Path Traversal Vulnerability in Known Through 0.33.0

Publication date: 2026-09-10

Last updated on: 2026-09-10

Assigner: VulnCheck

Description
knowns through 0.33.0 fails to validate the path query parameter in the workspace browse endpoint, allowing remote attackers to enumerate arbitrary directories on the host filesystem. Attackers can traverse the directory structure to locate project directories and identify targets for further exploitation.

Executive Summary

CVE-2026-88940 is a path traversal vulnerability in the knowns software versions up to 0.33.0. It occurs because the path query parameter in the workspace browse endpoint is not properly validated. This allows remote attackers to traverse directories and enumerate arbitrary folders on the host filesystem, potentially identifying project directories for further attacks.

Detection Guidance

To detect this vulnerability, check if your knowns software version is 0.33.0 or lower. Test the /api/workspaces/browse endpoint by sending a GET request with a path traversal payload like ../ to see if it returns directory listings outside intended paths.

Impact Analysis

Attackers can exploit this to enumerate directories on your system, locate sensitive project files, and gain unauthorized access to repositories. This could lead to data theft, code manipulation, or further compromise of your system's confidentiality, integrity, and availability.

Compliance Impact

This vulnerability could lead to unauthorized access to sensitive data, violating GDPR's data protection principles and HIPAA's security requirements. It may result in data breaches, non-compliance penalties, and loss of trust due to compromised confidentiality and integrity of personal or health information.

Mitigation Strategies

Immediately upgrade knowns to a version higher than 0.33.0. If upgrading is not possible, restrict access to the /api/workspaces/browse endpoint and implement strict input validation for path parameters to prevent directory traversal.
