CVE-2026-35200

Parse Server is an open source backend that can be deployed to any infrastructure that can run Node.js. Prior to 8.6.73 and 9.7.1-alpha.4, a file can be uploaded with a filename extension that passes the file extension allowlist e.g., .txt but with a Content-Type header that differs from the...

CVE-2026-35200

Parse Server has a Content-Type mismatch vulnerability in file uploads: if a filename extension passes the allowlist but the Content-Type header differs (e.g., .txt with text/html), the Content-Type is forwarded to storage adapters (such as S3 or GCS) and served as-is. Affected versions are prior...
