Restricted-data disclosure via query-cache eviction race
Published May 8, 2023 · Updated Jan 29, 2025
Incorrect authorization in OpenSearch 1.0.0 through 1.3.9 and 2.0.0 through 2.6.0 allows remote authenticated users to read restricted data. During query-cache eviction, the fine-grained access-control implementation applies document, field, or masking rules incorrectly to one of two concurrent queries. Exploitation requires two concurrent requests to reach the same instance at the four-hour cache-eviction boundary, exposing data otherwise hidden by those rules.
