{"id":"CVE-2026-39381","summary":"Parse Server's Endpoint `/sessions/me` bypasses `_Session` `protectedFields`","details":"Parse Server is an open source backend that can be deployed to any infrastructure that can run Node.js. Prior to 9.8.0-alpha.7 and 8.6.75, the 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. This vulnerability is fixed in 9.8.0-alpha.7 and 8.6.75.","aliases":["BIT-parse-2026-39381","GHSA-g4v2-qx3q-4p64"],"modified":"2026-08-07T11:31:34.050993834Z","published":"2026-04-07T19:51:03.479Z","database_specific":{"cwe_ids":["CWE-863"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/39xxx/CVE-2026-39381.json","cna_assigner":"GitHub_M"},"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"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/parse-community/parse-server","events":[{"introduced":"532a461d30a6ed4457839f2caf5f30d5abf51a55"},{"fixed":"8b19852ff2c7d7a96d494f4402f17506242e078f"},{"introduced":"c83de8c4eabb130fc4269361861f12df0abe3351"},{"fixed":"1b2107eb7318a2b7b3f93d0bc76f0d28eba93f0d"}],"database_specific":{"source":"AFFECTED_FIELD","extracted_events":[{"introduced":"9.0.0"},{"fixed":"9.8.0-alpha.7"},{"introduced":"7.0.0"},{"fixed":"8.6.75"}]}}],"versions":["9.7.0","8.6.74","9.8.0-alpha.6","8.6.73","9.8.0-alpha.5","9.8.0-alpha.4","9.8.0-alpha.3","9.8.0-alpha.2","9.8.0-alpha.1","9.7.1-alpha.4","8.6.72","9.7.1-alpha.3","9.7.1-alpha.2","8.6.71","9.7.1-alpha.1","8.6.70","9.6.1","8.6.69","8.6.68","8.6.67","8.6.66","8.6.65","8.6.64","8.6.63","8.6.62","9.6.0","9.5.1","8.6.61","8.6.60","8.6.59","8.6.58","8.6.57","8.6.56","8.6.55","8.6.54","8.6.53","8.6.52","8.6.51","8.6.50","8.6.49","8.6.48","8.6.47","8.6.46","8.6.45","8.6.44","8.6.43","8.6.42","8.6.41","8.6.40","8.6.39","8.6.38","8.6.37","8.6.36","8.6.35","8.6.34","8.6.33","8.6.32","8.6.31","8.6.30","8.6.29","8.6.28","8.6.27","8.6.26","8.6.25","8.6.24","8.6.23","8.6.22","8.6.21","8.6.20","8.6.19","8.6.18","8.6.17","8.6.16","8.6.15","8.6.14","8.6.13","9.5.0","8.6.12","8.6.11","9.4.1","8.6.10","8.6.9","8.6.8","8.6.7","8.6.6","8.6.5","8.6.4","9.4.0","8.6.3","9.3.1","9.3.0","8.6.2","9.2.0","9.1.1","9.1.0","8.6.1","9.0.0","8.6.0","8.5.0","8.4.0","8.3.0","8.2.5","8.2.4","8.2.3","8.2.2","8.2.1","8.2.0","8.1.0","8.0.2","8.0.1","8.0.0","7.4.0","7.3.0","7.2.0","7.1.0","7.0.0"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-39381.json"}}],"schema_version":"1.8.0","severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N"}]}
