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.","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-703"],"references":["https://github.com/argoproj/argo-cd/commit/5c466a4e39802e059e75c0008ae7b7b8e842538f","https://github.com/argoproj/argo-cd/security/advisories/GHSA-f9gq-prrc-hrhc","https://github.com/argoproj/argo-cd/security/advisories/GHSA-f9gq-prrc-hrhc"],"products":["argoproj:argo_cd"],"source":"nvd","synced_at":"2026-10-19T22:11:26.888974865+00:00"},"epss":{"cve":"CVE-2025-59531","score":0.00588,"percentile":0.47825,"date":"2026-10-25"},"kev":null,"osv":[{"id":"GHSA-f9gq-prrc-hrhc","url":"https://osv.dev/vulnerability/GHSA-f9gq-prrc-hrhc","summary":"Unauthenticated argocd-server panic via a malicious Bitbucket-Server webhook payload","modified":"2025-10-23T20:21:58Z","packages":[{"ecosystem":"Go","name":"github.com/argoproj/argo-cd","purl":"pkg:golang/github.com/argoproj/argo-cd","ranges":[">=1.2.0 <=1.8.7"],"fixed":[]},{"ecosystem":"Go","name":"github.com/argoproj/argo-cd/v2","purl":"pkg:golang/github.com/argoproj/argo-cd/v2","ranges":[">=2.0.0-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-2025-3993","url":"https://osv.dev/vulnerability/GO-2025-3993","summary":"Unauthenticated argocd-server panic via a malicious Bitbucket-Server webhook payload in github.com/argoproj/argo-cd","modified":"2026-04-20T19:00:21.450402Z","packages":[{"ecosystem":"Go","name":"github.com/argoproj/argo-cd","purl":"pkg:golang/github.com/argoproj/argo-cd","ranges":[">=1.2.0"],"fixed":[]},{"ecosystem":"Go","name":"github.com/argoproj/argo-cd/v2","purl":"pkg:golang/github.com/argoproj/argo-cd/v2","ranges":["<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).
