Machine-written summary
Summary written by Claude Haiku from the source advisory. Not reviewed by a person.
The geoip-processor Maven package (org.opensearch.dataprepper.plugins), versions 2.7.0 up to but not including 2.12.2, disables SSL certificate and hostname validation when downloading GeoIP databases over HTTPS. An attacker positioned on the network path between the processor and the download source could intercept the connection and serve a malicious database, affecting the integrity of geolocation data. Upgrade to version 2.12.2. Until then, use local database files rather than downloading them.
