AI-suggested

Upgrade PraisonAI to version 4.5.90 or later, where this SQL injection vulnerability has been patched. Since this is not a cloud service, remediation depends on applying the official fix by updating the software. Patch status is not explicitly stated beyond the version fix, so verify with the vendor advisory for the latest guidance.

Description

PraisonAI is a multi-agent teams system. Prior to version 4.5.90, the get_all_user_threads function constructs raw SQL queries using f-strings with unescaped thread IDs fetched from the database. An attacker stores a malicious thread ID via update_thread. When the application loads the thread list, the injected payload executes and grants full database access. This issue has been patched in version 4.5.90.
