## What is CVE-2026-113708?

CVE-2026-113708 is a critical vulnerability in argoproj argo-cd, published on 20 Oct 2026. 

### Official description

Argo CD is a declarative, GitOps continuous delivery tool for Kubernetes. From 2.7.0 until 3.3.15, 3.4.10, 3.5.4, and 3.6.0-rc2, Kustomize passes ref or version query values from remote resource, base, or component URLs to git fetch without an end-of-options separator. A leading-hyphen value can be parsed as --upload-pack and execute a command inside argocd-repo-server when the remote uses a local transport such as file://. Git does not run the supplied command for an https:// remote. The local transport does not leave the pod, so blocking repo-server egress does not prevent the execution. The command runs as the repo-server user, can read repository credentials and other process-accessible data, and can return output through manifest-generation errors. An attacker can commit a Kustomization to a Git repository that an Application builds or upload files through POST /api/v1/applications/manifestsWithFiles, also exposed by argocd app diff --local --server-side-generate. The upload path requires only Application get permission on an existing Application, without Application update or sync permission or repository write access. Kustomize 5.0.0 introduced acceptance of file://, whereas 4.5.7 rejects that transport; replacing the affected Kustomize with a newer version alone does not correct the missing option separator. This issue is fixed in versions 3.3.15, 3.4.10, 3.5.4, and 3.6.0-rc2.

Weakness: CWE-88 (Improper Neutralization of Argument Delimiters in a Command)

Check this codebase for CVE-2026-113708 and fix it if it is affected.

What it is: CVE-2026-113708 is a critical vulnerability in argoproj argo-cd, published on 20 Oct 2026. 
Exploitation: There is no known exploitation of CVE-2026-113708 in the wild and no public exploit code.

Affected packages and fixed versions:
- argo-cd (Bitnami): affected from 2.7.0; fixed in 3.3.15, 3.4.10, 3.5.4

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.
