Security Findings2

Severity	Finding	Layer	Location
CRITICAL	Unsanitized user input in bash command construction The SKILL.md instructs the agent to construct `bash` commands by directly embedding user-provided input (e.g., passwords, backup IDs) without proper sanitization or escaping. Since the skill declares `bash` as an allowed tool, a malicious user can inject arbitrary shell commands by providing specially crafted input containing shell metacharacters. This allows for remote code execution, data exfiltration, or system compromise. The agent must sanitize or properly escape all user-provided input before embedding it into `bash` command strings. For example, by quoting arguments or using a shell-escaping utility. This applies to all commands where user input is directly inserted into a shell command, such as `backup`, `restore`, and `diff`.	LLM	SKILL.md:79
HIGH	Dangerous tool allowed: bash The skill allows the 'bash' tool without constraints. This grants arbitrary command execution. Remove unconstrained shell/exec tools from allowed-tools, or add specific command constraints.	Static	skills/ibitnoah/unibase-membase/SKILL.md:1
