{"id":"CVE-2026-42339","summary":"New API: SSRF Filter Bypass via 0.0.0.0","details":"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.","aliases":["GHSA-v5c3-6wvc-pc2q","GO-2026-5652"],"modified":"2026-08-12T03:30:19.449040820Z","published":"2026-05-08T22:21:53.902Z","related":["openSUSE-SU-2026:21483-1"],"database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/42xxx/CVE-2026-42339.json","cna_assigner":"GitHub_M","cwe_ids":["CWE-918"]},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/42xxx/CVE-2026-42339.json"},{"type":"ADVISORY","url":"https://github.com/QuantumNous/new-api/security/advisories/GHSA-v5c3-6wvc-pc2q"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-42339"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/quantumnous/new-api","events":[{"introduced":"0"},{"fixed":"5238f279db8b096d2b50854633cc2b59d1ba4225"}],"database_specific":{"cpe":"cpe:2.3:a:newapi:new_api:*:*:*:*:*:*:*:*","extracted_events":[{"introduced":"0"},{"last_affected":"0.11.9-alpha.1"},{"fixed":"0.11.9"}],"source":["AFFECTED_FIELD","CPE_RANGE"]}}],"versions":["v0.11.9-alpha.2","v0.11.9-alpha.3","v0.11.9-alpha.1","v0.11.8","v0.11.7","v0.11.6-patch.1","v0.11.6","v0.11.5","v0.11.4-patch.1"],"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2026-42339.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V4","score":"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"}]}
