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."}], "lastModified": "2025-10-07T14:39:29.373", "configurations": [{"nodes": [{"negate": false, "cpeMatch": [{"criteria": "cpe:2.3:a:argoproj:argo_cd:*:*:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "CDA16487-4630-4646-9952-32E096B64251", "versionEndIncluding": "1.8.7", "versionStartIncluding": "1.2.0"}, {"criteria": "cpe:2.3:a:argoproj:argo_cd:*:*:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "FD4B38D5-4CEC-4C24-AD81-92B9DA4426AC", "versionEndExcluding": "2.14.20", "versionStartIncluding": "2.0.0"}, {"criteria": "cpe:2.3:a:argoproj:argo_cd:*:*:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "E7FEAEBF-40B8-40E4-B34B-2785B0FEAFEB", "versionEndExcluding": "3.0.19", "versionStartIncluding": "3.0.0"}, {"criteria": "cpe:2.3:a:argoproj:argo_cd:*:*:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "AFF4E847-D3D6-457A-A47B-98799D28E20E", "versionEndExcluding": "3.1.8", "versionStartIncluding": "3.1.0"}, {"criteria": "cpe:2.3:a:argoproj:argo_cd:3.2.0:rc1:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "247C0721-E494-4732-BF53-F249C574A702"}], "operator": "OR"}]}], "sourceIdentifier": "security-advisories@github.com"}
