Short explanation
The SendPress Newsletters plugin versions up to 1.26.1.20 contain a time‑based, unauthenticated SQL injection in the 'subscriberid' parameter. Attackers can append additional queries to extract sensitive data (S0,S1).
The flaw enables data exfiltration without authentication, exposing confidential information on WordPress sites.
What should be done?
- Apply any vendor‑released patch per the advisory
- If no patch, block the vulnerable endpoint with a WAF
- Sanitize and use prepared statements for all SQL inputs
- Disable or restrict the sp-form shortcode usage
- Monitor server logs for abnormal query timings

Show the technical text from the sources
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.
