Summary

PraisonAI versions before 4.6.78 default the prompt injection defense block threshold to CRITICAL severity, so HIGH-level threats pass through unblocked. Attackers can submit single-vector prompt injections, such as instruction overrides or financial manipulation, that are detected at HIGH severity and logged without being blocked, enabling system prompt extraction and unauthorized tool invocations. VulnCheck rates the issue CVSS 4.0 8.7 HIGH, and NVD has not yet provided an assessment.
