CVE-2025-23216: Argo CD does not scrub secret values from patch errors
(updated )
A vulnerability was discovered in Argo CD that exposed secret values in error messages and the diff view when an invalid Kubernetes Secret resource was synced from a repository.
The vulnerability assumes the user has write access to the repository and can exploit it, either intentionally or unintentionally, by committing an invalid Secret to repository and triggering a Sync. Once exploited, any user with read access to Argo CD can view the exposed secret data.
