CVE-2026-42555
Valtimo: SpEL injection via StandardEvaluationContext allows Remote Code Execution by admin users
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.

Valtimo has SpEL injection via StandardEvaluationContext that allows Remote Code Execution by admin users
Summary
Multiple classes 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.
Impact
An attacker with ADMIN credentials can:
- Execute arbitrary OS commands via
T(java.lang.Runtime).getRuntime().exec('...') - Exfiltrate all environment variables (database passwords, API keys, Keycloak secrets) via
T(java.lang.System).getenv() - Read JVM system properties via
T(java.lang.System).getProperties() - Load arbitrary classes via
T(java.lang.Class).forName('...')
Affected Components
1. DocumentMigrationService (since 12.0.0)
Exploitable through the document migration REST API:
POST /api/management/v1/document-definition/migratePOST /api/management/v1/document-definition/migration/conflicts
The malicious SpEL expression is supplied in the source or target field of a DocumentMigrationPatch object in the request body, using the ${...} template syntax.
- In 12.x:
com.ritense.document.service.DocumentMigrationService#handleSpelExpression(document module) - In 13.x: same class, moved to the case module
2. Condition (since 13.4.0)
Exploitable through any admin-configured widget, dashboard, or feature that uses the Condition framework. The SpEL expression is supplied in the value field of a condition's JSON configuration.
com.ritense.valtimo.contract.conditions.Condition#resolveValue(contract module)
This component has a significantly wider attack surface than DocumentMigrationService, as conditions are used across many modules.
Remediation
Replace StandardEvaluationContext with SimpleEvaluationContext in both affected classes, which disallows Java type references and arbitrary method invocation:
val evaluationContext = SimpleEvaluationContext
.forPropertyAccessors(MapAccessor(), jsonPropertyAccessor)
.build()
