CVE-2022-24816Known exploitationPublic exploitNetwork attack vector

Unauthenticated code execution via unescaped Jiffle comments

Published Apr 13, 2022 · Updated Oct 21, 2025

Code injection in GeoSolutions JAI-EXT before 1.1.22 allows remote attackers to execute arbitrary code through Jiffle scripts. Script.write embeds attacker-controlled Jiffle text in a Java documentation comment without escaping comment terminators, and Janino compiles the resulting injected Java source. Exposure requires a consuming application, such as GeoServer, to accept Jiffle scripts over the network; default GeoServer deployments expose this path without authentication.
