Path Traversal in dataCycle-CORE

Publication date: 2026-07-20

Last updated on: 2026-07-20

Assigner: GitHub, Inc.

Description
dataCycle is a data management system for centrally storing, managing, searching, finding, and distributing data. In dataCycle-CORE, the module handling core processing and framework rules, before and including version 25.07.3, the documentation and static markdown renderer accepts attacker-controlled path segments and only runs them through the Rails HTML sanitizer, which does not remove directory traversal sequences. An unauthenticated attacker can traverse out of the intended `docs` or `static` directories and render arbitrary `.md` files from the application root or engine root. This is patched in version 26.06.08.

Executive Summary

This is a path traversal vulnerability in dataCycle-CORE, a data management system. The flaw exists in the documentation and static markdown renderer, which fails to properly sanitize attacker-controlled path segments. The Rails HTML sanitizer used does not remove directory traversal sequences, allowing unauthenticated attackers to escape intended directories and access arbitrary .md files from the application root or engine root.

Detection Guidance

Check if your dataCycle-CORE version is 25.07.3 or earlier. Inspect web server logs for unusual requests targeting documentation or static markdown paths with directory traversal sequences like ../. Test by attempting to access arbitrary .md files outside the intended directories.

Impact Analysis

An unauthenticated attacker could read sensitive files outside the intended directories, potentially exposing confidential data stored in .md files. This could include configuration details, internal documentation, or other sensitive information.

Compliance Impact

This vulnerability could lead to unauthorized access to sensitive data, violating compliance requirements such as GDPR (data protection) or HIPAA (health information privacy). Unauthorized file access may result in data breaches, triggering legal and regulatory penalties.

Mitigation Strategies

Upgrade dataCycle-CORE to version 26.06.08 or later immediately. If upgrading is not possible, restrict access to the vulnerable endpoints via firewall rules or web server configuration until patched.
