CVE-2026-62853 Details
Description
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.
A remote code execution vulnerability has been identified in ThingLinks versions prior to 1.4.0. The issue arises in the rule engine's Groovy script registration test endpoint, '/groovyScriptTest/registerScript', which accepts user-provided Groovy scripts and executes them in an unsandboxed environment. This allows authenticated attackers to execute arbitrary code on the server.
Users can upgrade to ThingLinks version 1.4.0 or later to address this vulnerability.
