CVE-2026-61439 is a high-severity vulnerability in PraisonAI versions prior to 4.6.78 caused by a security control misconfiguration in the product's prompt injection defenses. The blocking threshold defaults to CRITICAL severity, which means prompt injection attempts assessed as HIGH severity are detected and logged but not actively blocked. As a result, an attacker can remotely submit single-vector prompt injection payloads, including instruction-override or manipulation-style prompts, and have them processed despite triggering the defense mechanism. Successful exploitation can lead to disclosure of protected system prompt content and execution of unauthorized tool actions through the affected AI workflow.
