The One Line of Ordinary Code That Kills a Taint Engine
param = decode(param) is as common as code gets. In a dataflow engine that resolves variables by looking backwards, it can recurse forever — and in Go the resulting stack overflow cannot be caught.
Reading an OWASP Benchmark Score Without Being Sold To
A tool that flags every test case scores 100% detection on the OWASP Benchmark. Recall is the number vendors quote and the one that means least — here is what the suite actually measures.
What Tree-sitter Taint Analysis Actually Catches (and What It Cannot)
Following untrusted data from source to sink across a real codebase is a solved problem right up until reflection, dynamic dispatch and an ORM turn up. Knowing where the analysis stops is what makes it usable.
Recall Is Easy. Your SAST Tool's Real Metric Is the Mute Rate
Any scanner can find every vulnerability by flagging everything. The number that decides whether a tool survives contact with a development team is how often it is wrong.
Running the OWASP Benchmark Against Your Own SAST Engine
A scanner with no measured accuracy is a scanner with claimed accuracy. Wiring up the OWASP Benchmark gives you one number that survives scrutiny — and usually finds a crash on the way.
Your Git History Already Knows Which AI Wrote Your Code
Coding assistants sign their own work in the commit trailer block. That makes 'how much of this was AI-written' a parsing problem, not a heuristic one — as long as your tooling reads the commit body, which most of it does not.
AI Writes Code Faster Than You Can Review It. Which Scanner Do You Point at It?
AI-generated code arrives faster than review can absorb and fails in distinct patterns. SAST, DAST, and reachability each catch part of that — and each misses a specific, predictable slice.
Open redirect vulnerabilities explained
Open redirect flaws (CWE-601) score as medium severity alone, but they power real phishing campaigns against Google, Amex, and Microsoft. Here's how they work and how to stop them.
Type confusion vulnerabilities explained
Type confusion bugs let attackers corrupt memory by exploiting mismatched type assumptions. See real CVEs, how JIT engines fail, and how to catch it early.
Format string vulnerabilities explained
Format string bugs let attackers turn a printf call into memory disclosure or arbitrary writes. Here's how CWE-134 works, real CVEs, and fixes.
Code Security Scanners: Choosing One for Your Stack
The right code security scanner depends less on which vendor's marketing sounds best and more on language coverage, false-positive rate, and whether it fits into the workflow developers already use.
Code Security Scan: How to Scan Your Code for Vulnerabilities
A code security scan analyzes your source and its dependencies for security flaws before they ship. Here is how the main scan types work, what tools to use, and how to wire scanning into CI without drowning in noise.
