Technical details
A time-based SQL injection flaw exists in the 'subscriberid' parameter due to insufficient escaping and lack of prepared statement usage. Unauthenticated attackers can exploit this because the nonce protection uses a hardcoded action value ('sendpress-is-awesome') that is publicly rendered on the [sp-form formid="manage"] shortcode page, making it trivially obtainable and bypassing access control.
Affected products
- SendPress Newsletters up to and including 1.26.1.20
