CVE-2026-24469 (GCVE-0-2026-24469)

Vulnerability from cvelistv5 – Published: 2026-01-24 01:50 – Updated: 2026-01-26 16:17

Title

C++ HTTP Server has Critical Path Traversal Vulnerability in RequestHandler Allowing Arbitrary File Read

Summary

C++ HTTP Server is an HTTP/1.1 server built to handle client connections and serve HTTP requests. Versions 1.0 and below are vulnerable to Path Traversal via the RequestHandler::handleRequest method. This flaw allows an unauthenticated, remote attacker to read arbitrary files from the server's filesystem by crafting a malicious HTTP GET request containing ../ sequences. The application fails to sanitize the filename variable derived from the user-controlled URL path, directly concatenating it to the files_directory base path and enabling traversal outside the intended root. No patch was available at the time of publication.

Severity

7.5 (High)
