CVE-2026-67185

TinyWeb 0.0.8 Path Traversal via URL Path Component

Published Jul 28, 2026 CVSS 4.0 · 8.7 High EPSS < 1% KEV · Not listed
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.
