CVE-2022-24816 OSGeo GeoServer JAI-EXT Code Injection Vulnerability
OSGeo GeoServer JAI-EXT contains a code injection vulnerability that, when programs use jt-jiffle and allow Jiffle script to be provided via network request, could allow remote code execution.
From the CISA KEV catalogue version 2026.11.06, with Cybergen analysis. Updated 6 Nov 2026.
Should You Worry?
- CISA confirmed exploitation in the wild and added it to the Known Exploited Vulnerabilities catalogue on 26 Jun 2024.
- Rated Critical severity (CVSS 10.0, scored by Vendor).
- It has been in the catalogue for 863 days. Systems still unpatched now have almost certainly been scanned for it.
What It Is
JAI-EXT is an open-source project which aims to extend the Java Advanced Imaging (JAI) API. Programs allowing Jiffle script to be provided via network request can lead to a Remote Code Execution as the Jiffle script is compiled into Java code via Janino, and executed. In particular, this affects the downstream GeoServer project. Version 1.2.22 will contain a patch that disables the ability to inject malicious code into the resulting script. Users unable to upgrade may negate the ability to compile Jiffle scripts from the final application, by removing janino-x.y.z.jar from the classpath.

What To Do Now
- 1
Find it
Search your asset inventory and external attack surface for OSGeo JAI-EXT. Include cloud images, appliances and anything a supplier runs for you.
Attack Surface Management - 2
Fix it
Apply mitigations per vendor instructions or discontinue use of the product if mitigations are unavailable.
Vulnerability Management - 3
Hunt for compromise
If an affected system was reachable before you patched, assume it may have been hit. Check logs, new accounts, web shells and outbound connections from the date of exposure.
Incident Response - 4
Prove it is fixed
Rescan or test the system after patching. Upgrades that fail silently and forgotten secondary instances are common.
