| Vector | AV:N/AC:L/Au:S/C:C/I:N/A:N |
Name of the Vulnerable Software and Affected Versions:
Elasticsearch versions prior to 8.14.0
Description:
The issue is related to the implementation of the Elasticsearch search system's application programming interface, specifically with the cross-cluster API key. If a cross-cluster API key restricts search for a given index using the
query or the field security parameter, and the same cross-cluster API key also grants replication for the same index, the search restrictions are not enforced during cross-cluster search operations. This may allow an attacker to disclose protected information. The issue only affects the API key-based security model for remote clusters, which was previously a beta feature and is released as GA with 8.14.0.Recommendations:
As a temporary workaround, consider restricting access to the cross-cluster API key until a patch is available.
For versions prior to 8.14.0, update to version 8.14.0 or later to resolve the issue.
Avoid using the
query or field security parameters in the cross-cluster API key until the issue is resolved.
Restrict access to the API key-based security model for remote clusters to minimize the risk of exploitation.Fix
Improper Access Control
Insecure Storage of Sensitive Information
