Unauthorized access to documents protected by Document-Level Security (DLS), when Signals watches include a search query involving protected documents

CVE-2025-12148 Medium · 6.0 CWE-200 Oct 29, 2025

Unauthorized access to fields protected by Field Masking (FM) for fields of type IP

In Search Guard versions 3.1.1 and earlier, Field Masking (FM) rules are improperly enforced on fields of type IP (IP Address). While the content of these fields is properly redacted in the _source document returned by search operations, the results do return documents (hits) when searching based on a specific IP values. This allows to reconstruct the original contents of the field. Workaround - If you cannot upgrade immediately, you can avoid the problem by using field level security (FLS) protection on fields of the affected types instead of field masking.

CVE-2025-12147 Medium · 6.0 CWE-200 Oct 29, 2025

Unauthorized access to fields protected by Field-Level Security (FLS) when those fields are members of an object

In Search Guard FLX versions 3.1.1 and earlier, Field-Level Security (FLS) rules are improperly enforced on object-valued fields. When an FLS exclusion rule (e.g., ~field) is applied to a field which contains an object as its value, the object is correctly removed from the _source returned by search operations. However, the object members (i.e., child attributes) remain accessible to search queries. This exposure allows adversaries to infer or reconstruct the original contents of the excluded object. Workaround - If you cannot upgrade immediately and FLS exclusion rules are used for object valued attributes (like ~object), add an additional exclusion rule for the members of the object (like ~object.*).
