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.","cvss_v4":null,"cvss_v3":{"version":"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},"cwes":["CWE-248","CWE-703"],"references":["https://github.com/argoproj/argo-cd/commit/1a023f1ca7fe4ec942b4b6696804988d5a632baf","https://github.com/argoproj/argo-cd/security/advisories/GHSA-gpx4-37g2-c8pv","https://github.com/argoproj/argo-cd/security/advisories/GHSA-gpx4-37g2-c8pv"],"products":["argoproj:argo_cd"],"source":"nvd","synced_at":"2026-10-19T22:11:26.888974865+00:00"},"epss":{"cve":"CVE-2025-59538","score":0.09364,"percentile":0.95359,"date":"2026-10-25"},"kev":null,"osv":[{"id":"GHSA-gpx4-37g2-c8pv","url":"https://osv.dev/vulnerability/GHSA-gpx4-37g2-c8pv","summary":"Argo CD Unauthenticated Remote DoS via malformed Azure DevOps git.push webhook","modified":"2025-10-23T20:29:02Z","packages":[{"ecosystem":"Go","name":"github.com/argoproj/argo-cd/v2","purl":"pkg:golang/github.com/argoproj/argo-cd/v2","ranges":[">=2.9.0-rc1 <2.14.20"],"fixed":["2.14.20"]},{"ecosystem":"Go","name":"github.com/argoproj/argo-cd/v3","purl":"pkg:golang/github.com/argoproj/argo-cd/v3","ranges":[">=3.2.0-rc1 <3.2.0-rc2"],"fixed":["3.2.0-rc2"]},{"ecosystem":"Go","name":"github.com/argoproj/argo-cd/v3","purl":"pkg:golang/github.com/argoproj/argo-cd/v3","ranges":[">=3.1.0-rc1 <3.1.8"],"fixed":["3.1.8"]},{"ecosystem":"Go","name":"github.com/argoproj/argo-cd/v3","purl":"pkg:golang/github.com/argoproj/argo-cd/v3","ranges":[">=3.0.0-rc1 <3.0.19"],"fixed":["3.0.19"]}]},{"id":"GO-2025-3995","url":"https://osv.dev/vulnerability/GO-2025-3995","summary":"Argo CD Unauthenticated Remote DoS via malformed Azure DevOps git.push webhook in github.com/argoproj/argo-cd","modified":"2025-10-23T16:42:17.824493Z","packages":[{"ecosystem":"Go","name":"github.com/argoproj/argo-cd","purl":"pkg:golang/github.com/argoproj/argo-cd","ranges":["all versions"],"fixed":[]},{"ecosystem":"Go","name":"github.com/argoproj/argo-cd/v2","purl":"pkg:golang/github.com/argoproj/argo-cd/v2","ranges":[">=2.9.0-rc1 <2.14.20"],"fixed":["2.14.20"]},{"ecosystem":"Go","name":"github.com/argoproj/argo-cd/v3","purl":"pkg:golang/github.com/argoproj/argo-cd/v3","ranges":[">=3.0.0-rc1 <3.0.19",">=3.1.0-rc1 <3.1.8",">=3.2.0-rc1 <3.2.0-rc2"],"fixed":["3.0.19","3.1.8","3.2.0-rc2"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
