{"id":"CVE-2026-39381","aliases":["BIT-parse-2026-39381","GHSA-g4v2-qx3q-4p64"],"url":"https://o3.security/vulnerability/CVE-2026-39381","summary":"Parse Server's Endpoint `/sessions/me` bypasses `_Session` `protectedFields`","details":"### Impact\n\nThe `GET /sessions/me` endpoint returns `_Session` fields that the server operator explicitly configured as protected via the `protectedFields` server option. Any authenticated user can retrieve their own session's protected fields with a single request. The equivalent `GET /sessions` and `GET /sessions/:objectId` endpoints correctly strip protected fields.\n\n### Patches\n\nThe `GET /sessions/me` handler now re-fetches the session with the caller's auth context after validating the session token, ensuring `protectedFields` and CLP apply consistently with other session endpoints.\n\n### Workarounds\n\nNone.\n\n### References\n\n- GitHub security advisory: https://github.com/parse-community/parse-server/security/advisories/GHSA-g4v2-qx3q-4p64\n- Fix Parse Server 9: https://github.com/parse-community/parse-server/pull/10406\n- Fix Parse Server 8: https://github.com/parse-community/parse-server/pull/10407","published":"2026-04-07T19:51:03.479Z","modified":"2026-08-12T03:51:18.575237634Z","cvss":null,"epss":null,"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"npm","name":"parse-server","fixedVersion":"9.8.0-alpha.7"},{"ecosystem":"npm","name":"parse-server","fixedVersion":"8.6.75"}],"fix":{"url":"https://github.com/parse-community/parse-server/pull/10406","label":"parse-community/parse-server#10406"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/39xxx/CVE-2026-39381.json"},{"type":"ADVISORY","url":"https://github.com/parse-community/parse-server/security/advisories/GHSA-g4v2-qx3q-4p64"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-39381"},{"type":"FIX","url":"https://github.com/parse-community/parse-server/pull/10406"},{"type":"FIX","url":"https://github.com/parse-community/parse-server/pull/10407"},{"type":"PACKAGE","url":"https://github.com/parse-community/parse-server"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-12T03:51:18.575237634Z"}}
