Argo Continuous Delivery Security Vulnerabilities

CVE-2018-21034

In Argo versions prior to v1.5.0-rc1, it was possible for authenticated Argo users to submit API calls to retrieve secrets and other manifests which were stored within git.

CVE-2020-11576

Fixed in v1.5.1, Argo version v1.5.0 was vulnerable to a user-enumeration vulnerability which allowed attackers to determine the usernames of valid (non-SSO) accounts because /api/v1/session returned 401 for an existing username and 404 otherwise.

CVE-2020-8826

As of v1.5.0, the Argo web interface authentication system issued immutable tokens. Authentication tokens, once issued, were usable forever without expiration—there was no refresh or forced re-authentication.

CVE-2020-8827

As of v1.5.0, the Argo API does not implement anti-automation measures such as rate limiting, account lockouts, or other anti-bruteforce measures. Attackers can submit an unlimited number of authentication attempts without consequence.

CVE-2020-8828

As of v1.5.0, the default admin password is set to the argocd-server pod name. For insiders with access to the cluster or logs, this issue could be abused for privilege escalation, as Argo has privileged roles. A malicious insider is the most realistic threat, but pod names are not meant to be kept...

CVE-2021-23135

Exposure of System Data to an Unauthorized Control Sphere vulnerability in web UI of Argo CD allows attacker to cause leaked secret data into web UI error messages and logs. This issue affects Argo CD 1.8 versions prior to 1.8.7; 1.7 versions prior to 1.7.14.

CVE-2021-23347

The package github.com/argoproj/argo-cd/cmd before 1.7.13, from 1.8.0 and before 1.8.6 are vulnerable to Cross-site Scripting (XSS) the SSO provider connected to Argo CD would have to send back a malicious error message containing JavaScript to the user.

CVE-2021-26921

In util/session/sessionmanager.go in Argo CD before 1.8.4, tokens continue to work even when the user account is disabled.

CVE-2023-25163

Argo CD is a declarative, GitOps continuous delivery tool for Kubernetes. All versions of Argo CD starting with v2.6.0-rc1 have an output sanitization bug which leaks repository access credentials in error messages. These error messages are visible to the user, and they are logged. The error messag...

CVE-2023-40029
