LobeChat is an open source chat application platform. The web-crawler package in LobeChat version 1.136.1 allows server-side request forgery (SSRF) in the tools.search.crawlPages tRPC endpoint. A client can supply an arbitrary urls array together with impls containing the value naive. The service passes the user URLs to Crawler.crawl and the naive implementation performs a server-side fetch of each supplied URL without validating or restricting internal network addresses (such as localhost, 127.0.0.1, private IP ranges, or cloud instance metadata endpoints). This allows an attacker with a valid user token (or in development mode using a bypass header) to make the server disclose responses from internal HTTP services, potentially exposing internal API data or cloud metadata credentials. Version 1.136.2 fixes the issue. Update to version 1.136.2. No known workarounds exist.

CVE-2025-62505 [LOW] Lobe Chat vulnerable to Server-Side Request Forgery with native web fetch module
Lobe Chat vulnerable to Server-Side Request Forgery with native web fetch module
### Vulnerability Description
---
Vulnerability Overview
- When the client sends an arbitrary URL array and impl: ["naive"] to the tRPC endpoint tools.search.crawlPages, the server issues outbound HTTP requests directly to those URLs. There is no defensive logic that restricts or validates requests to internal networks (127.0.0.1, localhost, private ranges) or metadata endpoints (169.254.169.254).
- Flow: client input (urls, impls) → service invocation in the tRPC router → the service passes the URLs to Crawler.crawl → the Crawler prioritizes the user-specified impls (naive) → the naive implementation performs a server-side fetch(url) as-is (SSRF) → the server collects responses from internal resources.
