TinyWeb 0.0.8 Path Traversal via URL Path Component

Published Jul 28, 2026 · Updated Jul 28, 2026 · Assigned by VulnCheck

Vendor: GeneralSandman Product: TinyWeb

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.
