What is CVE-2025-12149?

In Search Guard FLX versions prior to 3.1.3, a significant security issue arises when Document-Level Security (DLS) rules are not enforced during searches triggered by Signal's watch feature. This oversight allows unauthorized access to all documents within the queried indices, posing a substantial risk to data confidentiality. It is crucial for users of affected versions to upgrade to 3.1.3 or later to ensure complete compliance with DLS protocols and to safeguard sensitive information.
