# CVE-2026-32613: Spinnaker: RCE via expression parsing due to unrestricted context handling

**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 0.7% , percentile 51: FIRST’s model estimates a 0.7% chance of exploitation activity in the next 30 days, higher than 51% of all scored CVEs (moderate). EPSS is a probability, not a verdict.
- Needs an account (low (any account)). Exposure depends on who can log in.
- Only applies if your dependency tree includes io.spinnaker.echo:echo-pipelinetriggers (Maven) >= 2026.0-0, < 2026.0.1, fixed in 2026.0.1 ; io.spinnaker.echo:echo-pipelinetriggers (Maven) >= 2025.4-0, < 2025.4.2, fixed in 2025.4.2 ; io.spinnaker.echo:echo-pipelinetriggers (Maven) < 2025.3.2, fixed in 2025.3.2 . Check your lockfile, including transitive dependencies.

## What it is

Spinnaker is an open source, multi-cloud continuous delivery platform. Echo like some other services, uses SPeL (Spring Expression Language) to process information - specifically around expected artifacts. In versions prior to 2026.1.0, 2026.0.1, 2025.4.2, and 2025.3.2, unlike orca, it was NOT restricting that context to a set of trusted classes, but allowing FULL JVM access. This enabled a user to use arbitrary java classes which allow deep access to the system. This enabled the ability to invoke commands, access files, etc. Versions 2026.1.0, 2026.0.1, 2025.4.2, and 2025.3.2 contain a patch. As a workaround, disable echo entirely.

## Affected packages

- Maven `io.spinnaker.echo:echo-pipelinetriggers` >= 2026.0-0, < 2026.0.1 → fixed: 2026.0.1
- Maven `io.spinnaker.echo:echo-pipelinetriggers` >= 2025.4-0, < 2025.4.2 → fixed: 2025.4.2
- Maven `io.spinnaker.echo:echo-pipelinetriggers` < 2025.3.2 → fixed: 2025.3.2

## Affected products (CVE record)

- spinnaker spinnaker: < 2026.0.1, < 2025.4.2, < 2025.3.2, < 2026.1.0

## Severity

- GitHub_M CVSS 3.1: 10 `CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H`
- GitHub CVSS 3.1: 9.9 `CVSS:3.1/AV:N/AC:L/PR:L/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): 0.66% probability of exploitation activity in the next 30 days; percentile 51.
