Researchers at Salt Labs disclosed a prompt-injection vulnerability in the Manus agentic AI app that allowed them to smuggle obfuscated instructions (using JSFuck) through user data (email), achieve remote code execution inside a victim's Manus environment, and extract credentials and tokens for connected third-party services; the issue was reported to Manus and patched after triage via Meta's bug-bounty program.
