Tool: Retire.js for Static Vulnerability Analysis

[Mr-Weather]

Installation: Added as a devDependency via "npm install --save-dev retire"

Evidence: see retire-terminal-output.json committed in this branch.

Pros:

• Zero configuration needed: works out of the box on any Node.js project
• Actively maintained vulnerability database
• Multiple output formats make it easy to integrate into CI
• Fast even on large dependency trees like NodeBB's
• Directly actionable results: tells you which package is vulnerable and what version fixes it

Cons:

• Only catches known vulnerabilities: won't find novel bugs or logic errors
• Can produce false positives for vulnerabilities in code paths never actually used
• Results go stale quickly; needs to be re-run regularly as the database updates
• Purely dependency-focused: doesn't analyze your own source code at all

[Mr-Weather]

• Retire.js is a dependency vulnerability scanner for Node.js projects that will check the installed packages against a known vulnerability database and flags any dependencies that have reported security issues. [https://retirejs.github.io/retire.js/]
• The tool is used for static analysis.
• It can catch known CVEs and reported vulnerabilities in third-party dependencies. It won't catch anything in your own source code and is only about what packages we've pulled in and whether those packages have documented security issues.
• This tool almost doesn't need configuration. For customization, we can pass flags to control output format or add a .retireignore file to limit its findings.
• It better runs as part of CI on every PR so we won't let vulnerable dependencies enter the main. It could work sufficiently if running weekly besided PR checks. And we could also add it as an npm script to run before opening PR.
• There exists false positives as it will flag vulnerabilities if your project never actually exercises that path. False negatives are almost inevitable as novel bugs in dependencies are completely undetectable. For a large codebase like NodeBB, true positive reports about things we don't care about are also a common thing due toits deep dependency tree.
