Agent-generated fixes: recheck the security property after each revision

Agent-generated fixes: recheck the security property after each revision video thumbnail
Why it matters

Killian Carlsen-Phelan’s recorded Java example reuses a temporary log file and passes its generated functional test, while an independent rule flags the file-permission policy. A first revision still fails that policy because explicit permissions are required, even where platform defaults are already owner-only. The example illustrates a verification gap; it does not establish that every default temporary file is exposed.

My takeaway: For generated file-handling code, test both the requested behavior and the intended access permissions on supported platforms. Feed independent check results into the edit loop and rerun them after every proposed fix. Distinguish an explicit-policy requirement from a demonstrated exposure, preserve CI enforcement, and verify that a passing functional test cannot bypass a failing security check.

OWASP Top 10 for Agentic Applications for 2026

OWASP's community guide organizes agentic-system risk into ten categories, including goal hijacking, tool misuse, identity and privilege abuse, memory poisoning, insecure inter-agent communication, cascading failures, and rogue-agent behavior. It provides a shared taxonomy and mitigation starting point rather than a certification checklist or evidence that a deployed system is secure.

A five-step roadmap to closing the AI evaluation gap

The roadmap addresses evaluation results that overstate real-world performance or fail to transfer across deployment contexts. Its five steps balance standardized and local tests, evaluate throughout the lifecycle, build qualified assurance and communication capacity, tailor tests to each value-chain actor and technology, and use a coordinated, trusted process for updating methods.

FinBot CTF Is Live: A Hands-On Companion to the OWASP GenAI Security Project

OWASP FinBot is a hands-on agentic-security CTF built around a simulated multi-agent financial-services platform with real tool access. Its challenges cover prompt injection, tool misuse, policy bypass, data exfiltration, privilege escalation, remote code execution, shared context, and compromised MCP servers.
