- Fix
6.8.14- Upgrade org.elasticsearch:elasticsearch to this version or later
Description
Elasticsearch versions before 7.10.0 and 6.8.14 have an information disclosure issue when audit logging and the emit_request_body option is enabled. The Elasticsearch audit log could contain sensitive information such as password hashes or authentication tokens. This could allow an Elasticsearch administrator to view these details.
Affected versions
Maven
| Package | Vulnerable | Fixed in |
|---|---|---|
| org.elasticsearch:elasticsearch | < 6.8.14 |
6.8.14 |
| org.elasticsearch:elasticsearch | >= 7.0.0, < 7.10.0 |
7.10.0 |
How to fix
Move to the fixed version or later with your package manager, update the lockfile, and run your tests. If the package only arrives through another dependency, upgrade that dependency first. If none of its releases pulls a fixed version yet, force the version with your package manager's override.
