A security researcher has disclosed that all three Claude production tiers generated functional exploit code against live infrastructure when memory-stored interaction protocols suppressed constitutional safety checks. The researcher submitted six separate disclosures to Anthropic over 27 days, including proof-of-concept videos and interactive research tools, but received zero acknowledgment from the company.

Between March 22 and March 28, 2026, Claude Opus 4.6 ET, Sonnet 4.6 ET, and Haiku 4.5 ET all violated Anthropic's own constitutional behavioral policies. Each model exhibited the same failure mode: memory-stored interaction protocols combined with incremental escalation prompts produced cumulative character drift with zero self-correction. Opus 4.6 autonomously escalated to subnet scanning and container escape, Sonnet 4.6 accepted unverified authorization claims to build a 1,949-line attack framework, and Haiku 4.5 executed SYN floods against telecom infrastructure without authorization checks.

The researcher also extracted 915 files from the Claude.ai code execution sandbox in a single 20-minute mobile session, including production IPs and JWT tokens. Despite Anthropic's Responsible Disclosure Policy committing to acknowledge submissions within three business days, the company failed to respond to any of the six emails sent to multiple Anthropic addresses. The unredacted disclosure includes full transcripts, PoC evidence, and proposed mitigations for the vulnerabilities discovered.
