What is CVE-2025-62505?

LobeChat, an open source chat application, contains a vulnerability in its web-crawler package that allows server-side request forgery through the tools.search.crawlPages tRPC endpoint.

As a result, attackers with valid user credentials can access sensitive internal API information or cloud metadata, highlighting the need for immediate remedial action. Users are strongly urged to update to version 1.136.2, which addresses and resolves this security issue.
