Medium (5.3) in parseplatform parse-server. EPSS 0.3% chance of exploitation in the next 30 days. Fixed in parse-server 8.6.57, 9.6.0-alpha.48.
Parse Server is an open source backend that can be deployed to any infrastructure that can run Node.js. Prior to versions 8.6.57 and 9.6.0-alpha.48, an authenticated user can overwrite server-generated session fields such as expiresAt and createdWith when updating their own session via the REST API. This allows bypassing the server's configured session lifetime policy, making a session effectively permanent. This issue has been patched in versions 8.6.57 and 9.6.0-alpha.48.
