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

**Signal:** Critical, preconditions apply. Severe if exploited, but exploitation needs conditions that may not apply to you. (Computed from CISA KEV, EPSS and CVSS; not an editorial verdict.)

## Should you act?

- No confirmed exploitation. It is not in CISA’s KEV catalog and CISA’s SSVC assessment records no known exploitation. That can change quickly after a public write-up; re-check if you are affected.
- EPSS 0.8% , percentile 57: FIRST’s model estimates a 0.8% chance of exploitation activity in the next 30 days, higher than 57% of all scored CVEs (moderate). EPSS is a probability, not a verdict.
- Needs an account (high (admin)). Exposure depends on who can log in.
- Only applies if your dependency tree includes com.ritense.valtimo:document (Maven) >= 12.0.0, < 12.32.0, fixed in 12.32.0 ; com.ritense.valtimo:case (Maven) >= 13.0.0, < 13.23.0, fixed in 13.23.0 ; com.ritense.valtimo:contract (Maven) >= 13.4.0, < 13.23.0, fixed in 13.23.0 . Check your lockfile, including transitive dependencies.

## What it is

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.

## Affected packages

- Maven `com.ritense.valtimo:document` >= 12.0.0, < 12.32.0 → fixed: 12.32.0
- Maven `com.ritense.valtimo:case` >= 13.0.0, < 13.23.0 → fixed: 13.23.0
- Maven `com.ritense.valtimo:contract` >= 13.4.0, < 13.23.0 → fixed: 13.23.0

## Affected products (CVE record)

- valtimo-platform valtimo: < 13.23.0
- com.ritense.valtimo case: >= 13.0.0, < 13.23.0
- com.ritense.valtimo contract: >= 13.4.0, < 13.23.0
- com.ritense.valtimo document: >= 12.0.0, < 12.32.0

## Severity

- GitHub_M CVSS 3.1: 9.1 `CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:C/C:H/I:H/A:H`
- GitHub CVSS 3.1: 9.1 `CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:C/C:H/I:H/A:H`

## Exploitation

- CISA KEV: not listed (no confirmed in-the-wild exploitation known to CISA).
- CISA SSVC assessment: exploitation none , automatable no , technical impact total .
- FIRST EPSS (model of 2026-10-21): 0.82% probability of exploitation activity in the next 30 days; percentile 57.
