The issue is related to the use of insufficiently random values in parameters in Oauth2/OIDC login flows, making it possible for an attacker to gain admin access to Argo CD. The attacks are difficult to accomplish but can have a high impact. The vulnerabilities are due to the use of a relatively-predictable seed in a non-cryptographically-secure pseudo-random number generator, and in some cases, using too short a value made the entropy even less sufficient. The vulnerable parameters include the `state` parameter, `code verifier` parameter, and `nonce` parameter.
