CVE-2026-62853
Published:October 30, 2026
Updated:November 04, 2026
ThingLinks is an enterprise IoT platform. Prior to 1.4.0, the "/groovyScriptTest/registerScript" endpoint accepts user-supplied Groovy script content and passes it to an unsandboxed "Groovy compilation and loading" flow. An authenticated attacker can provide code that is compiled and instantiated on the server, resulting in arbitrary server-side code execution. The issue affects the "rule engine"'s Groovy script test/register flow. This issue is fixed in version 1.4.0.
