Overview

CVE-2026-67185 is a high-severity vulnerability. It was published on July 28, 2026 and has a CVSS 3.1 base score of 7.5 (HIGH).

This vulnerability has a CVSS 3.1 base score of 7.5, rated HIGH. It can be exploited remotely over the network. No authentication or special privileges are required for exploitation.

Technical 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.

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
