Summary

A vulnerability in PraisonAI before version 4.6.78 stems from a misconfigured prompt injection defense where the default block threshold is set to CRITICAL severity. This allows HIGH-severity attacks to pass through unblocked, enabling system prompt extraction and unauthorized tool invocations.

Risk Assessment

The organization is at risk of system prompt theft and unauthorized tool operations by an attacker, potentially leading to sensitive data leakage or financial manipulation.

Recommendation

Immediately update PraisonAI to version 4.6.78 or later and configure the block threshold to HIGH or lower to prevent prompt injection attacks.

Original NVD description (English source)

PraisonAI versions before 4.6.78 contain a prompt injection defense misconfiguration where the block threshold defaults to CRITICAL severity, allowing HIGH-level threats to pass through unblocked. Attackers can submit single-vector prompt injection attacks such as instruction overrides or financial manipulation that trigger HIGH severity detection but are logged without blocking, enabling system prompt extraction and unauthorized tool invocations.
