{"id":"CVE-2026-65317","summary":"Verba (goldenverba) Server-Side Request Forgery via /api/connect and Same-Origin Middleware Bypass","details":"Verba RAG application version 2.1.3 contains a server-side request forgery vulnerability combined with a same-origin middleware bypass that allows unauthenticated remote attackers to make the server issue arbitrary HTTP requests by supplying a crafted Origin header and attacker-controlled host and port values. Attackers can bypass the localhost origin check in the API middleware by sending any Origin value prefixed with ' regardless of port, then submit arbitrary host and port parameters to the /api/connect endpoint to cause the server to issue outbound GET requests to attacker-controlled infrastructure.","modified":"2026-07-25T03:56:18.167659371Z","published":"2026-07-21T21:31:01.979Z","database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/65xxx/CVE-2026-65317.json","cna_assigner":"VulnCheck","cwe_ids":["CWE-918"]},"references":[{"type":"WEB","url":"https://github.com/geo-chen/oss/blob/main/verba.md#finding-2-ssrf--same-origin-middleware-bypass-in-apiconnect----goldenverba"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/65xxx/CVE-2026-65317.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-65317"},{"type":"ADVISORY","url":"https://www.vulncheck.com/advisories/verba-goldenverba-server-side-request-forgery-via-api-connect-and-same-origin-middleware-bypass"},{"type":"PACKAGE","url":"https://github.com/weaviate/Verba"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/weaviate/verba","events":[{"introduced":"0"},{"last_affected":"6fb7c98d729bca91efe6be7d835dc9d36a53905f"}],"database_specific":{"source":"AFFECTED_FIELD","extracted_events":[{"introduced":"0"},{"last_affected":"2.1.3"}]}}],"versions":["v2.1.3","v2.1.2","v2.1","v2","v1.0.3","1.0.0","0.4.0","0.3.1","0.3.0","0.2.3"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-65317.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:N/VA:N/SC:H/SI:N/SA:N"}]}
