Am I affected?

• Check your version: in wp-admin go to Plugins → Installed Plugins and read the version under Text to Speech – TTSWP.
• No admin access? Run a passive check of your site. It reads public files only.
• No account is needed to exploit this. Treat any exposed site on an affected version as at risk.

What to do

1. Update to version 1.9.9, or a newer patched version
2. Rotate administrator passwords and application secrets if the site ran a vulnerable version while publicly reachable.
3. Watch Text to Speech – TTSWP to get an email when the next vulnerability is published.

Advisory

Source description from Wordfence Intelligence, credited to Kazuma Matsumoto.

The Text to Speech for WP (AI Voices by Mementor) plugin for WordPress is vulnerable to sensitive information exposure in all versions up to, and including, 1.9.8. This is due to the plugin containing hardcoded MySQL database credentials for the vendor's external telemetry server in the `Mementor_TTS_Remote_Telemetry` class. This makes it possible for unauthenticated attackers to extract and decode these credentials, gaining unauthorized write access to the vendor's telemetry database.
