Exploitation Summary
EIP tracks 1 public exploit for CVE-2026-67185. PoCs published by theopaid.
AI-analyzed exploit summary Detailed technical analysis of CVE-2026-67185, an unauthenticated path traversal vulnerability in TinyWeb (versions up to commit a381da2). The flaw allows arbitrary file read via crafted `../` sequences in the request URL due to lack of path normalization or dot-segment removal. The writeup includes root cause analysis, vulnerable code snippets, and a functional PoC using curl.
Description
TinyWeb through 0.0.8 contains a path traversal vulnerability that allows unauthenticated attackers to read arbitrary files by submitting ../ sequences in the URL path, which are concatenated directly to the configured web root in HttpBuilder::buildResponse() without normalization, dot-segment removal, or boundary checks. Attackers can craft a single request with ../ sequences that pass through the URL parser unchanged and reach the filesystem call via HttpFile::setFile(), exposing sensitive files such as credential stores and private keys when the server process runs as root.
