TIPSemgrep’s Go coverage leverages framework-specific analysis capabilities that are not present in Semgrep Community Edition (CE). As a result, many framework specific Pro rules will fail to return findings if run on Semgrep CE. To ensure full security coverage, run: semgrep login && semgrep ci.

Semgrep Code analyses

​
Coverage

Semgrep aims to provide comprehensive and accurate detection of common OWASP Top 10 issues in source code. Semgrep uses rules, which are instructions based on which it detects patterns in code. These rules are usually organized in rulesets. By default, Semgrep Code provides you with the p/comment and p/default rulesets. These rulesets provide the most accurate and comprehensive coverage across Semgrep’s supported languages. Some examples of rules include:

​
Go support in Semgrep Supply Chain

Semgrep Supply Chain is a software composition analysis (SCA) tool that detects security vulnerabilities in your codebase introduced by open source dependencies.

​
Supported package managers

Semgrep supports the following Go package manager:
  • Go modules (go.mod)

​
Analyses and features

The following analyses and features are available for Go: Reachability analysis Reachability refers to whether or not a vulnerable code pattern from a dependency is used in the codebase that imports it. In Semgrep Supply Chain, both a dependency’s vulnerable version and code pattern must match for a vulnerability to be considered reachable. License detection Semgrep Supply Chain’s license compliance feature enables you to explicitly allow or disallow (block) a package’s use in your repository based on its license. For example, your company policy may disallow the use of packages with the Creative Commons Attribution-NonCommercial (CC-BY-NC) license. Semgrep can help enforce this restriction. Malicious dependency detection Semgrep is able to detect malicious dependencies in your projects and in pull requests (PRs) or merge requests (MRs). SBOM generation Semgrep enables you to generate a software bill of materials (SBOM) to assess your third-party dependencies and comply with auditing procedures. Semgrep Supply Chain (SSC) can generate an SBOM for each repository you have added to Semgrep AppSec Platform.

​
Go support in Semgrep CE

Semgrep CE is a fast, lightweight program analysis tool that can help you detect bugs in your code. It makes use of Semgrep’s LGPL 2.1 open source engine.

​
Analyses

  • Single-file, cross-function constant propagation
  • Single-function taint analysis
  • Semantic analysis

  • Check the license of a rule to ensure it meets your licensing requirements. See Licensing for more details.
The Semgrep Registry provides the following Go rule sets: Sample usage:
