For example, in the `secretToRepoCred` function. The issue manifests as a concurrent map access panic:\n\n```\nconcurrent map read and map write\n...\ngoroutine 1104 [running]:\ngithub.com/argoproj/argo-cd/v2/util/db.(*secretsRepositoryBackend).secretToRepoCred(0xc000e50ea8?, 0xc000c65540)\n        /go/src/github.com/argoproj/argo-cd/util/db/repository_secrets.go:404 +0x31e\n```\n\nThe race condition occurs due to:\n1. Concurrent repository credential operations (create/update/delete) accessing the same map\n2. Kubernetes informer re-syncs happening simultaneously\n3. Background watchers updating the same secret data\n4. No mutex protection for map access\n\nA valid API token with `repositories` resource permissions (`create`, `update`, or `delete` actions) is required to trigger the race condition.\n\n### Impact\n\nThis vulnerability causes the entire Argo CD server to crash and become unavailable. Attackers can repeatedly and continuously trigger the race condition to maintain a denial-of-service state, disrupting all GitOps operations. Default ArgoCD configuration is vulnerable.\n\nThe affected code was originally introduced in [PR #6103](https://github.com/argoproj/argo-cd/pull/6103) and released in [v2.1.0](https://github.com/argoproj/argo-cd/releases/tag/v2.1.0).\n\nThis data race was addressed by deep-copying the `Secret` objects before reading/writing.\n\n### Credits\n\nThis vulnerability was found, reported and fixed by:\n\n@thevilledev\n\nThe Argo team would like to thank him for his responsible disclosure and constructive communications during the resolve of this issue.","affected":[{"package":{"name":"github.com/argoproj/argo-cd/v2","ecosystem":"Go","purl":"pkg:golang/github.com/argoproj/argo-cd/v2"},"ranges":[{"type":"SEMVER","events":[{"introduced":"2.1.0"},{"fixed":"2.14.20"}]}],"database_specific":{"last_known_affected_version_range":"<= 2.14.19","source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2025/09/GHSA-g88p-r42r-ppp9/GHSA-g88p-r42r-ppp9.json"}},{"package":{"name":"github.com/argoproj/argo-cd/v3","ecosystem":"Go","purl":"pkg:golang/github.com/argoproj/argo-cd/v3"},"ranges":[{"type":"SEMVER","events":[{"introduced":"3.2.0-rc1"},{"fixed":"3.2.0-rc2"}]}],"versions":["3.2.0-rc1"],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2025/09/GHSA-g88p-r42r-ppp9/GHSA-g88p-r42r-ppp9.json"}},{"package":{"name":"github.com/argoproj/argo-cd/v3","ecosystem":"Go","purl":"pkg:golang/github.com/argoproj/argo-cd/v3"},"ranges":[{"type":"SEMVER","events":[{"introduced":"3.1.0-rc1"},{"fixed":"3.1.8"}]}],"database_specific":{"last_known_affected_version_range":"<= 3.1.7","source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2025/09/GHSA-g88p-r42r-ppp9/GHSA-g88p-r42r-ppp9.json"}},{"package":{"name":"github.com/argoproj/argo-cd/v3","ecosystem":"Go","purl":"pkg:golang/github.com/argoproj/argo-cd/v3"},"ranges":[{"type":"SEMVER","events":[{"introduced":"3.0.0-rc1"},{"fixed":"3.0.19"}]}],"database_specific":{"last_known_affected_version_range":"<= 3.0.18","source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2025/09/GHSA-g88p-r42r-ppp9/GHSA-g88p-r42r-ppp9.json"}}],"references":[{"type":"WEB","url":"https://github.com/argoproj/argo-cd/security/advisories/GHSA-g88p-r42r-ppp9"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2025-55191"},{"type":"WEB","url":"https://github.com/argoproj/argo-cd/pull/6103"},{"type":"WEB","url":"https://github.com/argoproj/argo-cd/commit/701bc50d01c752cad96185f848088d287a97c7b7"},{"type":"PACKAGE","url":"https://github.com/argoproj/argo-cd"},{"type":"WEB","url":"https://pkg.go.dev/vuln/GO-2025-3994"}],"database_specific":{"cwe_ids":["CWE-362"],"github_reviewed":true,"github_reviewed_at":"2025-09-30T18:01:48Z","nvd_published_at":"2025-09-30T23:15:29Z","severity":"MODERATE"},"severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H"}]}
