{"id":"CVE-2025-59538","summary":"Argo CD is Vulnerable to Unauthenticated Remote DoS via malformed Azure DevOps git.push webhook","details":"Argo CD is a declarative, GitOps continuous delivery tool for Kubernetes. 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.","aliases":["BIT-argo-cd-2025-59538","GHSA-gpx4-37g2-c8pv","GO-2025-3995"],"modified":"2026-04-26T03:47:00.375691Z","published":"2025-10-01T21:09:08.870Z","related":["SUSE-SU-2025:3799-1","openSUSE-SU-2025:15666-1"],"database_specific":{"cwe_ids":["CWE-248","CWE-703"],"cna_assigner":"GitHub_M","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2025/59xxx/CVE-2025-59538.json"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2025/59xxx/CVE-2025-59538.json"},{"type":"ADVISORY","url":"https://github.com/argoproj/argo-cd/security/advisories/GHSA-gpx4-37g2-c8pv"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2025-59538"},{"type":"FIX","url":"https://github.com/argoproj/argo-cd/commit/1a023f1ca7fe4ec942b4b6696804988d5a632baf"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/argoproj/argo-cd","events":[{"introduced":"226a670fe6b3c6769ff6d18e6839298a58e4577d"},{"fixed":"132be88e674fbdb222e38f9a15edb5b512904cd9"}]}],"versions":["v3.0.0","v3.0.0-rc1","v3.0.0-rc2","v3.0.0-rc3","v3.0.0-rc4","v3.0.0-rc5","v3.0.0-rc6","v3.0.1","v3.0.10","v3.0.11","v3.0.12","v3.0.13","v3.0.14","v3.0.15","v3.0.16","v3.0.17","v3.0.18","v3.0.2","v3.0.3","v3.0.4","v3.0.5","v3.0.6","v3.0.7","v3.0.8","v3.0.9"],"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2025-59538.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H"}]}
