Parse Server vulnerable to Prototype Pollution via Cloud Code Webhooks or Cloud Code Triggers
Impact
Keywords that are specified in the Parse Server option requestKeywordDenylist can be injected via Cloud Code Webhooks or Triggers. This will result in the keyword being saved to the database, bypassing the requestKeywordDenylist option.
Patches
Improved keyword detection.
Workarounds
Configure your firewall to only allow trusted servers to make request to the Parse Server Cloud Code Webhooks API, or block the API completely if you are not using the feature.
