CVE-2026-42555 Details
Description
Valtimo is an open-source business process automation platform. com.ritense.valtimo:document from 12.0.0 to before 12.32.0, com.ritense.valtimo:case from 13.0.0 to before 13.23.0, and com.ritense.valtimo:contract from 13.4.0 to before 13.23.0 evaluate Spring Expression Language (SpEL) expressions from user-supplied input using StandardEvaluationContext, which provides unrestricted access to Java types and methods. An authenticated user with the ADMIN role can achieve Remote Code Execution and credential exfiltration. This vulnerability is fixed in com.ritense.valtimo:document 2.32.0, com.ritense.valtimo:case 13.23.0, and com.ritense.valtimo:contract 13.23.0.
A remote code execution vulnerability has been identified in Valtimo, an open-source business process automation platform. This issue affects the 'document', 'case', and 'contract' components across several versions. The vulnerability arises because these components evaluate user-supplied Spring Expression Language (SpEL) expressions using StandardEvaluationContext, which allows unrestricted access to Java types and methods. An authenticated user with the ADMIN role can exploit this to execute arbitrary OS commands and exfiltrate sensitive credentials.
Users are advised to update to Valtimo versions 12.32.0 or 13.23.0, depending on the affected component.
