AI Agent Vulnerabilities Enable Hijacking in Perplexity Comet Browser

Summary

Zenity Labs discovered the PleaseFix vulnerability family in Perplexity Comet, which allows attackers to hijack AI agents via indirect prompt injection to exfiltrate local files and take over 1Password accounts.

Take Action:
