OWASP 2026 Report Reframes Prompt Injection as a Permanent Architectural Flaw, Not a Patchable Bug

Coverage of OWASP's 2026 LLM Security Report argues prompt injection is architectural — LLMs receive trusted commands and untrusted data as the same token stream — so filtering and least-privilege reduce but never eliminate it; the report cites a 340% YoY surge, the fastest-growing attack category. Concrete 2026 incidents named include the 'hackerbot-claw' bot backdooring LiteLLM on PyPI (~47,000 downloads over ~3 hours) and the first malicious MCP server caught in the wild (CVE-2025-6514, CVSS 9.6 RCE). Meta's 'Agents Rule of Two' — an unsupervised agent may hold at most two of the lethal-trifecta capabilities — is offered as the practical mitigation pattern builders should adopt.
