LLM01:2025: Prompt Injection
Direct or indirect manipulation of the LLM via crafted prompts to bypass instructions, exfiltrate data, or misuse tools. Indirect injection uses retrieved/loaded content (websites, docs, emails) as the injection vector.
How it's found
Identified by submitting adversarial prompt suites, including indirect injection via retrieved content, to test resistance to instruction override.
Vulnerable vs. safe
