CVE-2026-32820: CWE-22: Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') in datacycle-engine dataCycle-CORE
A path traversal vulnerability exists in dataCycle-CORE, a module of the dataCycle data management system, in versions up to and including 25.07.3. The vulnerability allows an unauthenticated attacker to traverse outside intended directories and render arbitrary markdown (.md) files from the application or engine root. This occurs because the input path segments are only sanitized with a Rails HTML sanitizer, which does not remove directory traversal sequences. The issue is fixed in version 26.06.08.
AI Analysis
Technical Summary
CVE-2026-32820 is a CWE-22 path traversal vulnerability in dataCycle-CORE (up to version 25.07.3). The documentation and static markdown renderer accepts attacker-controlled path segments that are insufficiently sanitized, allowing traversal outside the intended 'docs' or 'static' directories. An unauthenticated attacker can exploit this to render arbitrary .md files from the application or engine root directories. The vulnerability is patched in version 26.06.08.
Potential Impact
An unauthenticated attacker can read arbitrary markdown files outside the intended directories by exploiting the path traversal flaw. This can lead to unauthorized disclosure of sensitive information contained in those files. The vulnerability does not impact integrity or availability, only confidentiality.
Mitigation Recommendations
Upgrade dataCycle-CORE to version 26.06.08 or later, where this path traversal vulnerability is patched. No other official remediation or temporary fixes are documented. Patch status is confirmed by the vendor advisory indicating the fix in 26.06.08.
