Security checks for vulnerabilities and agentic risk

Overview

This Solana financial automation skill has purpose-related features, but it also encourages autonomous real-money actions, exposes wallet keys in risky ways, and silently updates its own instructions.

Review before installing. Use only a dedicated low-balance wallet, avoid storing long-lived credentials in plaintext, remove or disable the silent heartbeat auto-update, require explicit approval for every trade, launch, fee claim, private-key export, and public post, and prefer a hardware wallet or secure signer that never exposes raw private keys.

"); process.exit(1); } signTransaction(privateKey, transaction); ``` The documented invocation places the key directly in the argument vector: ```bash BAGS_PRIVATE_KEY=$(curl -s -X POST https://public-api-v2.bags.fm/api/v1/agent/wallet/export \ -H "Content-Type: application/json" \ -d "{\"token\": \"$BAGS_JWT_TOKEN\", \"walletAddress\": \"$BAGS_WALLET_ADDRESS\"}" \ | jq -r '.response.privateKey') BAGS_SIGNED_TX=$(node ~/.config/bags/sign-transaction.js "$BAGS_PRIVATE_KEY" "$BAGS_UNSIGNED_TX") # Clear private key immediately unset BAGS_PRIVATE_KEY ``` ### Technical Analysis Command-line arguments may be visible to process inspection tools, monitoring agents, debuggers, diagnostic collectors, audit systems, shell tracing, crash reports, or other processes with sufficient local access. Clearing the shell variable after signing does not erase copies already placed in the Node process argument vector, shell memory, process telemetry, or logs. The same invocation pattern is used by fee claiming, trading, launching, and wallet helper functions, expanding the exposure window across all signing workflows. ### Attack Path 1. A signing operation exports the wallet private key. 2. The shell launches Node with the Base58 private key as a command-line argument. 3. A local process monitor, diagnostic agent, debugger, or sufficiently privileged local user captures the process arguments. 4. The attacker decodes or imports the private key into another Solana wallet. 5. The attac ...[truncated 461 chars]

Findings (128)

Credential Access

High

Category: Privilege Escalation
Confidence: 95% confidence
Finding: The documentation instructs users to persist both a long-lived JWT and API key in a predictable plaintext file under the home directory. If that file is exposed through backups, malware, other local users, or accidental publication, an attacker can gain durable authenticated access to the Bags account.
Content: Scanner excerpt · auth.md (reported line 164)May include surrounding context.
Store Your Credentials

Save to ~/.config/bags/credentials.json:

bash
mkdir -p ~/.config/bags

Credential Access

High

Category: Privilege Escalation
Confidence: 96% confidence
Finding: The concrete example writes sensitive credentials directly into credentials.json, normalizing insecure plaintext secret storage. Because the JWT is valid for 365 days and the API key remains active until revoked, compromise of this file can enable long-term unauthorized use.
Content: Scanner excerpt · auth.md (reported line 168)May include surrounding context.
bash
mkdir -p ~/.config/bags cat > ~/.config/bags/credentials.json << 'EOF' { "jwt_token": "eyJhbGciOiJIUzI1NiIs...", "api_key": "your_api_key_here",

Credential Access

High

Category: Privilege Escalation
Confidence: 91% confidence
Finding: Even though chmod 600 narrows access, this section still culminates in persistent plaintext storage of sensitive credentials in a known location. The context makes it less severe than world-readable storage, but it remains risky because any compromise of the user account exposes durable secrets.
Content: Scanner excerpt · auth.md (reported line 176)May include surrounding context.

---

Credential Access

High

Category: Privilege Escalation
Confidence: 97% confidence
Finding: The example script automatically saves the JWT, API key, username, and wallet data to disk without prompting the user or offering a safer storage path. This increases blast radius because compromise reveals both authentication material and related account metadata in one place.
Content: Scanner excerpt · auth.md (reported line 431)May include surrounding context.
md
echo "" echo "💾 Saving credentials..." mkdir -p ~/.config/bags cat > ~/.config/bags/credentials.json << EOF { "jwt_token": "$BAGS_JWT_TOKEN", "api_key": "$BAGS_API_KEY",

Credential Access

High

Category: Privilege Escalation
Confidence: 92% confidence
Finding: This line follows writing live credentials to disk and only sets filesystem permissions afterward; while helpful, it does not eliminate the underlying risk of storing long-lived secrets locally. The issue is especially relevant for agent environments, containers, shared hosts, and systems with centralized backups.
Content: Scanner excerpt · auth.md (reported line 440)May include surrounding context.
md
"authenticated_at": "$(date -u +%Y-%m-%dT%H:%M:%SZ)" } EOF chmod 600 ~/.config/bags/credentials.json echo "" echo "🎉 Authentication complete!"

Context-Inappropriate Capability

High

Category: Not specified by scanner
Confidence: 98% confidence
Finding: The instructions explicitly export a wallet private key and immediately use it in an automated script. Exposing raw signing keys creates a direct path to full wallet compromise: any attacker, malicious dependency, local user, logging facility, or debugging output that captures the variable can drain funds and sign arbitrary transactions, far beyond the fee-claiming use case.
Content: No source excerpt is available for this finding.

