Server path disclosure via unsanitized API errors
Published Aug 18, 2025 · Updated Aug 18, 2025
Information disclosure in NamelessMC before 2.2.4 allows remote attackers to obtain server filesystem paths through the member-list API. An empty list parameter makes MemberListManager throw an exception, and ErrorHandler returns the file path, line number, and stack trace in plaintext. No authentication or user interaction is required; the disclosed paths expose deployment layout but not file contents.
