{"cve":"CVE-2026-33627","nvd":{"published":"2026-03-24T19:16:55.190","modified":"2026-06-17T10:37:48.607","status":"Analyzed","description":"Parse Server is an open source backend that can be deployed to any infrastructure that can run Node.js. Prior to versions 8.6.61 and 9.6.0-alpha.55, an authenticated user calling GET /users/me receives unsanitized auth data, including sensitive credentials such as MFA TOTP secrets and recovery codes. The endpoint internally uses master-level authentication for the session query, and the master context leaks through to the user data, bypassing auth adapter sanitization. An attacker who obtains a user's session token can extract MFA secrets to generate valid TOTP codes indefinitely. This issue has been patched in versions 8.6.61 and 9.6.0-alpha.55.","cvss_v4":{"vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:H/VI:N/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:H/I:N/A:N","score":6.5},"cwes":["CWE-200"],"references":["https://github.com/parse-community/parse-server/commit/5b8998e6866bcf75be7b5bb625e27d23bfaf912c","https://github.com/parse-community/parse-server/commit/875cf10ac979bd60f70e7a0c534e2bc194d6982f","https://github.com/parse-community/parse-server/pull/10278","https://github.com/parse-community/parse-server/pull/10279","https://github.com/parse-community/parse-server/security/advisories/GHSA-37mj-c2wf-cx96"],"products":["parseplatform:parse-server"],"source":"nvd","synced_at":"2026-10-19T22:26:19.218427112+00:00"},"epss":{"cve":"CVE-2026-33627","score":0.00393,"percentile":0.33431,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-37mj-c2wf-cx96","url":"https://osv.dev/vulnerability/GHSA-37mj-c2wf-cx96","summary":"Parse Server exposes auth data via /users/me endpoint","modified":"2026-03-27T22:11:23.904816Z","packages":[{"ecosystem":"npm","name":"parse-server","purl":"pkg:npm/parse-server","ranges":[">=9.0.0 <9.6.0-alpha.55"],"fixed":["9.6.0-alpha.55"]},{"ecosystem":"npm","name":"parse-server","purl":"pkg:npm/parse-server","ranges":["<8.6.61"],"fixed":["8.6.61"]}]}],"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).
