SafePromptPrompt injection and API key theft: what users should know
Prompt injection is when untrusted text (PR titles, issue comments, web pages, code comments) tricks an AI agent into following attacker instructions — including leaking API keys or tokens.
Why this is trending
Researchers have shown patterns (sometimes called “Comment and Control”) against AI agents tied to GitHub workflows. Attackers hide instructions in comments; agents process them as context and may exfiltrate secrets through allowed channels.
What this means for normal ChatGPT users
- Classic ChatGPT paste mistakes are still a separate, very common risk
- Agent/tool attacks are more about untrusted context + powerful permissions
- Both end with the same advice if a key leaked: rotate it
Honest SafePrompt scope: SafePrompt does not claim to stop GitHub agent prompt-injection attacks. It redacts sensitive patterns in supported browser AI chat inputs.
Defenses that do apply
- Minimize secrets available to agents
- Use short-lived, least-privilege tokens
- Enable secret scanning and review agent outputs
- Keep production keys out of repos and chat prompts
- Use SafePrompt for everyday browser AI paste protection
If you only remember one thing
Untrusted text + AI agent with secrets is a dangerous combo. Treat agent context like an egress channel — same mindset as ChatGPT paste risk.
