There is an issue in the implementation of field-level security (FLS) and field masking where rules written to explicitly exclude fields are not correctly applied for certain queries that rely on their auto-generated .keyword fields.
This issue is only present for authenticated users with read access to the indexes containing the restricted fields.
FLS rules that use explicit exclusions can be written to grant explicit access instead. Policies authored in this way are not subject to this issue.
OpenSearch versions 1.3.8 and 2.5.0 contain a fix for this issue.
If you have any questions or comments about this advisory, please contact AWS/Amazon Security via our issue reporting page (https://aws.amazon.com/security/vulnerability-reporting/) or directly via email to [email protected]. Please do not create a public GitHub issue.
