[shivasurya]

This pull request updates security review guidelines and issue reporting formats to enhance the depth and clarity of vulnerability analysis, especially for CLI-based and WordPress plugin reviews. The changes emphasize the importance of dataflow and control flow analysis, provide stricter instructions for including context in issue descriptions, and clarify the scope of vulnerabilities to be reported.

Security Review Process Improvements:

• Added instructions to use dataflow and control flow analysis to fully understand the context and reachability of security vulnerabilities, and to include these findings in the report.

Issue Reporting Format Enhancements:

• Updated the <description> field in issue templates to require "additional context" alongside file name, path, and line number for each reported issue.

WordPress Plugin Review Clarifications:

• Specified that vulnerabilities related to SSL bypass or other SSL-related issues should be ignored when reviewing WordPress plugins.
