Framework guides, benchmarks, incident-style research, and CI workflows for Python teams that want lower-noise AppSec and better AI-generated code review.
Articles across Python security, AI code risk, dead code, CI hardening, and workflow changes.
Curated discovery paths so readers can scan by job-to-be-done instead of publish date.
Guides, benchmarks, case studies, comparisons, and research pieces with clear next steps.
Start here
Use these paths when you already know what you need: compare scanners, review AI-generated code, understand framework-specific signal, or dig into proof-heavy benchmarks.

AI coding agents can edit files, run commands, add dependencies, call tools, and open pull requests. Use this security checklist before you let Claude Code, Cursor, Codex, Copilot, Devin, or other agents work in production repositories.
Why this is worth your time
Useful if your team has moved from AI autocomplete to AI coding agents and needs concrete guardrails before those agents touch production repos.
AI coding agent security is different from AI autocomplete security because agents can take actions: edit files, run commands, install packages, call tools, and produce PRs.
The highest-risk controls are not exotic: restrict repo trust, review agent instructions and tool config, gate dependency changes, scan diffs, and block removed auth or validation before merge.
Do not rely on the agent that wrote the code to be the only reviewer of that code. Use deterministic local and CI checks before human approval.
Library
CI/CD YAML should be reviewed like privileged code because it controls tokens, secrets, artifacts, release jobs, and deployment paths.
What you'll get
Use this if you want to treat CI/CD workflow files like privileged code and catch high-risk GitHub Actions or GitLab CI patterns before merge.
Veracode's late-2025 and Spring 2026 GenAI Code Security Reports place the AI-generated code vulnerability rate around 45 percent across 100+ models, with Python around 38 percent in the October 2025 language breakdown.
What you'll get
Useful if you are trying to convince a team, a security reviewer, or a budget owner that AI-generated Python code needs deterministic gates, not just another reviewer.
AI code review security should check both newly introduced vulnerabilities and security controls that disappeared from the diff.
What you'll get
Useful if your team uses Cursor, Claude Code, Copilot, Codex, or other AI coding tools and needs a practical PR security checklist instead of another generic AI security overview.
The useful test for dead-code detection is not whether a scanner prints findings; it is whether maintainers accept the cleanup.
What you'll get
A proof-led explanation of dead-code false positives, maintainer review, and the difference between benchmark signal and real cleanup work.
The market is mixing together three different jobs: AI review assistance, traditional SAST, and AI-specific regression detection.
What you'll get
Useful if you are trying to choose the right security workflow for AI-generated code instead of buying the loudest new category label.
Flask security issues rarely come from Flask itself. They come from the raw Python and library calls Flask apps make around requests, templates, files, and subprocesses.
What you'll get
This completes the Django / FastAPI / Flask framework cluster and gives Python teams a cleaner way to evaluate scanner coverage by framework.
LLMs invent Python packages that don't exist. Attackers register them. Academic research shows 43% of hallucinated names recur on every re-run of the same prompt — turning a model quirk into a repeatable attack surface. Here's what the peer-reviewed data says, and how to catch hallucinated imports at PR time.
What you'll get
This is the sharpest current writeup on hallucinated Python imports and why they turn into a repeatable supply-chain problem.
The old `python.linting.*` settings are deprecated; VS Code now expects dedicated tool extensions.
What you'll get
High-intent migration query with a direct path from editor setup into security scanning.
We ran Skylos on popular open source Python projects, submitted pull requests to remove dead code, and all three were merged by maintainers. Here's what we found, how the LLM verification agent worked, and what the maintainers said.
What you'll get
Proof beats theory. This is the strongest evidence that the dead-code signal survives real maintainer review.
FastAPI's async-first design and Pydantic validation prevent some bugs but introduce others. Here are 8 real vulnerability patterns in FastAPI applications — from SSRF in background tasks to Pydantic validation bypass — and how to detect them with static analysis.
What you'll get
Use this if your team ships async Python APIs and wants concrete FastAPI vulnerability patterns, not generic SAST advice.
Django's ORM prevents SQL injection — until your code uses raw(), .extra(), or cursor.execute(). Here are 7 real vulnerability patterns in Django applications, which tools detect each one, and how to test them yourself.
What you'll get
The Django guide is the clearest framework-specific entry point for teams comparing Python security scanners.
A side-by-side comparison of Python static analysis tools for security, dead code, framework awareness, speed, and CI/CD integration.
What you'll get
This is the fastest way to understand where Bandit, Vulture, and Skylos differ before you install anything.
We ran static analysis on FastAPI, Flask, Pydantic, Rich, Requests, httpx, Click, Starlette, and tqdm. The results: 1,800 security findings, 4,195 quality issues, and 730 pieces of dead code across 9 widely used Python packages.
What you'll get
This is the broadest benchmark in the library set and the best top-level proof page for signal and tradeoffs.
We ran Skylos and Vulture on the Flask repository. Skylos found all 7 dead items with 12 false positives. Vulture found 6 but produced 260 false positives. Here's the full breakdown with real output.
What you'll get
This benchmark shows what framework awareness changes on a real Flask codebase instead of a toy example.
Every unused function in your Python codebase is attack surface you don't need. Here's how dead code creates real security risks, why it gets worse with AI-generated code, and how to detect and remove it systematically.
What you'll get
Start here if you want the strategic reason dead code belongs in an AppSec workflow, not just a cleanup backlog.
AI generates code faster than teams can review it. Here's why the AI PR flood is breaking code review, and how to automate security and quality gates without turning senior engineers into lint bots.
What you'll get
Good starting point if your team’s problem is review overload, not just individual vulnerabilities.
LLMs write code fast but introduce security flaws. Here's why AI-generated Python code fails security checks, the most common vulnerability patterns from Copilot, Claude, and Cursor, and how to detect them with static analysis.
What you'll get
Use this for the broad executive argument that AI-generated Python code needs a security verification layer.
Static Application Security Testing is supposed to catch vulnerabilities before they ship. In practice, noisy SAST results often get ignored. Here's why, and how taint analysis and framework awareness fix it.
What you'll get
Best read for teams trying to understand why SAST noise happens before they compare tools.
