Description
### Impact The GraphQL API endpoint does not respect the `allowOrigin` server option and unconditionally allows cross-origin requests from any website. This bypasses origin restrictions that operators configure to control which websites can interact with the Parse Server API. The REST API correctly enforces the configured `allowOrigin` restriction. ### Patches The GraphQL API endpoint now uses the same CORS middleware as the REST API, ensuring the `allowOrigin` and `allowHeaders` server options are consistently enforced across all endpoints. ### Workarounds There is no known workaround other than upgrading. ### Resources - GitHub security advisory: https://github.com/parse-community/parse-server/security/advisories/GHSA-q3p6-g7c4-829c - Fix Parse Server 9: https://github.com/parse-community/parse-server/pull/10334 - Fix Parse Server 8: https://github.com/parse-community/parse-server/pull/10335
