How to fix?

Upgrade github.com/argoproj/argo-cd/v2/util/io/files to version 2.1.15, 2.2.9, 2.3.4 or higher.


github.com/argoproj/argo-cd/v2/util/io/files is a declarative, GitOps continuous delivery tool for Kubernetes.

Affected versions of this package are vulnerable to UNIX Symbolic Link (Symlink) Following. A malicious Argo CD user with write access for a repository that is used in a directory-type Application may commit a symlink that points to an out-of-bounds file.


  1. If the target file is a valid JSON or YAML manifest file, and the resource is allowed in the Application, the attacker can read the contents of that manifest file. (In versions <2.3.2, <2.2.8, and <2.1.14, the attacker may read the contents of the file even if the resource is not allowed in the Application).

  2. If the target file is valid JSON but is not a manifest file, the attacker may read the contents of the file.

  3. If the target file is not valid JSON or YAML, the attacker may read partial file contents (usually just the first character of the file).
