socket.emit()
,socket.on()
: These methods send and handle custom events. If event names or data are user-controlled and not sanitized, they could potentially lead to Code Injection attacks.
Mongoose-Related Exploits:
Mongoose provides a straightforward, schema-based solution to model your application data for MongoDB.
.find()
,.findOne()
,.update()
: These Mongoose methods can potentially be used for NoSQL Injection attacks if the filter or update objects contain user-controlled input and are not properly sanitized.mongoose.connect()
: Connects to a MongoDB database. If the connection string is user-controlled, this could potentially lead to SSRF or unauthorized access to the database.
Electron-Related Exploits:
Electron is a framework for creating native applications with web technologies like JavaScript, HTML, and CSS.
webContents.executeJavaScript()
: This method can be used to run JavaScript on the renderer process (web page). If user-controlled input is injected into this function without proper sanitization, it could lead to Remote Code Execution.webContents.loadURL()
: This method loads the URL in the window. If the URL is user-controlled and not validated, it could lead to Universal Cross-site Scripting (UXSS) or Remote Code Execution.shell.openExternal()
: This method opens the given external protocol URL in the desktop's default manner. If the URL is user-controlled and not validated, it could be used for URL Scheme Hijacking attacks.new BrowserWindow()
: If thenodeIntegration
orcontextIsolation
options are not set correctly when creating new windows, it could lead to Remote Code Execution.
D3.js-Related Exploits:
D3.js is a JavaScript library for producing dynamic, interactive data visualizations in web browsers.
d3.json()
,d3.csv()
,d3.xml()
: These methods load external JSON, CSV, or XML data. If the URL or the way the data is used is user-controlled and not properly validated or sanitized, it could lead to Data Injection attacks or Cross-Site Scripting.d3.select()
,d3.selectAll()
: These methods select an element or elements from the document. If the selector is user-controlled and not properly sanitized, it could potentially be used for DOM-Based Cross-Site Scripting attacks.
Lodash-Related Exploits:

Knex.js-Related Exploits:
Knex.js is a "batteries included" SQL query builder for Postgres, MSSQL, MySQL, MariaDB, SQLite3, Oracle, and Amazon Redshift.
knex.raw()
: This function allows raw SQL to be executed. If the raw SQL includes user-controlled input, it could potentially lead to SQL Injection attacks.knex.select()
,knex.where()
: These methods are used to build queries. If the column names or values are user-controlled and not validated, they could potentially lead to SQL Injection attacks.
Moment.js-Related Exploits:
Moment.js is a free and open-source JavaScript library that removes the need to use the native JavaScript Date object directly.
moment.parseZone()
: This method parses a string and converts it into a moment object in a specified timezone. If the input string is user-controlled and not validated, it could potentially lead to Parsing Manipulation attacks.moment.tz()
: This function allows for converting dates between timezones. If the timezone parameter is user-controlled and not validated, it could potentially lead to Timezone Manipulation attacks.
