Prior to 0.48.0, the auth service's OAuth provider callback flow places the refresh token directly into the redirect URL as a query parameter. Refresh tokens in URLs are logged in browser history, server access logs, HTTP Referer headers, and proxy/CDN logs. Note that the refresh token is one-time use and all of these leak vectors are on owned infrastructure or services integrated by the application developer. This vulnerability is fixed in 0.48.0.","state":0,"publishedAt":"2026-04-06T16:01:10.174+00:00","modifiedAt":"2026-04-07T16:00:25.296+00:00","affected":[{"ecosystem":"Vendor product","name":"nhost","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"nhost\",\n                    \"product\": \"nhost\",\n                    \"versions\": [\n                        {\n                            \"version\": \"< 0.48.0\",\n                            \"status\": \"affected\"\n                        }\n                    ]\n                }"}],"metrics":[{"system":"CVSS 4.0","vector":"CVSS:4.0/AV:N/AC:H/AT:P/PR:N/UI:P/VC:N/VI:N/VA:N/SC:L/SI:N/SA:N","score":2.3,"severity":"LOW"}],"references":["https://github.com/nhost/nhost/security/advisories/GHSA-g2qj-prgh-4g9r"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-34969","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-34969","identifiers":["CVE-2026-34969"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
