{"url":"http://public2.vulnerablecode.io/api/vulnerabilities/74813?format=json","vulnerability_id":"VCID-yudk-1urq-a3hj","summary":"Nhost is an open source Firebase alternative with GraphQL. 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.","aliases":[{"alias":"CVE-2026-34969"},{"alias":"GHSA-g2qj-prgh-4g9r"}],"fixed_packages":[],"affected_packages":[],"references":[{"reference_url":"https://api.first.org/data/v1/epss?cve=CVE-2026-34969","reference_id":"","reference_type":"","scores":[{"value":"0.00063","scoring_system":"epss","scoring_elements":"0.20026","published_at":"2026-06-12T12:55:00Z"},{"value":"0.00063","scoring_system":"epss","scoring_elements":"0.19853","published_at":"2026-06-11T12:55:00Z"}],"url":"https://api.first.org/data/v1/epss?cve=CVE-2026-34969"},{"reference_url":"https://docs.nhost.io/products/auth/pkce","reference_id":"","reference_type":"","scores":[{"value":"7.5","scoring_system":"cvssv3.1","scoring_elements":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N"},{"value":"2.3","scoring_system":"cvssv4","scoring_elements":"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"},{"value":"LOW","scoring_system":"generic_textual","scoring_elements":""}],"url":"https://docs.nhost.io/products/auth/pkce"},{"reference_url":"https://github.com/nhost/nhost","reference_id":"","reference_type":"","scores":[{"value":"7.5","scoring_system":"cvssv3.1","scoring_elements":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N"},{"value":"2.3","scoring_system":"cvssv4","scoring_elements":"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"},{"value":"LOW","scoring_system":"generic_textual","scoring_elements":""}],"url":"https://github.com/nhost/nhost"},{"reference_url":"https://nvd.nist.gov/vuln/detail/CVE-2026-34969","reference_id":"","reference_type":"","scores":[{"value":"7.5","scoring_system":"cvssv3.1","scoring_elements":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N"},{"value":"2.3","scoring_system":"cvssv4","scoring_elements":"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"},{"value":"LOW","scoring_system":"generic_textual","scoring_elements":""}],"url":"https://nvd.nist.gov/vuln/detail/CVE-2026-34969"},{"reference_url":"https://github.com/nhost/nhost/security/advisories/GHSA-g2qj-prgh-4g9r","reference_id":"GHSA-g2qj-prgh-4g9r","reference_type":"","scores":[{"value":"7.5","scoring_system":"cvssv3.1","scoring_elements":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N"},{"value":"2.3","scoring_system":"cvssv4","scoring_elements":"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"},{"value":"LOW","scoring_system":"generic_textual","scoring_elements":""},{"value":"Track","scoring_system":"ssvc","scoring_elements":"SSVCv2/E:P/A:N/T:P/P:M/B:A/M:M/D:T/2026-04-07T15:47:19Z/"}],"url":"https://github.com/nhost/nhost/security/advisories/GHSA-g2qj-prgh-4g9r"}],"weaknesses":[{"cwe_id":200,"name":"Exposure of Sensitive Information to an Unauthorized Actor","description":"The product exposes sensitive information to an actor that is not explicitly authorized to have access to that information."},{"cwe_id":598,"name":"Use of GET Request Method With Sensitive Query Strings","description":"The web application uses the HTTP GET method to process a request and includes sensitive information in the query string of that request."}],"exploits":[],"severity_range_score":"0.1 - 7.5","exploitability":null,"weighted_severity":null,"risk_score":null,"resource_url":"http://public2.vulnerablecode.io/vulnerabilities/VCID-yudk-1urq-a3hj"}
