TL;DR: AI-driven vulnerability discovery is collapsing the time between disclosure and exploitation, with nearly 29% of known exploited vulnerabilities weaponised on or before CVE publication in 2025, according to MindFort's cited VulnCheck research. That shifts web app defence toward continuous testing, dependency triage, and explicit controls for AI agents, MCP servers, and LLM integrations.

By the numbers:
- Nearly 29% of known exploited vulnerabilities in 2025 were weaponized on or before the day their CVE was published.
- Anthropic's frontier red team found over 500 vulnerabilities in production open-source software using Claude Opus 4.6.
- MindFort says its assessments can produce under 1% false positives to triage.
Questions worth separating out
Q: How should security teams test modern web applications continuously?
A: They should combine automated DAST, API scanning, secret detection, and release gating so testing happens in the delivery pipeline rather than as an occasional event.
Q: Why does AI-assisted development complicate application security governance?
A: AI-assisted development complicates governance because the organisation must track who authorised the change, what system generated it, and whether the output can be audited.
Q: What breaks when dependency patching is treated as routine maintenance?
A: Patch backlogs become attack windows when exploitation moves faster than remediation.
Practitioner guidance
- Move to continuous exploit validation Run security testing on every deploy and require proof-of-concept confirmation before findings enter remediation queues.
- Inventory dependencies as live attack surface Track third-party libraries, transitive components, and patch dependencies as part of release governance.
- Treat AI agents and MCP servers as privileged workflows Version, approve, and audit every non-code change an agent can make across tools, data sources, and downstream systems.

AI-assisted exploitation has turned remediation speed into a governance control, not just an engineering metric. Once weaponisation can happen on or before disclosure day, programmes that rely on periodic review are structurally behind. The practical question is no longer whether a vulnerability exists, but whether the organisation can validate and contain it before it is operationalised. For practitioners, this means treating response latency as a security control with measurable ownership.
A question worth separating out:
Q: Who is accountable when an AI agent makes an unauthorised change?
A: Accountability should be assigned to the governance model that authorised the delegation, the owner of the workflow, and the team that set the policy boundary. In practice, organisations need clear responsibility for agent configuration, monitoring, and incident response because the machine’s speed does not remove human accountability for the delegated identity.
