebSocket import endpoint. Attackers can connect to the /ws/import_files WebSocket endpoint without authentication, specify arbitrary URLs in the HTMLReader configuration, and cause the server to fetch internal resources such as co-located database endpoints or cloud instance metadata services to retrieve sensitive credentials.

Attack-Flow Graph

Executive Summary

Verba RAG application version 2.1.3 has an unauthenticated server-side request forgery (SSRF) vulnerability. Attackers can exploit this by connecting to the /ws/import_files WebSocket endpoint without authentication and specifying arbitrary URLs in the HTMLReader configuration. This causes the server to issue arbitrary HTTP GET requests to internal or external resources.

Detection Guidance

Check for unauthorized WebSocket connections to the /ws/import_files endpoint. Monitor network traffic for unexpected HTTP GET requests originating from the Verba RAG application server. Inspect logs for suspicious import_file operations with external URLs.

Impact Analysis

This vulnerability allows attackers to access internal resources like co-located databases or cloud metadata services to steal sensitive credentials. It can lead to unauthorized data exposure, potential data breaches, and compromise of backend systems.

Compliance Impact

This vulnerability could lead to unauthorized access to sensitive data, such as credentials or internal resources, which may violate compliance requirements under GDPR (data protection) and HIPAA (healthcare data privacy). Unauthorized data exposure or access could result in regulatory penalties or breaches of confidentiality obligations.

Mitigation Strategies

Upgrade Verba RAG to a patched version if available. Restrict access to the /ws/import_files endpoint via network policies or authentication. Disable unauthenticated WebSocket imports until a fix is applied. Monitor for unusual outbound requests from the server.
