Raining CVEs on WordPress Plugins with Semgrep

Explore a comprehensive conference talk on leveraging Semgrep, an open-source static code analyzer, to identify vulnerabilities in WordPress plugins at scale. Learn how custom rules were developed to scan over 80,000 plugins for SQL injection, cross-site scripting (XSS), and local file inclusion (LFI) vulnerabilities. Discover techniques for reducing false positives, converting time-based blind SQLi to union-based attacks, and bypassing filters. Gain insights into the creation of XSSBomb, an automated XSS validator. Watch demonstrations on basic Semgrep usage, custom rule writing, and running scans on vulnerable plugin repositories. Understand the real-world implications of this research, which resulted in 47 confirmed bugs and assigned CVEs, while also highlighting best practices for secure coding in WordPress.
