CVE-2026-109432: Camunda Expression Injection via orQueries RCE

• Severity: critical (CVSS 9.8 v3.1)
• Exploited in the wild: not listed in CISA KEV
• EPSS: 0.6% probability of exploitation in the next 30 days
• Public exploit or detection template: none known
• Published: 2026-10-19 · updated 2026-10-19
• Weakness: CWE-78

Description

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.

Affected products

• Camunda 7: from 7.24.0 before 7.24.14; from 7.23.0 before 7.23.17 — fixed in 7.23.17, 7.24.14

How to fix

Upgrade to a fixed version: Camunda 7 7.23.17, 7.24.14. Check the vendor advisory for mitigations.
