What This Extension Does
The Smallpdf%E2%80%94edit Convert Com extension appears to provide a set of tools for editing, converting, and managing PDF files within the browser. Its description suggests it offers features like compression, conversion, merging, e-signing, and splitting.Permissions Explained
- storage: This permission allows the extension to store data locally on the user's device. For an extension that claims to provide PDF tools, this is a standard permission.
- notifications: This permission enables the extension to display notifications to the user. While not uncommon for extensions with interactive features, it may be more noticeable if the extension frequently sends notifications.
- alarms: This permission allows the extension to schedule tasks or reminders. It's less common for productivity tools like this but could be used for features like automatic file conversion or reminder services.
What We Found in the Code
- innerHTML assignment — potential XSS vector [medium]: The use of
innerHTMLcan indeed pose a risk if untrusted data is inserted into it, as it can execute scripts. However, without more context (e.g., whether this is used with user-provided input), it's difficult to assess the severity. In general, usinginnerHTMLfor UI rendering is common and not inherently malicious. - Keyboard listeners: Keyboard listeners are a normal part of web development for implementing shortcuts or interactive features within an extension. Without more information on how these listeners are implemented (e.g., whether they're bound to specific keys or if they're used in conjunction with user input), it's hard to say this is concerning.
External Connections
The extension communicates with several domains, including:- smallpdf.com: Expected for its functionality, as the extension likely uses SmallPDF's services for PDF management.
- pluto.smallpdf.com, pro.smallpdf.com, files.smallpdf.com, sign.com, filestorage.smallpdf.com, task.smallpdf.com, and chatpdf.smallpdf.com: These domains are also related to SmallPDF's services, suggesting they're used for various aspects of the extension's functionality.
- workspace.google.com: This might be expected if the extension integrates with Google Workspace (formerly G Suite) for certain features like document editing or storage integration.
- www.w3.org, reactjs.org, and git.io: These are external resources that could be used for documentation, libraries, or other development purposes. They're not directly related to SmallPDF's services but are common in web development.
Things to Consider
Given the extension's purpose and permissions, it seems to have a broad set of features that might justify its declared permissions. However, users should consider whether they need such extensive PDF management capabilities within their browser. The use ofinnerHTML for UI rendering is not inherently malicious but could pose risks if used with untrusted data. Users may want to review the extension's settings and ensure it doesn't send unnecessary notifications or schedule alarms without their consent.
