CVE-2022-41918: Amazon Opensearch

Medium severity, CVSS 6.3. EPSS: 0.5% chance of exploitation in the next 30 days.

OpenSearch is a community-driven, open source fork of Elasticsearch and Kibana. There is an issue with the implementation of fine-grained access control rules (document-level security, field-level security and field masking) where they are not correctly applied to the indices that back data streams potentially leading to incorrect access authorization. OpenSearch 1.3.7 and 2.4.0 contain a fix for this issue. Users are advised to update. There are no known workarounds for this issue.

Affected products

• Amazon Opensearch: before 1.3.7 (fixed in 1.3.7); from 2.0.0, before 2.4.0 (fixed in 2.4.0)
