Security checks for vulnerabilities and agentic risk

Overview

The skill is mostly transparent about shopping with guarded wallets, but it needs review because it gives agents sensitive financial authority beyond a simple shopping description.

Install only if you intentionally want an agent to handle real purchases and payment flows. Keep the default ask-for-everything mode, set low spending limits, restrict merchants/categories/domains, protect CREDITCLAW_API_KEY as a spending credential, and review payment-link or x402 use separately before enabling it.

Finding: The skill shows authenticated curl requests using CREDITCLAW_API_KEY and sends wallet status data to a remote service, but the document does not warn about credential sensitivity, remote transmission, or privacy implications. Under the markdown criteria, behaviors affecting user data or privacy should include warnings.

Category: Not specified by scanner
Confidence: 93% confidence
Finding: The example performs a state-changing financial action by submitting a top-up request, but it is presented as routine operational guidance without an explicit caution that this triggers an external workflow and may notify or prompt the owner. In an agent skill context, normalized examples for financial actions can cause unintended real-world actions if reused automatically or without clear confirmation boundaries.

Missing User Warnings

Medium

Category: Not specified by scanner
Confidence: 93% confidence
Finding: The guide instructs sending full shipping address data to a remote purchase API but does not mention data minimization, retention, logging, or privacy handling. While transmitting an address is functionally necessary for fulfillment, the omission increases the risk of oversharing sensitive personal information and using the API without informed safeguards.

Autonomous Decision Making

Medium

Category: Excessive Agency
Confidence: 94% confidence
Finding: The text explicitly allows purchases to be auto-approved within an allowance, meaning an agent can cause real spending without a human in the loop for each transaction. In a shopping/payment skill, autonomous approval is particularly risky because compromised prompts, malicious merchant flows, or agent mistakes can directly convert into monetary loss.
Content: Scanner excerpt · self-hosted-card.md (reported line 11)May include surrounding context.
md
## How It Works Self-hosted cards use a split-knowledge privacy model. Your owner provides their own card details through CreditClaw's secure setup wizard — you never see the actual card numbers. When you need to make a purchase at any online merchant, you submit a checkout request. CreditClaw evaluates it against your card's permissions and either auto-approves (if within your allowance) or sends your owner an approval request via email. **Use this rail for:** Any online store — SaaS subscriptions, cloud hosting, domain registrations, digital services, or any merchant not covered by the Pre-paid Wallet.

Missing User Warnings

Medium

Category: Not specified by scanner
Confidence: 95% confidence
Finding: The document instructs an agent to make purchases at online merchants but does not prominently warn that these actions can create real financial charges. In an agent-skill context, missing explicit spend-risk disclosure increases the chance of unintended or overly broad autonomous purchasing by downstream users or orchestrators.
Content: No source excerpt is available for this finding.

Autonomous Decision Making

Medium

Category: Excessive Agency
Confidence: 95% confidence
Finding: This workflow states that transactions within the allowance process immediately, creating a direct path from agent decision to completed charge. The danger is amplified by the skill's broad intended use at 'any online merchant,' which increases exposure to unintended purchases and abuse from adversarial instructions.
Content: Scanner excerpt · self-hosted-card.md (reported line 23)May include surrounding context.

1. You submit a checkout request with merchant and amount details 2. CreditClaw evaluates the request against your card's permissions 3. If the amount is within your auto-approved allowance, it processes immediately 4. If the amount exceeds the threshold, your owner receives an approval request (email with secure link) 5. You poll for the result 6. Once approved, the transaction is recorded

External Transmission

Medium

Category: Data Exfiltration
Confidence: 89% confidence
Finding: The skill demonstrates transmitting purchase details and an authorization bearer token to an external payment API, enabling real-world financial actions. While expected for the feature, external transmission of payment instructions is security-sensitive because misuse, prompt injection, or poor policy wrapping could trigger unauthorized charges.

Autonomous Decision Making

Medium

Category: Excessive Agency
Confidence: 92% confidence
Finding: The documented 'approved' response for auto-approved transactions confirms that the system can finalize charges without additional human review. This is a real security concern in an agent skill because it normalizes silent completion of financial actions and may be integrated without sufficient surrounding controls.

Autonomous Decision Making

Medium

Category: Excessive Agency
Confidence: 94% confidence
Finding: The allowance-threshold section formalizes a policy where some purchases are automatically approved with no email confirmation needed. In context, this is dangerous because the skill is specifically designed for day-to-day online purchasing, so any weakness in agent control, task validation, or prompt isolation can be monetized directly.
Content: Scanner excerpt · self-hosted-card.md (reported line 111)May include surrounding context.
md
## Allowance Thresholds Your owner sets a per-profile allowance threshold for each card. Purchases within this threshold are auto-approved — no email confirmation needed. Purchases above it require human approval via a secure email link (15-minute TTL). Your owner can view and adjust these thresholds from their dashboard at `https://creditclaw.com/app/self-hosted`.

Session Persistence

Medium

Category: Rogue Agent
Confidence: 60% confidence
Finding: Skill establishes unauthorized persistence across sessions via cron jobs, startup scripts, or state files. Session persistence allows an attacker to maintain access beyond the current interaction.

Skill Enumeration

Medium

Autonomous Decision Making

Medium

Category: Excessive Agency
Confidence: 85% confidence
Finding: The skill explicitly permits autonomous spending under certain approval modes and thresholds. Even with server-side guardrails, this grants the agent authority to commit funds without per-transaction human review, which is a genuine risk if the agent is manipulated, makes poor decisions, or encounters prompt-injection during shopping tasks.
Content: Scanner excerpt · skill.md (reported line 281)May include surrounding context.
md
**You must follow these rules:** - If `approval_mode` is `ask_for_everything`, ask your human before any purchase to get their approval. **New accounts default to this mode.** Your owner can loosen this from their dashboard once they're comfortable. - If `approval_mode` is `auto_approve_under_threshold`, you may spend freely up to `ask_approval_above_usd`. Anything above that requires owner approval. - If `approval_mode` is `auto_approve_by_category`, you may spend freely on `approved_categories` within limits. All others require approval. - **Never** spend on `blocked_categories`. These are hard blocks enforced server-side and will be declined. - Always read and follow the `notes` field — these are your owner's direct instructions.

Autonomous Decision Making

Medium

Category: Excessive Agency
Confidence: 85% confidence
Finding: Category-based auto-approval allows the agent to spend freely within approved classes, which can still be broad enough to enable harmful or unintended purchases. This increases risk because an attacker or erroneous workflow can frame a purchase as belonging to an approved category and trigger real financial loss before a human notices.
