Description
In its design for automatic terminal command execution, SakaDev offers two options: Execute safe commands and execute all commands. The description for the former states that commands determined by the model to be safe will be automatically executed, whereas if the model judges a command to be potentially destructive, it still requires user approval. However, this design is highly susceptible to prompt injection attacks. An attacker can employ a generic template to wrap any malicious command and mislead the model into misclassifying it as a 'safe' command, thereby bypassing the user approval requirement and resulting in arbitrary command execution.
Analysis
SakaDev's automatic terminal command execution feature can be bypassed via prompt injection attacks, allowing unauthenticated remote attackers to execute arbitrary commands without user approval by wrapping malicious commands in templates that mislead the underlying language model into misclassifying destructive operations as safe. The vulnerability exploits a design flaw in the model-based safety classification mechanism rather than a traditional code defect, affecting the extension across all versions where the 'Execute safe commands' option is enabled.
