Tenuo authorization primitive reduces OWASP Finbot attack success to zero

According to GitHub documentation, Tenuo, an open protocol with open-source implementation, when integrated into OWASP FinBot CTF, reduced attack success from 50 successful attacks to zero. Tenuo operates by issuing task-scoped warrants—signed lists of permitted tools and argument values—built from database records rather than prompts, and validates every tool call against this warrant before execution.
