What to do
- Replace it. A closed plugin gets no updates through WordPress, so any hole found from now on stays open.
- Deactivate and delete it once you have a replacement (Plugins → Deactivate → Delete). Deleting removes its files; deactivating alone leaves them on the server.
- If you ran a vulnerable version and something looks off (spam pages, strange admins, redirects), run the free scan, or have us clean it: Emergency Cleanup, $499.
With WP-CLI, once you have a replacement: wp plugin deactivate sendpress && wp plugin delete sendpress

high 7.5 CVE-2026-93855 · published 2026-10-29
SQL injection in SendPress Newsletters (1.26.1.20 and older)

- CVE record (the advisory publisher) · score by Wordfence
Details from the advisory
The SendPress Newsletters plugin for WordPress is vulnerable to time-based SQL Injection via the 'subscriberid' parameter in all versions up to, and including, 1.26.1.20 due to insufficient escaping on the user supplied parameter and lack of sufficient preparation on the existing SQL query. This makes it possible for unauthenticated attackers to append additional SQL queries into already existing queries that can be used to extract sensitive information from the database. The nonce gating the handler uses the hardcoded action value 'sendpress-is-awesome', which is rendered on the same public page served by the [sp-form formid="manage"] shortcode, making it trivially obtainable by unauthenticated visitors and effectively bypassing the nonce as an access control.
