Which packages are affected by GHSA-3xgr-h5hq-7299?

GHSA-3xgr-h5hq-7299 affects the following packages: org.opensearch.dataprepper.plugins:geoip-processor (Maven). Ecosystems affected: Maven.

How do I fix GHSA-3xgr-h5hq-7299?

Update org.opensearch.dataprepper.plugins:geoip-processor to 2.12.2 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-3xgr-h5hq-7299 is resolved across your whole dependency graph.

How do I detect GHSA-3xgr-h5hq-7299 in my Maven dependencies?

Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for org.opensearch.dataprepper.plugins:geoip-processor, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.

How do I mitigate GHSA-3xgr-h5hq-7299 if there is no patch (or I can't update yet)?

If you can't upgrade right away: gate or disable the affected feature, validate untrusted input at the boundary, and avoid passing attacker-controlled data into the vulnerable path. O3's runtime protection blocks exploitation in production as an interim safeguard until the upgrade lands.

Is GHSA-3xgr-h5hq-7299 actively exploited in the wild?

No public exploit code has been indexed for GHSA-3xgr-h5hq-7299 yet. This does not mean the vulnerability cannot be exploited — absence of public exploits does not imply safety. Apply the recommended fix and use O3 Security to monitor your exposure.

☕org.opensearch.dataprepper.plugins:geoip-processor

Real-time download stats are indexed for npm and PyPI packages. This vulnerability affects Maven packages — download data is not available via public APIs for these ecosystems.

Description

Impact

The GeoIP processor in Data Prepper was configured to trust all SSL certificates and disable hostname verification when downloading GeoIP databases from HTTP URLs, making downloads vulnerable to man-in-the-middle attacks.

The GeoIP processor included a custom SSL implementation that completely bypassed certificate validation when downloading GeoIP databases from external sources. The initiateSSL() method incorrectly implemented an approach for trusting all certificates. Specifically it:

Accepted all SSL certificates without validation
Disabled server certificate verification
Disabled client certificate verification
Disabled hostname verification

This configuration made database downloads vulnerable to man-in-the-middle attacks, potentially allowing attackers to serve malicious GeoIP databases that could compromise the integrity of geolocation data processing.

Patches

Data Prepper 2.12.2 contains a fix for this issue.

Workarounds

If upgrading is not immediately possible:

Use local GeoIP database files instead of downloading from HTTP URLs
Ensure database downloads occur only over trusted networks
