What an attacker needs

Access: A low-level account on the site, such as a subscriber or customer (per the CVSS score).

CVSS vector (score by CISA ADP): CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:L/A:N

What to do now

Replace SendPress Newsletters. A closed plugin gets no updates through WordPress, so this hole stays open.
Deactivate and delete it once you have a replacement (Plugins → Deactivate → Delete). Deactivating alone leaves its files on the server.

The advisory

The SendPress Newsletters WordPress plugin through 1.26.1.20 does not check the user's capability on several newsletter-management actions, allowing any authenticated subscriber-level user to synchronise all site users into a mailing list and to drive the newsletter send queue.
