SQL Injection in parisneo/lollms-webui

An SQL injection vulnerability exists in the delete_discussion() function of the parisneo/lollms-webui application, allowing an attacker to delete all discussions and message data. The vulnerability is exploitable via a crafted HTTP POST request to the /delete_discussion endpoint, which internally calls the vulnerable delete_discussion() function. By sending a specially crafted payload in the 'id' parameter, an attacker can manipulate SQL queries to delete all records from the 'discussion' and 'message' tables. This issue is due to improper neutralization of special elements used in an SQL command.
