Technical description

Information disclosure in the file URI processing of File (Field) Paths in Drupal File (Field) Paths 7.x prior to 7.1.3 on Drupal 7.x allows authenticated users to disclose other users’ private files via filename‑collision uploads. This can cause hook_node_insert() consumers (for example, email attachment modules) to receive the wrong file URI, bypassing normal access controls on private files.

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
