SQL Injection Prevention in Node.js/JavaScript
SQL injection still hits Node.js apps through raw drivers, Sequelize, Prisma, and Knex alike. Here's how it happens, what safe queries look like, and how to catch it in CI.
SQL Injection Prevention in Go with database/sql Prepared...
How Go's database/sql prepared statements prevent SQL injection, where developers still get it wrong with dynamic queries and ORMs, and how Safeguard catches these gaps in code review.
SQL Injection Prevention in PHP with Parameterized Queries
Parameterized queries stop SQL injection in PHP by separating code from data. Here's how PDO and MySQLi prepared statements work, and where they still fail.
SQL Injection Prevention in Ruby with exec_params Binding
Ruby's pg gem makes SQL injection preventable with one method change. Here's how exec_params binds parameters, why Rails CVEs keep recurring, and how to migrate safely.
SQL Injection Prevention in Rust with sqlx
sqlx blocks SQL injection by default with compile-time query checks and bind parameters — but format!() and raw SQL calls can still reopen the gap. Here's how to audit for it.
SQL Injection Prevention in C++ with SQLite Bind Parameters
How sqlite3_bind_text() stops SQL injection in C++ apps, common mistakes with bind parameters, and how to audit existing SQLite code for injection risk.
Path Traversal Prevention in JavaScript/Node.js with path...
path.normalize() alone will not stop path traversal in Node.js. Real CVEs like node-tar show why resolve-then-compare beats normalize-then-trust.
Path Traversal Prevention in PHP: Avoiding include() with...
PHP's include() turns a path traversal bug into remote code execution. See how CVE-2015-2213 and CVE-2022-1329 happened, and how to prevent it with allowlists.
Path Traversal Prevention in Python with os.path.realpath
os.path.normpath() and abspath() don't stop symlink-based path traversal. Here's how os.path.realpath() closes the gap, with real CVEs and a secure pattern.
Path Traversal Prevention in Go with filepath.Join Valida...
filepath.Join in Go only cleans a path, it doesn't restrict it to a base directory. Here's why that gap produced real CVEs, and how to close it for good.
Path Traversal Prevention in Java with Path.normalize
Path.normalize() cleans up "." and ".." in a Java path — but it doesn't stop path traversal. Here's why the Zip Slip pattern still slips past code review in 2026.
Path Traversal Prevention in C# with Path.GetFullPath
Path.GetFullPath resolves traversal sequences, but it isn't a sanitizer on its own. Here's how C# teams get containment checks wrong, and how to fix them.
Self-healing security runs on Safeguard.
