50 CVEs in 18 months is not a growing pain. It's a design choice the industry keeps making.
MCP went from unknown to default AI integration in under two years. The vulnerability count, the OWASP Top 10, and the simultaneous client failures tell a story about what happens when adoption is the only metric.

Spirit Airlines is dead. Its attack surface isn't.
The security story isn't that an airline went bankrupt. It's what happens to 132 APIs, years of customer PII, and a cloud footprint when a company dies overnight and nobody is left to decommission it.

The most dangerous sentence in a code comment is 'this should never happen'
From Therac-25 to CrowdStrike, the same pattern keeps producing catastrophic failures: an engineer reasons that a condition is impossible, skips the guard, and the system outgrows the assumption.

A 4.3 that mattered: the 13-day gap between patch and exploitation flag
Microsoft patched CVE-2026-32202 on April 14 without marking it exploited. APT28 had been using it since at least December. The gap between those two facts is where triage models break.

The same LDAP injection, in two firewalls, in the same month
OPNsense shipped a textbook LDAP filter injection that hid for eleven years. WatchGuard disclosed the same class of flaw weeks later. The pattern is not coincidence.

The Vercel breach is the Heroku/Travis CI playbook, rerun through an AI tool
A compromised OAuth token at a small AI productivity company gave attackers a path into Vercel's internal systems. The structural pattern is four years old. AI tools are making it worse.

CVE-2026-41940 isn't just a cPanel bug. It's a design assumption that shipped for a decade.
A CRLF injection in cPanel's session writer gave attackers unauthenticated root in four requests. The fix landed. The architecture question hasn't. Updated May 4 with exploitation scale: 44,000+ hosts compromised, ransomware, botnet, and state-sponsored campaigns confirmed.
