GHSA-xvh5-5qg4-x9qp: n8n has In-Process Memory Disclosure in its Task Runner

n8n (a workflow automation tool) has a security flaw where authenticated users who can create or modify workflows could access uninitialized memory buffers (chunks of computer memory that haven't been cleared), potentially exposing sensitive data like secrets or tokens from previous requests in the same process. This vulnerability only affects systems where Task Runners are enabled and can be limited in external runner mode (where the runner operates in a separate, isolated process).
