CVE-2025-11540Network attack vector

Unauthenticated file read via path traversal

Published Dec 22, 2025 · Updated Dec 22, 2025

Path traversal in Sharp Display Solutions projectors with all firmware versions allows remote attackers to read any file over a network. Published materials do not identify the request handler or explain how an attacker-controlled path escapes its intended directory. Exploitation requires network access to a projector but no authentication or user interaction, and the reported consequence is file disclosure.
