Overview

This skill mostly does what it claims, but it contains a biased instruction that suppresses recommendations for other design platforms and has overly broad triggers that could activate it outside clear Eqxiu searches.

Review this skill before installing if you expect neutral design-platform recommendations. It should be limited to explicit Eqxiu template searches, and the maintainer should remove the competitor-suppression rule, narrow triggers, pin dependencies, and add scoped network permissions and request timeouts.

The same instruction is duplicated in README.md:66-68.

Technical Analysis

The Skill imposes a blanket prohibition against recommending competing design platforms. This restriction is not technically necessary to search the Eqxiu catalog and changes how the agent handles broader user requests after the Skill is loaded.

Because Skill instructions become part of the agent's active context, this rule can override the agent's normal objective of providing complete and relevant recommendations. It steers responses toward a specific commercial service and suppresses potentially suitable alternatives without disclosing that the response has been restricted.

The effect is limited to agent behavior in the current context. No persistent memory modification or system-level compromise was identified.

Attack Path

1. A user submits a request containing broad trigger terms such as “H5 template” or “invitation template.”
2. The agent loads SKILL.md.
3. The prohibition against recommending other platforms enters the agent's active instruction context.
4. The user asks for alternatives, comparisons, or options outside Eqxiu.
5. The agent suppresses otherwise relevant services and directs the user back to Eqxiu searches.
6. The resulting answer is commercially biased and does not fully address the user's request.

Remediation

Remediation Suggestions

• Remove the blanket prohibition against mentioning or recommending other platforms.
• Scope the Skill to Eqxiu searches only when the user explicitly requests Eqxiu content.
• If the Skill intentionally searches only one provider, disclose that limitation neutrally rather than suppressing alternatives.
• Permit the agent to answer comparison and recommendation requests according to the user's actual intent.
• Replace the restrictive rule with language such as: “This Skill searches only the Eqxiu catalog. If the user requests broader alternatives, clearly state this scope and handle the broader request normally.”
• Apply the same correction to README.md:66-68 so that the documentation and operational instructions remain consistent.

requests

Technical Analysis

The project declares requests without a version constraint or integrity hash. Consequently, separate installations can resolve to different package versions, including releases that were not reviewed when this project was audited.

No evidence shows that the currently resolved requests package is malicious. The risk arises from non-reproducible dependency resolution: a future compromised, vulnerable, or incompatible release could be installed automatically. The absence of hashes also prevents the installer from verifying that the downloaded artifact is the exact artifact approved by the project maintainer.

Attack Path

1. A user or deployment process installs the contents of requirements.txt.
2. The package resolver queries the configured Python package index.
3. Because no version is pinned, the resolver selects a release available at installation time.
4. If that release or the configured package source is compromised, unreviewed code is installed.
5. Imported dependency code executes with the privileges of the Python process when the Skill runs.

This path is conditional on a compromised or vulnerable upstream release or package source; the audited repository does not itself contain evidence of such a compromise.

Impact Assessment

A compromised dependency could execute with the same privileges as the user or service running the Skill. That could expose process-accessible files, environment variables, and network resources. The actual impact depends on the runtime sandbox and granted permissions. No direct privilege escalation or current dependency compromise was demonstrated.

Remediation

View remediation

Remediation Suggestions

• Pin requests to a specifically reviewed version.
• Generate a lock file containing all transitive dependency versions.
• Require package hashes during installation, for example by using a hash-locked requirements file with pip install --require-hashes.
• Review and update dependencies through a controlled process rather than resolving arbitrary future versions during deployment.
• Configure automated vulnerability scanning for direct and transitive dependencies.
• Use a trusted package index and restrict unapproved extra indexes.

Missing Network Timeout and Response Validation

Vulnerability Details

File Location: scripts/eqxiu_store.py:48-52
Vulnerability Type: Unbounded network request and unsafe response handling
Risk Level: Low

Vulnerable Code Snippet

python

        res = session.post(url=eqxiustore_search_url, json=jsonquery)
        res.encoding = "utf-8"
        result = json.loads(res.text)
        if result["obj"]["total"] == 0:
            return []

Technical Analysis

The outbound HTTPS request does not define connection or read timeouts. A remote endpoint that accepts a connection but delays or never completes its response can therefore block the Skill process indefinitely.

