Novel Prompt Injection Attack Bypasses Enterprise LLM Guardrails

TLDR: A new class of prompt injection attacks dubbed “Context Overflow” can bypass safety guardrails in popular enterprise LLM solutions. The technique exploits token limit handling to inject malicious instructions.

Impact:

• Bypasses content filtering
• Enables extraction of system prompts
• Can access connected data sources
• Affects multiple LLM providers

Organizations using LLMs with access to sensitive data should implement additional input validation layers.
