CyberRota Analysis
AI-GeneratedThe Logto Tunnel npm package prior to version 0.3.9 is vulnerable to path traversal attacks, allowing unauthenticated users to access files outside the designated static directory by manipulating the request URL. This could lead to unauthorized file disclosure, potentially exposing sensitive information. Organizations using Logto Tunnel should prioritize upgrading to version 0.3.9 to mitigate this high-severity vulnerability.

Original NVD Description
Logto is the modern, open-source auth infrastructure for SaaS and AI apps. Prior to 0.3.9, the Logto Tunnel npm package enabled createStaticFileProxy from packages/tunnel/src/commands/tunnel/index.ts and passed request.url from static asset requests through packages/tunnel/src/commands/tunnel/utils.ts using path.join(staticPath, request.url) and then fs.open(requestPath, "r") without URL normalization or a containment check. When --experience-path was enabled and the tunnel port was reachable, an unauthenticated requester could send a path containing ../ to createStaticFileProxy and read files outside the configured static directory that were readable by the logto-tunnel process. The service used server.listen(port), which could expose the tunnel to other hosts depending on the platform and deployment. This issue is fixed in version 0.3.9.
