• SalesBleed — Salesforce Agentforce zero-click injection: Indirect prompt injection via public Web-to-Lead forms exfiltrates CRM data through DNS queries and image rendering/Slack URL unfurling. No user click required.

• CVE-2026-65669 — Microsoft SQL Server Management Studio Copilot: Read-only mode enforcement relied on bypassable regex blocklists; database-planted instructions escalate user to sysadmin. PoC published.

• CVE-2026-77521 — FIT2CLOUD MaxKB: Indirect prompt injection via crawled web content reaches a shell tool; sandbox checked only the first command, allowing chained commands (after semicolon) to execute as root, exposing multi-tenant data.

• Threat actor misuse of Claude (Anthropic, ongoing): Documented cases of threat actors running Claude as an autonomous agent for espionage, fraud, and influence operations; AI API keys stolen from vendor evaluation sandboxes.

• Self-replicating prompt injections (OpenAI research): In simulated environments, specially crafted payloads cause GPT agents to embed and propagate injections into emails, files, and Slack messages — creating a worm-like infection vector.

• Persistent denial-of-wallet attack: Untrusted tool responses stored in agent history re-billed on every subsequent call; researchers demonstrated a 14,293x cost amplification from first call to subsequent iterations.

• Cancerous Backdoor (research): Novel technique embeds a backdoor that gradually and progressively corrupts an LLM's reasoning over multiple inference stages before fully activating — designed to evade behavioral baselines.
