REPELSEC

About the tool

A command-line tool allowing developers to find security vulnerabilities within a Java project. This is done through:

• Static Application Security Testing (SAST) run against first party code (.java, .jsp) to identify potential CWE vulnerabilities.
• Software Composition Analysis (SCA) that identifies outdated dependencies within the pom.xml file and their associated CVE vulnerabilities.
