Echo: github.com/argoproj/argo-cd/v3: security update to 3.3.15

high Tenable Self-Hosted Container Security Plugin ID 474335

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - Argo CD is a declarative, GitOps continuous delivery tool for Kubernetes. From 2.11.0 until 3.3.15,
 3.4.10, 3.5.4, and 3.6.0-rc2, the Argo CD repo-server is vulnerable to command injection when it clones,
 tests, or fetches an SSH Git repository configured with a proxy URL. The proxy host and port are embedded
 in an SSH ProxyCommand that is executed through a shell without neutralizing shell metacharacters. A user
 who can create or update a repository or repository credential template can supply a crafted proxy host to
 execute commands in the repo-server and access its Git, Helm, and OCI credentials. This issue is fixed in
 versions 3.3.15, 3.4.10, 3.5.4, and 3.6.0-rc2. (CVE-2026-55797)

Solution

Update the github.com/argoproj/argo-cd/v3 library and its related packages to version 3.3.15 or later.
