What is CVE-2026-56074?

A flaw in PraisonAI prior to version 1.5.128 allows for a bypass of tool approval prompts due to the coarse-grained caching of approval decisions. This vulnerability enables attackers to initially gain approval for a harmless command. However, it allows them to execute subsequent execute_command calls that can exfiltrate sensitive information, such as API keys and credentials, without any user interaction or consent. This poses a significant security risk in environments where command execution is not tightly controlled.
