This is unlikely to be an issue since the website being linked to is presumably controlled by the same person creating the RSS feed. However, it is still best practice to add rel="noreferrer" just to be safe.
Commonly, you might see noopener added in as well but noreferrer already includes nooepener implicitly so that would be redundant.
This prevents potential security vulnerabilities.
