What is CVE-2026-30234?

OpenProject, a widely used open-source project management software, contains a vulnerability allowing authenticated users with BCF import permissions to exploit file path manipulation. Users can upload a specially crafted .bcf archive that alters the value in markup.bcf to point to sensitive local files, such as system configurations or user data. This manipulation enables unauthorized access to filesystem content outside the designated ZIP scope, resulting in potential information leakage. The issue has been addressed in version 17.2.0, highlighting the importance of updating to secure versions.
