For versions 2.9.0-rc1 through 2.14.19, 3.0.0-rc1 through 3.2.0-rc1, 3.1.6 and 3.0.17, when the webhook.azuredevops.username and webhook.azuredevops.password are not set in the default configuration, the /api/webhook endpoint crashes the entire argocd-server process when it receives an Azure DevOps Push event whose JSON array resource.refUpdates is empty. The slice index [0] is accessed without a length check, causing an index-out-of-range panic. A single unauthenticated HTTP POST is enough to kill the process. This issue is resolved in versions 2.14.20, 3.2.0-rc2, 3.1.8 and 3.0.19.","state":0,"publishedAt":"2025-10-01T21:09:08.87+00:00","modifiedAt":"2025-10-02T15:54:11.49+00:00","affected":[{"ecosystem":"Vendor product","name":"argo-cd","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"argoproj\",\n                    \"product\": \"argo-cd\",\n                    \"versions\": [\n                        {\n                            \"version\": \">= 2.9.0-rc1, < 2.14.20\",\n                            \"status\": \"affected\"\n                        },\n                        {\n                            \"version\": \">= 3.2.0-rc1, < 3.2.0-rc2\",\n                            \"status\": \"affected\"\n                        },\n                        {\n                            \"version\": \">= 3.1.0-rc1, < 3.1.8\",\n                            \"status\": \"affected\"\n                        },\n                        {\n                            \"version\": \">= 3.0.0-rc1, < 3.0.19\",\n                            \"status\": \"affected\"\n                        }\n                    ]\n                }"}],"metrics":[{"system":"CVSS 3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","score":7.5,"severity":"HIGH"}],"references":["https://github.com/argoproj/argo-cd/security/advisories/GHSA-gpx4-37g2-c8pv","https://github.com/argoproj/argo-cd/commit/1a023f1ca7fe4ec942b4b6696804988d5a632baf"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2025-59538","license":"CVE Program Terms of Use","key":"cve-program:CVE-2025-59538","identifiers":["CVE-2025-59538"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
