What is CVE-2026-67185?

The TinyWeb server, through version 0.0.8, is susceptible to a path traversal vulnerability that enables unauthorized attackers to access arbitrary files on the server. By exploiting the vulnerability, attackers can manipulate the URL path using '../' sequences, which are directly concatenated to the configured web root without proper checks. This allows unauthorized access to sensitive files such as credential stores and private keys, especially when the server operates under elevated privileges. The issue arises from the failure to normalize the URL input and the lack of boundary checks in the request handling process.
