CVE-2023-25163Network attack vector

Repository credential disclosure via unsanitized error formatting

Published Feb 8, 2023 · Updated Mar 10, 2025

Information disclosure in Argo CD 2.6.0-rc1 through 2.6.0 allows remote authenticated users to read repository credentials. The validateRepo path formatted the entire Repository object into an error, so secret fields such as GitHub App private keys reached API responses and server logs. Reachability requires applications create or update RBAC access and a repository-access error; successful triggering discloses stored credentials without changing data or interrupting service.
