CVE-2026-90488 Details
Description
A vulnerability was determined in Xuxueli xxl-job up to 3.4.2. This affects the function GroovyClassLoader.parseClass of the file xxl-job-core/src/main/java/com/xxl/job/core/glue/GlueFactory.java. This manipulation causes code injection. Remote exploitation of the attack is possible. The exploit has been publicly disclosed and may be utilized. The vendor was contacted early about this disclosure but did not respond in any way.
A remote code execution vulnerability exists in Xuxueli XXL-Job versions through 3.4.2. The issue arises in the GlueFactory component, specifically within the GroovyClassLoader.parseClass method, which processes user-supplied Groovy code without any sandbox restrictions. This flaw allows authenticated users with jobGroup permissions to execute arbitrary code on the executor server with full system privileges. The vulnerability has been publicly disclosed and exploited.
To address this vulnerability, implement a Groovy sandbox by using the SecureASTCustomizer and CompilerConfiguration classes to block dangerous imports and method calls before compiling user-provided Groovy code.
