CVE-2024-33647Network attack vector

Cross-project data disclosure via unchecked Lucene queries

Published May 14, 2024 · Updated Aug 27, 2025

Improper access control in Polarion ALM before V2404.0 allows remote authenticated users to read items from unauthorized projects. The Apache Lucene-based query engine processes item queries without enforcing the requesting account's project access restrictions. A low-privileged application account is required, and exploitation discloses otherwise restricted project information without modifying it.