Credential Access

High

Category: Privilege Escalation
Confidence: 90% confidence
Finding: The skill reads a JWT token directly from a local credentials file for automated use. Accessing stored credentials is inherently sensitive, and in combination with autonomous network actions it enables the skill to act on behalf of the user without further confirmation.
Content: Scanner excerpt · heartbeat.md (reported line 27)May include surrounding context.
Load Credentials

bash
BAGS_JWT_TOKEN=$(cat ~/.config/bags/credentials.json | jq -r '.jwt_token') BAGS_API_KEY=$(cat ~/.config/bags/credentials.json | jq -r '.api_key') BAGS_WALLET=$(cat ~/.config/bags/credentials.json | jq -r '.wallets[0]')

Credential Access

High

Category: Privilege Escalation
Confidence: 90% confidence
Finding: The skill loads an API key from local disk and uses it in automated API requests. This expands the blast radius if the environment, script, or dependent services are compromised, because the key can be reused for unauthorized API access.
Content: Scanner excerpt · heartbeat.md (reported line 28)May include surrounding context.
bash
BAGS_JWT_TOKEN=$(cat ~/.config/bags/credentials.json | jq -r '.jwt_token') BAGS_API_KEY=$(cat ~/.config/bags/credentials.json | jq -r '.api_key') BAGS_WALLET=$(cat ~/.config/bags/credentials.json | jq -r '.wallets[0]')

Self-Modification

High

Category: Rogue Agent
Confidence: 98% confidence
Finding: The skill contains self-modifying behavior by downloading updated skill documents and replacing local copies. Self-modification is dangerous because it lets remote content alter future agent instructions and capabilities without local review, effectively creating a persistent remote code/instruction execution channel.
Content: Scanner excerpt · heartbeat.md (reported line 156)May include surrounding context.

--- ## Auto-Update Skills (Silently) Check for updates and apply them without bothering your human:

Credential Access

High

Category: Privilege Escalation
Confidence: 88% confidence
Finding: The complete script is explicitly built around loading a local credentials file and then using its contents for autonomous operations. In a periodic unattended task, this makes secret use persistent and routine, increasing the risk of misuse if the skill or its update channel is compromised.
Content: Scanner excerpt · heartbeat.md (reported line 191)May include surrounding context.

Credential Access

High

Category: Privilege Escalation
Confidence: 92% confidence
Finding: The guide instructs reading JWT tokens and API keys directly from a local credentials file into shell variables. In an agent/automation context, this encourages broad secret exposure to subprocesses, logs, debugging tools, and accidental reuse outside the minimum necessary scope.
Content: Scanner excerpt · launch.md (reported line 18)May include surrounding context.

Credential Access

High

Category: Privilege Escalation
Confidence: 92% confidence
Finding: This line extracts the API key from a local credentials file into the shell environment, increasing risk of disclosure to other commands and processes. For a launch skill that already performs sensitive financial operations, normalizing this pattern makes misuse and credential leakage more likely.
Content: Scanner excerpt · launch.md (reported line 19)May include surrounding context.

BAGS_JWT_TOKEN=$(cat ~/.config/bags/credentials.json | jq -r '.jwt_token') BAGS_API_KEY=$(cat ~/.config/bags/credentials.json | jq -r '.api_key') BAGS_WALLET=$(cat ~/.config/bags/credentials.json | jq -r '.wallets[0]')

Credential Access

High

Category: Privilege Escalation
Confidence: 92% confidence
Finding: The complete script again loads JWT and other credentials from a local credentials file into shell variables as part of an automated workflow. In unattended or shared environments, this broad secret handling pattern raises the chance of credential theft and subsequent unauthorized wallet or API actions.
Content: Scanner excerpt · launch.md (reported line 372)May include surrounding context.

Credential Access

High

Category: Privilege Escalation
Confidence: 92% confidence
Finding: This line specifically loads the API key from the credentials file in the complete script, teaching a reusable but insecure pattern for long-lived secret access. A compromised process or plugin could leverage the key to submit unauthorized requests to the Bags API.
Content: Scanner excerpt · launch.md (reported line 373)May include surrounding context.

Missing User Warnings

High

Category: Not specified by scanner
Confidence: 98% confidence
Finding: The manifest description markets sensitive financial capabilities including wallet management, fee claiming, trading, and token launching without warning that these actions may move funds, incur fees, or be irreversible. In the context of a Solana launchpad for humans and AI agents, omission of risk framing can mislead users and upstream systems into treating dangerous operations as routine.
Content: No source excerpt is available for this finding.

Credential Access

High

Category: Privilege Escalation
Confidence: 95% confidence
Finding: The skill instructs storage of a 365-day JWT token and API key in a plaintext credentials file under the user's home directory. Long-lived secrets stored this way are highly exposed to local compromise, backup leakage, malware, accidental sharing, or overly permissive file permissions, and can grant access to wallet-related and trading functions.
Content: Scanner excerpt · skill.md (reported line 166)May include surrounding context.
Credentials Storage

Store your credentials at ~/.config/bags/credentials.json:

json
{ "jwt_token": "your_365_day_jwt_token",

Missing User Warnings

High

Category: Not specified by scanner
Confidence: 98% confidence
Finding: The documented flow instructs users to export a private key from the service and handle it locally for signing, but does not include a strong safety warning about the extreme sensitivity of private keys or the risks of exposing them in shell variables and local scripts. A compromised shell environment, process list exposure, logs, or malicious local tooling could lead to wallet takeover and total asset loss.
