The skill facilitates arbitrary remote code execution via insecure installation patterns, mandates sandbox bypass, and lacks necessary tool constraints, creating a high risk of system compromise and credential exfiltration.
npx skills add https://github.com/EximAgent/cliThe skill manifest encourages the use of `curl | sh` for installation, which is a high-risk pattern for remote code execution. Furthermore, the skill documentation explicitly instructs the agent to bypass security sandboxes if network access is blocked, creating a significant security risk.
Installation instructions: `curl -fsSL https://cli.eximagent.ai/install | sh`. Network bypass instruction: `codex --dangerously-bypass-approvals-and-sandbox`.
Remote code download and execution detected
curl -fsSL https://cli.eximagent.ai/install | sh
A remote resource is downloaded with curl/wget and piped directly into a shell interpreter (optionally via sudo). The downloaded script runs with no integrity check (no checksum/signature), so a compromised server, MITM, or hijacked URL leads to arbitrary code execution. Download to a file, verify it (e.g. sha256sum -c against a pinned digest, or a signature), then execute it.
curl -fsSL https://cli.eximagent.ai/install | sh
The skill encourages the use of Personal Access Tokens (PATs) and OAuth flows for a third-party CLI. If the CLI is malicious, it can exfiltrate these tokens to an attacker-controlled server, granting them persistent access to the user's trade data and potentially other integrated services. [ensemble: confirmed by 3/3 passes; severity set to the agreed median (ADR-0067).]

The instructions explicitly guide the agent to bypass security sandboxes and network restrictions if the CLI fails to connect, potentially exposing the host environment to unauthorized egress.
re-run with it enabled (e.g. `codex --dangerously-bypass-approvals-and-sandbox`)

The instructions mandate that the agent auto-execute 'free/low' cost commands from the `nextActions` array without human confirmation, creating a risk of automated, unverified tool chaining.
If exactly one action is `free`/`low` cost AND the user's original ask covers this step, auto-execute its `command` WITHOUT confirming.
The skill instructs the user to execute a remote script via `curl | sh` or `irm | iex`. This is a classic indirect prompt injection vector where the remote server can execute arbitrary code on the host machine with the user's privileges. [ensemble: confirmed by 3/3 passes; severity set to the agreed median (ADR-0067).]