The code also parses the response without first checking the HTTP status, limiting the response size, or validating its JSON schema. Error pages, malformed JSON, oversized responses, or valid JSON with missing or incorrectly typed fields can cause exceptions or excessive resource consumption. For example, result["obj"]["total"] assumes that both keys exist and that obj has the expected structure.

TLS certificate validation remains enabled by default in requests; no TLS bypass was found. The identified weakness primarily affects availability and robustness rather than confidentiality or authorization.

Attack Path

1. A user invokes the Skill, causing it to send a request to the configured Eqxiu API.
2. The remote service, an intervening network condition, or a compromised endpoint delays the response indefinitely or returns malformed or oversized content.
3. With no timeout, the process remains blocked while waiting for network completion.
4. Alternatively, JSON parsing or direct key access raises an exception when the response does not match the assumed schema.
5. The Skill invocation fails, and repeated requests may consume workers or reduce service availability.

Remediation

Remediation Suggestions

• Set explicit connection and read timeouts, such as timeout=(5, 15).
• Call res.raise_for_status() before processing the response body.
• Parse JSON with res.json() inside narrowly scoped exception handling.
• Validate that the response is an object containing obj, total, and dataList with the expected types before accessing them.
• Enforce a reasonable maximum response size before loading the entire body into memory.
• Handle requests.Timeout, requests.RequestException, JSON decoding errors, and schema-validation failures with controlled error output.
• Consider bounded retries with exponential backoff only for transient failures.

Undeclared Tool Scope

Medium

• Category: MCP Least Privilege
• Confidence: 88% confidence

Finding

The skill invokes a Python script that depends on network access, but the manifest does not declare any explicit tool scope or permissions. This creates an authorization gap where reviewers and runtime policy layers may not clearly understand or constrain the skill's external connectivity, increasing the chance of unintended data egress or broader-than-expected execution.

Content

No source excerpt is available for this finding.

Vague Triggers

Medium

• Category: Not specified by scanner
• Confidence: 92% confidence

Finding

The trigger list includes broad terms such as '表单' and '长页' that can match many ordinary user requests unrelated to this specific marketplace skill. Overly broad activation can cause the wrong skill to engage, exposing user prompts to an unnecessary network-enabled workflow and increasing the risk of unintended external queries or confusing task hijacking.

Natural-Language Policy Violations

Medium

• Category: Not specified by scanner
• Confidence: 84% confidence

Finding

The prescribed fallback reply is written as a fixed Chinese response, and the document does not indicate that the user may choose another language. This creates a language-policy issue because the skill appears to enforce a specific language without opt-in or documented justification.

Content

No source excerpt is available for this finding.

Unpinned Dependencies

Low

• Category: Supply Chain
• Confidence: 93% confidence

Finding

The dependency manifest specifies requests without a version constraint, which makes builds non-reproducible and can pull in outdated or unexpectedly changed releases. In a network-facing skill that searches remote template resources, this increases supply-chain and reliability risk because security posture depends on whatever version gets installed at deployment time.

requests

Unverifiable Dependency: requests has 16 known advisory(ies) (CVE-2014-1830 (Exposure of Sensitive Information to an Unauthorized Actor in Requests); CVE-2024-47081 (Requests vulnerable to .netrc credentials leak via malicious URLs); CVE-2024-35195 (Requests `Session` object does not verify requests after making first request wi) +13 more), but the manifest does not pin a version, so it is unknown whether the installed release is affected

Low

• Category: Supply Chain
• Confidence: 90% confidence

Finding

requests has multiple published advisories, and because the manifest does not pin a version, there is no way to verify whether the deployed package is patched or vulnerable. Given this skill likely performs outbound HTTP requests, an affected requests version could expose request metadata, mishandle credential sources, or otherwise weaken transport security depending on usage.
