CVE-2026-80050

Impact

ContiNew Admin fails to apply file-upload permission checks or file-type allowlist validation to multipart upload endpoints, allowing authenticated users to store files with arbitrary extensions. Attackers can initialize chunked uploads, send file parts, and complete uploads to leave arbitrary files in the storage backend accessible via web server URLs.
