Detailsinfo

A vulnerability has been found in Camunda up to 7.23.16/7.24.13 and classified as critical. Affected by this vulnerability is the function AdhocQueryValidator.validate of the component AdhocQueryValidator. The manipulation of the argument orQueries with an unknown input leads to a code injection vulnerability. The CWE definition for the vulnerability is CWE-94. The product constructs all or part of a code segment using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the syntax or behavior of the intended code segment. As an impact it is known to affect confidentiality, integrity, and availability. The summary by CVE is:

Camunda 7.24.0 before 7.24.14 and 7.23.0 before 7.23.17 contains an expression injection vulnerability where AdhocQueryValidator.validate() fails to check sub-query expression maps within the orQueries field exposed by TaskQueryDto, allowing authenticated users to bypass the enableExpressionsInAdhocQueries restriction. Attackers can supply a malicious JUEL expression such as dueAfterExpression inside an orQueries entry to achieve arbitrary Java reflection and invoke java.lang.Runtime.exec, resulting in operating-system command execution as the engine service user.

The advisory is shared at codeant.ai. This vulnerability is known as CVE-2026-109432 since 10/12/2026. The exploitation appears to be easy. The attack can be launched remotely.
