Argo CD Project Details API Repository Credential Exposure
CVE-2025-55190 is an information disclosure vulnerability in Argo CD caused by insufficient access control enforcement in the project details API endpoint, /api/v1/projects/{project}/detailed. In affected versions, API tokens with project-level permissions, including tokens that only have projects, get access or standard application-management permissions, can retrieve sensitive repository credentials associated with the project. The exposed data includes repository usernames and passwords used to access private Git and related repositories. The flaw stems from the endpoint returning credential material in its response without properly restricting or filtering it based on the caller’s effective authorization.

get permissions, especially broadly scoped global permissions such as p, role/user, projects, get, *, allow. Limit access to the /api/v1/projects/{project}/detailed endpoint where feasible, audit token issuance and RBAC mappings, monitor for suspicious access to project detail APIs, and proactively rotate repository credentials that may have been disclosed.Remediation
Patch, then assume compromise.
