Payloadsallthethings

Overview

Payloadsallthethings is a web application security tool that appears across web application security workflows in this knowledge base. It is referenced as part of higher-level security analysis, investigation, monitoring, or validation activity rather than as an end in itself.

What It Is

Payloadsallthethings is best understood as a web-application-security tool in this knowledge base. Its role is conceptual and system-facing rather than procedural: it gives analysts or defenders a structured way to examine evidence, model system behavior, or reason about security state.

How It Works

Payloadsallthethings works by turning technical inputs into more interpretable outputs at the system level. Across the source skills, it appears as part of larger analysis, investigation, monitoring, or validation loops rather than as a standalone end state.

Core Concepts

• nosql injection
• mongodb
• authentication bypass
• injection attack
• web security
• database security
• api testing
• web application security
• penetration testing
• ssti
• template injection
• rce

Typical Workflow

• Find parameters where user input is processed by a template engine.
• '<%= 7*7 %>' # ERB (Ruby), EJS (Node.js)

Use Cases

• During web application penetration testing of applications using NoSQL databases
• When testing authentication mechanisms backed by MongoDB or similar databases
• When assessing APIs that accept JSON input for database queries
• During bug bounty hunting on applications with NoSQL backends
• When performing security code review of database query construction
• During authorized penetration tests when user input is rendered through a server-side template engine
• When testing error pages, email templates, PDF generators, or report builders that include user-supplied data
• For assessing applications that allow users to customize templates or notification messages
• When identifying potential SSTI in parameters that reflect arithmetic results (e.g., {{7*7}} returns 49)
• During security assessments of CMS platforms, marketing tools, or any application with templating functionality

Limitations

• Output still depends on context, data quality, and surrounding analysis.
• The tool should be interpreted as part of a broader workflow, not as a complete answer by itself.
• Capabilities and visibility vary depending on environment, integrations, and available inputs.
