 "title": "Better Messages <= 3.0.14 - Authenticated (Subscriber+) Sensitive Information Exposure via 'reply_to' Message Meta in AI Chat Bot Conversations",
 "description": "The Better Messages plugin for WordPress is vulnerable to Sensitive Information Exposure via the 'reply_to' message meta in all versions up to, and including, 3.0.14. This is due to the plugin not checking that a replied-to message belongs to the same conversation, while the AI chat bot reply context loads the replied-to message by ID and adds its text and attachments to the bot prompt. This makes it possible for authenticated attackers with Subscriber-level access or above who can message an AI chat bot to get the bot to reveal the content of messages from conversations they do not belong to.",
