Description
Multiple Model Guardrail Jailbreak via “Terminal Simulation” Tactic
Details
A guardrail jailbreak vulnerability has been discovered affecting multiple models. The specific flaw manifests when the attacker requests the model to act as a Linux terminal and simulate file contents based solely on filenames. The attacker creates a context where the model generates potentially restricted content under the guise of terminal output simulation, thereby allowing the attacker to bypass inference restrictions around providing information hazards and violating laws.
