SCA: security update for github.com/argoproj/argo-cd/v2, github.com/argoproj/argo-cd/v3 (GHSA-fmxq-cgp8-87wp)

critical Tenable Cloud Security Plugin ID 474715

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 2.10.0 until 3.3.15,
 3.4.10, 3.5.4, and 3.6.0-rc2, Argo CD creates PostDelete resource hooks without applying the AppProject
 destination and resource authorization checks used during ordinary synchronization. The omitted checks
 include cluster-scoped and namespaced resource allow/deny lists. A user who can write to an Application's
 Git repository can commit a delete hook targeting a forbidden namespace, server, group, kind, or resource
 name, and deletion of the Application causes the application-controller to create that resource with its
 destination-cluster credentials. The reachable impact is bounded by the controller's cluster access but
 can include cluster-scoped resources, disallowed namespaces, persistent hook objects, and secondary
 objects created by a hook Job. PreSync, Sync, PostSync, and SyncFail hooks continue to use the normal
 project checks. This issue is fixed in versions 3.3.15, 3.4.10, 3.5.4, and 3.6.0-rc2. (CVE-2026-77459)

Solution

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