Vulnerability details
Argo CD is a declarative, GitOps continuous delivery tool for Kubernetes. All unpatched versions of Argo CD starting with 1.0.0 are vulnerable to an improper access control bug, allowing a malicious user to potentially escalate their privileges to admin-level. Versions…
more
starting with 0.8.0 and 0.5.0 contain limited versions of this issue. To perform exploits, an authorized Argo CD user must have push access to an Application's source git or Helm repository or `sync` and `override` access to an Application. Once a user has that access, different exploitation levels are possible depending on their other RBAC privileges. A patch for this vulnerability has been released in Argo CD versions 2.3.2, 2.2.8, and 2.1.14. Some mitigation measures are available but do not serve as a substitute for upgrading. To avoid privilege escalation, limit who has push access to Application source repositories or `sync` + `override` access to Applications; and limit which repositories are available in projects where users have `update` access to Applications. To avoid unauthorized resource inspection/tampering, limit who has `delete`, `get`, or `action` access to Applications.

Per-CVE control mapping for this CVE has not run yet; the list below is derived from the weakness types (CWEs) cited in the NVD entry.
Requiring attribute association with information prevents authorization from being performed without necessary security or privacy context.
Mandates authorization checks before permitting access or data processing via external systems.
The control provides a mechanism for authorized users to determine authorization matches, preventing sharing without proper authorization verification.
Session auditing enables detection of unauthorized exposure or access to sensitive information during user activities.
Sanitizing equipment to remove specified information before off-site maintenance prevents exposure of sensitive information to unauthorized actors such as external maintenance personnel.
Requiring detailed, requestable records of every PII disclosure directly aids detection of unauthorized exposures of sensitive information.
Ensures missing authorization mechanisms for critical data functions are identified and remediated via policy.
Annual reviews and proposal scrutiny detect and block matching programs that would expose sensitive data to unauthorized recipients or systems.
