nodejsscan is a static analysis security tool and vulnerability detection engine designed to scan Node.js source code for security flaws and common coding vulnerabilities. It functions as a static application security testing tool that analyzes code without executing the program. The tool operates as a security linter that can be integrated into continuous integration pipelines to block insecure code from merging into main branches. It automates the auditing process through rule-based detection and pattern-based static analysis. The project provides capabilities for vulnerability alert autom

CodeQL is a semantic code analysis engine and vulnerability scanning tool that treats source code as data. It utilizes a static analysis query language to define complex patterns and security vulnerabilities within a code graph database. The system represents source code as a relational database, enabling the execution of structural queries and data flow analysis. This approach allows for the detection of security flaws and coding errors across large-scale repositories. The tool provides capabilities for automated code auditing, static analysis security testing, and custom vulnerability dete

Bearer is a static analysis security testing tool and privacy compliance auditor. It identifies security vulnerabilities, hard-coded secrets, and privacy risks in source code through static analysis and data flow tracing. The tool distinguishes itself by tracking the movement of sensitive data through code to identify leaks and by mapping personal and health-related information flows to generate evidence for privacy impact assessments. It also provides differential scanning for pull requests and uses fingerprint-based suppression to exclude known false positives from reports. The platform co

Brakeman is a static analysis security tool and scanner specifically designed for Ruby on Rails source code. It identifies common security vulnerabilities, such as injection and cross-site scripting, by analyzing the application codebase without executing the application. The tool functions as a security auditor that detects mass assignment risks and template vulnerabilities. It evaluates the final output of rendered views and identifies unrestricted assignment patterns that could allow unauthorized modification of model attributes. The system provides vulnerability management through the us

Semgrep is a static analysis security testing tool designed to identify vulnerabilities and logic errors by matching source code against declarative patterns. It functions as an automated scanner that integrates into development workflows to detect insecure code patterns and enforce coding standards before deployment. The engine utilizes a language-agnostic intermediate representation and a modular parser architecture to normalize diverse programming languages into a unified format. This allows for consistent rule execution across different codebases, enabling users to perform custom structur

Infer is a static analysis toolset for Java, C, C++, and Objective-C designed to detect memory leaks, null dereferences, and resource bugs. It functions as a multi-language bug finder that identifies race conditions, deadlocks, and memory safety issues by translating source code into a common intermediate representation for analysis. The project distinguishes itself through an inter-procedural data flow analyzer that tracks movement between sources and sinks to detect tainted flows and generate data flow graphs. It also includes a framework for verifying temporal properties and reachability u

SVF is an open-source static program analysis framework and points-to analysis library that tracks memory references, variable aliases, and data dependencies across whole programs. The platform translates compiled intermediate code formats into unified internal representations, constructing constraint graphs, call graphs, and control-flow graphs to model interprocedural execution behavior and memory state. The framework incorporates specialized engines for flow-sensitive, flow-insensitive, and context-sensitive pointer analysis alongside sparse value-flow graph generation. It features memory

Bandit is a static analysis security testing tool and vulnerability detection scanner for Python source code. It functions as a security-focused linter and static analyzer that identifies common vulnerabilities and architectural flaws without executing the program. The tool utilizes an abstract syntax tree to analyze code patterns and identifies risky function calls or insecure configurations. It employs a plugin-based rule engine to decouple scanning logic from individual security checks and supports configuration-driven filtering to exclude specific files or ignore certain warnings. The sy

Flare-floss is a security utility and static binary string extractor designed to uncover hidden text and configuration data within compiled binaries. It functions as an obfuscated string decoder and reverse engineering tool to translate encoded strings into readable text for security auditing. The project employs emulated execution to capture the decrypted state of strings in memory by running small chunks of binary code in a virtual CPU. It further utilizes static analysis disassembly, intermediate representation analysis, and heuristic-based pattern matching to identify and decode strings t

This project provides an integration of Tree-sitter into the Neovim editor to enable structural code analysis. It serves as a framework for structural code navigation, context-aware syntax highlighting, and the management of language-specific parsers. The system distinguishes itself through a multi-language injection handler that identifies and parses embedded languages within a single document. It uses a dedicated parser manager to install, update, and remove grammar definitions and their associated query files. The tool covers several capability areas including incremental text selection,
