Summary
Parse Server: Stored XSS via non-standard file extension bypassing file upload extension blocklist
Details

Parse Server is an open source backend that can be deployed to any infrastructure that can run Node.js. Prior to 9.9.1 and 8.6.81, the default fileUpload.fileExtensions blocklist could be bypassed by uploading a file with a non-standard or compound extension and dangerous content type, allowing storage adapters such as S3 and GCS to serve attacker-supplied active content and enable stored cross-site scripting. This issue is fixed in versions 9.9.1 and 8.6.81.
