What happened

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.

About this data

This record was ingested from a data source. Retrieved: Oct 26, 2026, 19:40 UTC. Ingestion is not an independent editorial investigation.

NVD status: Deferred. Publication in the NVD is not evidence of exploitation.

A CISA KEV listing documents known exploitation, not necessarily a zero-day; absence from the catalog does not prove a vulnerability has never been exploited.

Technology tags indicate possible relevance, not verified exposure. Confirm the affected product, version, and configuration against your own inventory; KEVWire does not scan your systems.

A personal reading checklist on this device, not verified remediation.
