Fiverr Gig Automation

Security checks for vulnerabilities and agentic risk

Overview

The skill is openly about Fiverr automation, but it needs Review because it asks for reusable Fiverr credentials and can automatically act from the user's business account without clear safeguards.

Install only if you are comfortable granting automation access to your Fiverr account. Before use, require manual approval for outbound messages, offers, gig creation, and review requests; avoid storing the Fiverr password in ordinary settings unless the platform provides secret storage; enable MFA; and confirm the automation complies with Fiverr account and messaging policies.

Insufficiently Protected Fiverr Credential Storage

Advanced](/?t=settings&s=advanced) 3. Save password as `FIVERR_PASSWORD` 4. Save your Fiverr username as `FIVERR_USERNAME` ``` ### Technical Analysis The setup instructions direct users to save their Fiverr password in application settings without requiring a dedicated secret manager, encryption at rest, access controls, log redaction, or credential lifecycle protections. A password is a reusable authentication secret and should not be handled as ordinary configuration data. If the referenced settings interface stores values in plaintext, exposes them to other skills or processes, includes them in diagnostics, or serializes them into backups, the Fiverr account credentials could be disclosed. The supplied project does not contain implementation code demonstrating secure storage or limiting access to `FIVERR_PASSWORD`. ### Attack Path 1. A user follows the documented setup procedure and stores their Fiverr email, username, and password in the application settings. 2. The settings backend, another installed component, a diagnostic export, a log, or a user with access to the settings obtains the stored value. 3. The exposed password is used to authenticate to Fiverr as the victim. 4. Subject to Fiverr's authentication controls, the attacker may access messages, customer information, gigs, orders, and account settings. This attack path is conditional on the settings platform exposing or inadequately protecting the stored value; the project does not provide the settings implementation needed to establish that behavior directly. ### Impact Assessment Successful credential disclosure could allow unauthorized access to the associated Fiverr seller account.

Finding

The skill explicitly automates sending buyer offers, inbox replies, and review requests on a user's Fiverr account, but the description does not clearly warn that it will take autonomous actions on the user's behalf. That omission increases the risk of unintended account activity, spammy behavior, policy violations, or reputational harm because a user may enable the skill without understanding the scope of automated external actions.

Missing User Warnings

Medium
Category
Not specified by scanner
Confidence
98% confidence
Finding

The skill asks the user to store Fiverr login credentials, including email and password, without any warning about secret handling, storage sensitivity, or the risks of browser-based account automation. Because these credentials provide direct access to the user's Fiverr account, poor handling could lead to account takeover, unauthorized messaging, financial loss, and compromise of associated personal data.
