Technical details

The vulnerability is a stored cross-site scripting (XSS) flaw in the avatar field handling of the wppb_save_avatar_value() function. Insufficient input sanitization allows unauthenticated attackers to inject arbitrary JavaScript by uploading a zero-length multipart file, bypassing validation checks and writing directly to user metadata. The payload is later rendered unescaped by wppb_default_fields_make_upload_button() when an administrator accesses the user profile.
