Hiding in Plain Floats: Steganographic Carriers for Indirect Prompt and Content Injection

Text-centered prompt-injection defenses assume that the malicious signal is visible in one of the inspected text views. We study a reproducible LLM01-style indirect prompt/content-injection failure mode where that assumption breaks: a payload caught in plain English slips past the same detector...

Google Chrome 80 JSCreate Side-Effect Type Confusion Exploit

This Metasploit module exploits an issue in Google Chrome version 80.0.3987.87 64 bit. The exploit corrupts the length of a float array floatrel, which can then be used for out of bounds read and write on adjacent memory. The relative read and write is then used to modify a UInt64Array uint64aarw...
