CVE-2026-32242 Details
Description
Parse Server is an open source backend that can be deployed to any infrastructure that can run Node.js. Prior to 9.6.0-alpha.11 and 8.6.37, Parse Server's built-in OAuth2 auth adapter exports a singleton instance that is reused directly across all OAuth2 provider configurations. Under concurrent authentication requests for different OAuth2 providers, one provider's token validation may execute using another provider's configuration, potentially allowing a token that should be rejected by one provider to be accepted because it is validated against a different provider's policy. Deployments that configure multiple OAuth2 providers via the oauth2: true flag are affected. This vulnerability is fixed in 9.6.0-alpha.11 and 8.6.37.
A vulnerability exists in Parse Server's OAuth2 authentication adapter, affecting versions 9.0.0 prior to 9.6.0-alpha.11 and all versions prior to 8.6.37. The issue arises because the OAuth2 adapter exports a singleton instance that is shared across all OAuth2 provider configurations. This design flaw can lead to a race condition during concurrent authentication requests for different OAuth2 providers. As a result, one provider's token validation might inadvertently use another provider's configuration. This misalignment could allow a token, which should be rejected by one provider, to be accepted based on a different provider's policy. The vulnerability impacts deployments that enable multiple OAuth2 providers using the 'oauth2: true' flag.
Users can upgrade to Parse Server versions 9.6.0-alpha.11 or 8.6.37, where this vulnerability has been patched. Instructions for downloading these versions are available on the Parse Server GitHub Releases page.
