## What is CVE-2026-71471?

CVE-2026-71471 is a critical code injection vulnerability in Red Hat Advanced Cluster Management for Kubernetes 2.11, published on 12 Aug 2026. An attacker needs administrator access to exploit it, with no action from the victim.

### Official description

A flaw was found in acm-search-v2-rhel9. An attacker with administrative privileges on the hub cluster, specifically with patch access to the Search Custom Resource (CR), could exploit a vulnerability in the `Collector.ImageOverride` field. This allows the attacker to deploy an arbitrary container image across all managed clusters. The consequence is remote code execution (RCE), enabling the attacker to execute commands and potentially access sensitive information across the entire fleet of managed clusters.

Weakness: CWE-829 (Inclusion of Functionality from Untrusted Control Sphere)

Check this codebase for CVE-2026-71471 and fix it if it is affected.

What it is: CVE-2026-71471 is a critical code injection vulnerability in Red Hat Advanced Cluster Management for Kubernetes 2.11, published on 12 Aug 2026. An attacker needs administrator access to exploit it, with no action from the victim.
Exploitation: There is no known exploitation of CVE-2026-71471 in the wild and no public exploit code.

Affected product: Red Hat Advanced Cluster Management for Kubernetes 2.11. No package-level version data is available, so check the vendor advisory linked from the reference page.

Task:
1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.
2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.
3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.
4. Run the tests and summarise what changed and why.
5. If nothing in the project is affected, say so and change nothing.
