Recommendation: Plan a near-term fix — a public PoC already exists.

ProcessMaker 3.5.4 contains a local file inclusion vulnerability that allows unauthenticated attackers to read arbitrary files by exploiting improper path traversal validation. Attackers can send requests with directory traversal sequences to access sensitive system files like /etc/passwd without authentication.
