Code injection in spring-cloud-netflix-hystrix-dashboard

CVE-2021-22053GHSA-gx3f-hq7p-8fxv

What to do

Vendor fix available. Upgrade each affected package to the fixed version on its release line (org.springframework.cloud:spring-cloud-netflix-hystrix-dashboard 2.2.10.RELEASE), redeploy, then verify what is actually installed.

This page has no inventory attached, so it cannot say whether you are affected. A vendor fix is not proof that your deployment is fixed.

Source description

As published by the source; long descriptions are shortened.

Applications using the spring-cloud-netflix-hystrix-dashboard expose a way to execute code submitted within the request URI path during the resolution of view templates. When a request is made at /hystrix/monitor;[user-provided data], the path elements following hystrix/monitor are being evaluated as SpringEL expressions, which can lead to code execution.

# Patch Next advisory brief: CVE-2021-22053

Advisory: Code injection in spring-cloud-netflix-hystrix-dashboard
IDs: CVE-2021-22053, GHSA-gx3f-hq7p-8fxv
Record: https://patchnext.com/advisories/cve-2021-22053 (revision 1, source checked 26 Oct 2026, 16:07 UTC)
Inventory: none attached. This brief comes from a public page and does not say whether any deployment is affected.
Severity: High (CVSS 7.6)
Exploitation: no confirmed exploitation recorded. Patch Next confirms exploitation only from CISA KEV.
Vendor response: Vendor fix available; fixed versions by package: org.springframework.cloud:spring-cloud-netflix-hystrix-dashboard 2.2.10.RELEASE. A vendor fix does not mean a deployment is fixed.

## Affected components
- Maven org.springframework.cloud:spring-cloud-netflix-hystrix-dashboard: affected <= 2.2.9.RELEASE; fixed in 2.2.10.RELEASE

## Suggested inspection (read-only)
- Maven org.springframework.cloud:spring-cloud-netflix-hystrix-dashboard: check the installed version with your package manager.

## Supported action
Upgrade each affected component to a fixed version on its release line. For a transitive dependency, upgrade the parent package or add an override or constraint, then regenerate the lockfile. Redeploy every environment that ran an affected version.

## Required regression checks
- Run the test suite and a production build.
- Exercise the features that depend on org.springframework.cloud:spring-cloud-netflix-hystrix-dashboard.
- Repeat the inspection and confirm that only fixed versions remain installed.

## Rollback considerations
- Keep the previous lockfile and deployment artifact. Rolling back reinstates the vulnerable version, so apply any documented mitigation while you fix forward.

## Unresolved questions
- Which deployments run an affected version?
- Exploitation status can change. Check again before lowering the priority.
- Mark the work resolved only after the fixed version is verified in production.
