Prevent Data Breaches: Top Security Risks and Best Practices

Have you explored the critical Telnet vulnerability, CVE-2026-24061? It’s a fascinating case of environment variable argument injection that allows for complete authentication bypass. I recently built a Python script to demonstrate this exploit and set up a full testing lab using Docker. It was a great way to sharpen my Python automation skills and understand legacy protocol weaknesses. The Docker setup is incredibly straightforward—I highly recommend trying it out to understand the mechanics of the flaw. If you get stuck or want to discuss the exploit, feel free to DM me! https://lnkd.in/g3s-AVTd) #Telnet__Exploit #CVE #CVE_2026_24061

https://lnkd.in/enfXW3GQ — I have been building a Python pentesting lab project to demonstate how web authentication workflows behave under repeated, automated requests. One of my scripts uses threading with a shared Queue to distribute work across multiple workers, while each worker creates its own session via requests.Session() to keep client state (like cookies) consistent across related requests. We make it like that as many websites expect some continuity between requests.

🔐Authentication isn’t magic — it’s logic. This week, I built JWT authentication in FastAPI — and things finally clicked. Instead of just using it… I understood it. Here’s what I explored: 🧩 What’s actually inside a JWT 🔍 How signature verification works ⏳ Why token expiration really matters 📘 How Swagger UI makes API testing seamless If you're working with FastAPI — what was the trickiest part of setting up authentication for you? #FastAPI #BackendEngineering #Python #JWT #SoftwareDevelopment

🚨 High risk vulnerability in Authlib! CVE-2026-28802 allows attackers to bypass signature verification by setting `alg: none` and a blank signature. This issue points out the importance of API security. It's been patched in version 1.6.7, so update ASAP! #Authlib #Python #OAuth #OpenIDConnect #APISecurity #OWASP #CVE202628802 🛡️ https://lnkd.in/g7YS_ka9

🔐Built a JWT Authentication system using FastAPI. Implemented login with OAuth2, password hashing using bcrypt, and protected routes using Bearer tokens. This helped me understand how real-world backend authentication flows work — from token creation to validation and access control. Next step: integrating this into a full CRUD API with a database. #FastAPI #Backend #Python #JWT

Been working these days in a major update for pytest-forger 0.2.0. * Static code analysis with AST * Auto-generated test scaffolding * External dependency detection * Type-aware placeholders * Tests This is a very fresh update with a lot to review, but it's a huge step forward compared to the previous version. You can check out the repo here 👉 https://lnkd.in/eaF9nWST Feel free to open issues for suggestions, ideas, or anything you find useful! And if you want to try it yourself: ``` pip install pytest-forger ``` Let's keep building! #Python #Tests #OpenSource #Development #PyTest

What's the first thing you do when you start a new project? For me, it's the CLI. A simple task runner to automate the repetitive stuff from day one — package installs, linters, builds, environment setup. Especially now that projects are often multi-language, where we're juggling python, node, and shell scripts in the same repo. A CLI keeps that manageable before it gets out of control. ... and probably the most important benefit: I get to type less!

Security API for RACF 0.6.0 just released and delivers generic checking for resource and dataset profiles. It also comes with a more flexible Python build process if you want to build the Python version yourself. In addition to the new features it also comes with a ton of bug fixes. pySEAR can be acquired here: https://lnkd.in/dtvsu_Tt The repository can be viewed here: https://lnkd.in/dXRRv2Vu Documentation here: https://lnkd.in/eAcBtx_J Thanks to everyone who contributed, whether it be bug reports or code.

🚀 Behind Every Login System → Sessions Worked on implementing session management using Flask to understand how applications remember users across requests. Three steps: • Session creation • Secure cookie-based storage • Accessing session data across routes A small concept, but a core building block of modern web applications. #Python #FlaskFramework #BackendDeveloper #WebSecurity
