CVE-2026-39381: CWE-863: Incorrect Authorization in parse-community parse-server
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.
AI Analysis
Technical Summary
Parse Server versions >= 9.0.0 and < 9.8.0-alpha.7, as well as versions >= 7.0.0 and < 8.6.75, contain an incorrect authorization vulnerability (CWE-863) in the GET /sessions/me endpoint. This endpoint returns _Session fields configured as protected via the protectedFields server option, allowing any authenticated user to retrieve their own session's protected fields. The GET /sessions and GET /sessions/:objectId endpoints do not exhibit this behavior and correctly strip protected fields. The vulnerability is addressed in parse-server versions 9.8.0-alpha.7 and 8.6.75.
Potential Impact
Authenticated users can access protected session fields that should be restricted, potentially exposing sensitive session information. The vulnerability does not allow access to other users' sessions or escalate privileges beyond the authenticated user's own session data. The CVSS 4.0 base score is 5.3, indicating a medium severity impact.
Mitigation Recommendations
Upgrade parse-server to version 9.8.0-alpha.7 or later, or 8.6.75 or later, where this vulnerability is fixed. There is no official remediation level stated beyond the fix in these versions. Patch status is confirmed by the version fix information. No additional mitigation is indicated.
