NewCVE-2026-30967 (opens in a new tab)How to fix?
Upgrade parse-server to version 8.6.22, 9.5.2-alpha.9 or higher.
Overview
parse-server is a version of the Parse backend that can be deployed to any infrastructure that can run Node.js.
Affected versions of this package are vulnerable to Insufficiently Protected Credentials in the OAuth2 authentication process when the useridField option is not set. An attacker can gain unauthorized access to other user accounts by authenticating with any valid OAuth2 token from the same provider.
Note: This is only exploitable if the generic OAuth2 authentication adapter is enabled with oauth2: true and the useridField option is not configured.
Workaround
This vulnerability can be mitigated by setting the useridField option to the appropriate field name (e.g., sub) in the authentication configuration.
