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.","provenance":"source","from":"CVE.org"},"cvss":{"score":7.5,"severity":"HIGH","version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","provenance":"source","from":"CVE.org CNA"},"epss":{"score":0.00588,"percentile":0.47979,"provenance":"source"},"cwes":[{"id":"CWE-703","name":"Improper Check or Handling of Exceptional Conditions"}],"references":[{"url":"https://github.com/argoproj/argo-cd/security/advisories/GHSA-f9gq-prrc-hrhc","tags":["x_refsource_CONFIRM"]},{"url":"https://github.com/argoproj/argo-cd/commit/5c466a4e39802e059e75c0008ae7b7b8e842538f","tags":["x_refsource_MISC"]}],"priority":{"score":14.8,"factors":[{"name":"EPSS percentile","points":9.6},{"name":"CVSS severity","points":5.25}]},"vendorSlug":"argoproj","affectedVersions":[{"vendor":"argoproj","product":"argo-cd","versions":[">= 1.2.0, <= 1.8.7",">= 2.0.0-rc1, < 2.14.20",">= 3.2.0-rc1, < 3.2.0-rc2",">= 3.1.0-rc1, < 3.1.8",">= 3.0.0-rc1, < 3.0.19"]}],"affected":[{"ecosystem":"Go","package":"github.com/argoproj/argo-cd","vulnerableRanges":[">=1.2.0, <=1.8.7",">=1.2.0"],"patched":[],"from":["GHSA-f9gq-prrc-hrhc","GO-2025-3993"],"provenance":"source"},{"ecosystem":"Go","package":"github.com/argoproj/argo-cd/v2","vulnerableRanges":[">=2.0.0-rc1, <2.14.20","<2.14.20"],"patched":["2.14.20"],"from":["GHSA-f9gq-prrc-hrhc","GO-2025-3993"],"provenance":"source"},{"ecosystem":"Go","package":"github.com/argoproj/argo-cd/v3","vulnerableRanges":[">=3.2.0-rc1, <3.2.0-rc2",">=3.1.0-rc1, <3.1.8",">=3.0.0-rc1, <3.0.19"],"patched":["3.2.0-rc2","3.1.8","3.0.19"],"from":["GHSA-f9gq-prrc-hrhc","GO-2025-3993"],"provenance":"source"}],"euvd":{"id":"EUVD-2025-31767","exploited":false,"provenance":"source"}}
