Information Exposure in Parse Server by Parse Community
CVE-2026-39381
What is CVE-2026-39381?
Parse Server, an open source backend framework, was found to have a vulnerability that allowed authenticated users to access sensitive session information improperly. Specifically, prior to versions 9.8.0-alpha.7 and 8.6.75, the GET /sessions/me endpoint returned protected _Session fields, which should have been restricted based on server configuration. This flaw could potentially expose sensitive data to users in their own session. The GET /sessions and GET /sessions/:objectId endpoints functioned correctly by excluding these protected fields, highlighting a discrepancy in handling session data. The issue has been addressed in subsequent updates, ensuring better security by protecting sensitive information from unauthorized access.
