Versions 1.2.0 through 1.8.7, 2.0.0-rc1 through 2.14.19, 3.0.0-rc1 through 3.2.0-rc1, 3.1.7 and 3.0.18 are vulnerable to malicious API requests which can crash the API server and cause denial of service to legitimate clients. Without a configured webhook.bitbucketserver.secret, Argo CD's /api/webhook endpoint crashes when receiving a malformed Bitbucket Server payload (non-array repository.links.clone field). A single unauthenticated request triggers CrashLoopBackOff, and targeting all replicas causes complete API outage. This issue is fixed in versions 2.14.20, 3.2.0-rc2, 3.1.8 and 3.0.19.","state":0,"publishedAt":"2025-10-01T20:49:35.428+00:00","modifiedAt":"2025-10-02T15:54:24.95+00:00","affected":[{"ecosystem":"Vendor product","name":"argo-cd","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"argoproj\",\n                    \"product\": \"argo-cd\",\n                    \"versions\": [\n                        {\n                            \"version\": \">= 1.2.0, <= 1.8.7\",\n                            \"status\": \"affected\"\n                        },\n                        {\n                            \"version\": \">= 2.0.0-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-f9gq-prrc-hrhc","https://github.com/argoproj/argo-cd/commit/5c466a4e39802e059e75c0008ae7b7b8e842538f"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2025-59531","license":"CVE Program Terms of Use","key":"cve-program:CVE-2025-59531","identifiers":["CVE-2025-59531"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
