What is CVE-2025-62487?

A vulnerability has been identified in the Palantir Dossier front-end application where images uploaded were not properly marked with security levels. This oversight stemmed from a change made in May 2025 to facilitate file sharing across artifacts. In installations without Context-Based Access Control (CBAC), users were not presented with the necessary dialog to select appropriate security levels, leading to potential unauthorized access to sensitive materials. Consequently, files were only protected by the default authorization rules, which generally included broad access permissions.
