On September 2, CISA added seven actively exploited vulnerabilities to its Known Exploited Vulnerabilities catalog. Three of them affect remote access infrastructure, orchestration software, and AI-adjacent tooling—the stack that frontier model evaluation environments run on. The additions are not theoretical. They confirm that the infrastructure supporting AI pipelines is already under live attack while the institutions tasked with defending it are still debating whether that infrastructure belongs on their roster at all.
The agency's leadership warned publicly this month that AI is a "gamechanger" threatening to crush critical infrastructure operators under technical debt. CISA is rebuilding after losing roughly one-third of its workforce since January, but its immediate focus is on helping operators prioritize vulnerability backlogs, not on assessing whether the environments where frontier models are tested should be classified as critical infrastructure. The August 2026 Logging Reference Architecture cites Executive Order 14409 and envisions AI and machine learning integrated into security operations, but only within "governed, risk-managed frameworks"—a framing that assumes existing governance can absorb the new capability rather than requiring structural expansion.
This matters because the July evaluation failures produced a consensus prescription: treat frontier model evaluation environments as critical infrastructure, harden them accordingly, and subject them to adversarial human verification rather than automated monitoring. Two months later, no CISA or DHS proposal has emerged to implement that prescription. The absence is not merely bureaucratic delay. It appears to reflect a capacity ceiling: the agency responsible for protecting critical infrastructure is signaling that AI is already exceeding its ability to defend the infrastructure already on its plate.
The tension is between diagnosis and execution. Americans for Responsible Innovation argued in August that AI should be designated as critical infrastructure, with CISA at the center of the protective framework. But CISA's September posture—retiring assessments, shrinking staff, and warning that AI threatens to bury existing defenders—suggests the center cannot hold the framework it has, let alone a larger one. Structural reform may require not just a classification decision but a resource decision that no appropriations process has yet confronted.
If the evaluation environments that failed in July are to be hardened before the next breach, someone must have the staffing, the authority, and the budget to assess them. Right now, the institution with the statutory role lacks the operational capacity, and the institutions with the operational capacity lack the statutory role. The gap is where the next sandbox escape will land.
