CVE-2024-47183: Parse Server's custom object ID allows to acquire role privileges
First published: Fri Oct 04 2024(Updated: )
### Impact If the Parse Server option `allowCustomObjectId: true` is set, an attacker that is allowed to create a new user can set a custom object ID for that new user that exploits the vulnerability and acquires privileges of a specific role. ### Patches Improved validation for custom user object IDs. Session tokens for existing users with an object ID that exploits the vulnerability are now rejected. ### Workarounds - Disable custom object IDs by setting `allowCustomObjectId: false` or not setting the option which defaults to `false`. - Use a Cloud Code Trigger to validate that a new user's object ID doesn't start with the prefix `role:`. ### References - https://github.com/parse-community/parse-server/security/advisories/GHSA-8xq9-g7ch-35hg - https://github.com/parse-community/parse-server/pull/9317 (fix for Parse Server 7) - https://github.com/parse-community/parse-server/pull/9318 (fix for Parse Server 6)
