{"cve":"CVE-2026-42339","nvd":{"published":"2026-05-08T23:16:36.917","modified":"2026-07-24T21:10:00.143","status":"Analyzed","description":"New API is a large language mode (LLM) gateway and artificial intelligence (AI) asset management system. In versions 0.11.9-alpha.1 and prior, the SSRF protection introduced in v0.9.0.5 (CVE-2025-59146) and hardened in v0.9.6 (CVE-2025-62155) does not block the unspecified address 0.0.0.0. A regular (non-admin) user holding any valid API token can send a multimodal request to /v1/chat/completions, /v1/responses, or /v1/messages with 0.0.0.0 as the image/file URL host, bypassing the private-IP filter and causing the server to issue HTTP requests to localhost. This constitutes at minimum a blind SSRF; when the request is routed through an AWS/Bedrock Claude adaptor, the fetched content is inlined into the model response, upgrading it to a full-read SSRF. At time of publication, there are no publicly available patches.","cvss_v4":{"vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:L/VI:H/VA:N/SC:N/SI:N/SA:N","score":7.1},"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:H/A:N","score":7.1},"cwes":["CWE-918"],"references":["https://github.com/QuantumNous/new-api/security/advisories/GHSA-v5c3-6wvc-pc2q","https://github.com/QuantumNous/new-api/security/advisories/GHSA-v5c3-6wvc-pc2q"],"products":["newapi:new_api"],"source":"nvd","synced_at":"2026-10-19T22:33:55.586217763+00:00"},"epss":{"cve":"CVE-2026-42339","score":0.00258,"percentile":0.17511,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-v5c3-6wvc-pc2q","url":"https://osv.dev/vulnerability/GHSA-v5c3-6wvc-pc2q","summary":"QuantumNous/new-api has an SSRF Filter Bypass via 0.0.0.0","modified":"2026-06-25T23:11:44.391759834Z","packages":[{"ecosystem":"Go","name":"github.com/QuantumNous/new-api","purl":"pkg:golang/github.com/QuantumNous/new-api","ranges":["<=0.11.9-alpha.1"],"fixed":[]}]},{"id":"GO-2026-5652","url":"https://osv.dev/vulnerability/GO-2026-5652","summary":"QuantumNous/new-api has an SSRF Filter Bypass via 0.0.0.0 in github.com/QuantumNous/new-api","modified":"2026-06-25T23:01:38.526284588Z","packages":[{"ecosystem":"Go","name":"github.com/QuantumNous/new-api","purl":"pkg:golang/github.com/QuantumNous/new-api","ranges":["all versions"],"fixed":[]}]}],"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).
