{"apiVersion":"1.0","identifier":"CVE-2026-73840","description":"OpenChoreo is a complete, open-source developer platform for Kubernetes. Prior to 1.0.3, 1.1.3, and 1.2.0-rc.2, the POST /api/v1alpha1/autobuild endpoint in internal/openchoreo-api/api/handlers/webhook_handler.go selected a webhook provider from caller-controlled X-Event-Key, accepted Bitbucket requests without HMAC-SHA256 in X-Hub-Signature or a configured bitbucket-secret, and allowed unauthenticated build triggers for components matched by repository URL and branch, including cross-provider triggers using attacker-supplied commit SHAs. This issue is fixed in versions 1.0.3, 1.1.3, and 1.2.0-rc.2.","publishedAt":"2026-08-13T22:17:28","lastModifiedAt":"2026-08-14T17:20:36","sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-73840","cvssScore":5.3,"cvssVector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L","epssProbability":0.00237,"riskScore":0.54,"affectedProduct":"OpenChoreo","affectedVersions":"<1.0.3, <1.1.3, <1.2.0rc2","vulnerabilityType":"Web app","operatingSystems":[],"links":{"self":"https://www.redsauce.net/api/cves/CVE-2026-73840","webPages":{"es":"https://www.redsauce.net/es/cves/CVE-2026-73840","en":"https://www.redsauce.net/en/cves/CVE-2026-73840","fr":"https://www.redsauce.net/fr/cves/CVE-2026-73840","pt":"https://www.redsauce.net/pt/cves/CVE-2026-73840","de":"https://www.redsauce.net/de/cves/CVE-2026-73840","sk":"https://www.redsauce.net/sk/cves/CVE-2026-73840","el":"https://www.redsauce.net/el/cves/CVE-2026-73840"},"source":"https://nvd.nist.gov/vuln/detail/CVE-2026-73840"}}
