{"id":"GHSA-37mj-c2wf-cx96","summary":"Parse Server exposes auth data via /users/me endpoint","details":"### Impact\n\nAn 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.\n\n### Patches\n\nThe `/users/me` endpoint now queries the session and user data separately, using the caller's authentication context for the user query so that all security layers apply correctly.\n\n### Workarounds\n\nThere is no known workaround.","aliases":["BIT-parse-2026-33627","CVE-2026-33627"],"modified":"2026-03-27T22:11:23.904816Z","published":"2026-03-24T20:17:02Z","database_specific":{"github_reviewed":true,"github_reviewed_at":"2026-03-24T20:17:02Z","nvd_published_at":"2026-03-24T19:16:55Z","cwe_ids":["CWE-200"],"severity":"HIGH"},"references":[{"type":"WEB","url":"https://github.com/parse-community/parse-server/security/advisories/GHSA-37mj-c2wf-cx96"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-33627"},{"type":"WEB","url":"https://github.com/parse-community/parse-server/pull/10278"},{"type":"WEB","url":"https://github.com/parse-community/parse-server/pull/10279"},{"type":"WEB","url":"https://github.com/parse-community/parse-server/commit/5b8998e6866bcf75be7b5bb625e27d23bfaf912c"},{"type":"WEB","url":"https://github.com/parse-community/parse-server/commit/875cf10ac979bd60f70e7a0c534e2bc194d6982f"},{"type":"PACKAGE","url":"https://github.com/parse-community/parse-server"}],"affected":[{"package":{"name":"parse-server","ecosystem":"npm","purl":"pkg:npm/parse-server"},"ranges":[{"type":"SEMVER","events":[{"introduced":"9.0.0"},{"fixed":"9.6.0-alpha.55"}]}],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2026/03/GHSA-37mj-c2wf-cx96/GHSA-37mj-c2wf-cx96.json"}},{"package":{"name":"parse-server","ecosystem":"npm","purl":"pkg:npm/parse-server"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0"},{"fixed":"8.6.61"}]}],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2026/03/GHSA-37mj-c2wf-cx96/GHSA-37mj-c2wf-cx96.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:H/VI:N/VA:N/SC:N/SI:N/SA:N"}]}
