Technical details

A second-order SQL injection vulnerability exists in PraisonAI's SQLAlchemy data layer. The 'get_all_user_threads' function in 'src/praisonai/praisonai/ui/sql_alchemy.py' constructs raw SQL queries using Python f-strings to include thread IDs previously stored in the database. An attacker can first call 'update_thread' to store a malicious SQL payload as a 'thread_id'. When 'get_all_user_threads' is subsequently called, the unescaped payload is concatenated into an 'IN' clause, allowing for arbitrary SQL execution. This can result in full database exfiltration or modification. The vulnerability is resolved in version 4.5.90 by properly parameterizing queries.
