A single malformed character in a web request can let an unauthenticated attacker slip past the access controls that guard applications built on Starlette, the open-source Python framework that powers FastAPI, researchers said.
The flaw, tracked as CVE-2026-48710 could allow attackers to bypass host-validation protections using malformed Host headers, according to an advisory from cybersecurity firm X41 D-Sec.
The attacker needs no password and no action from a victim, it said.
Starlette’s maintainer released a patch through an official GitHub security advisory after X41 D-Sec disclosed the vulnerability in coordination with the Open Source Technology Improvement Fund (OSTIF). They found the flaw during an unrelated source-code audit, and traced it to Starlette rather than the application under review.
“This bug is a classic ‘responsibility gap’ where if this maintainer didn’t patch, thousands of exposed projects would have to individually secure their projects,” OSTIF said.

In this article, we will dive deep into five must-know Python concepts that will help you transition from writing clunky, slow spaghetti code to constructing lightning-fast, production-grade, and beautifully functional data pipelines.
In the ever-evolving cybersecurity landscape, Microsoft has introduced various new features in Windows 11 designed to protect users from modern workplace threats. Among such features, Smart App Control (SAC) changes how Windows devices handle, and occasionally block, unwanted or potentially malicious applications.
But what exactly is Smart App Control? How does it work, who benefits most, and are there any caveats? In this story we’ll share some history and explain why SAC has been something of a stealth feature in Windows 11.
What is Smart App Control?
Smart App Control is a security feature in Windows 11 designed to block untrusted or potentially dangerous applications from running on a PC. Built directly into the operating system (through Windows Security), SAC leverages code signing, Microsoft’s intelligence cloud, and artificial intelligence to make real-time decisions about whether an app or application should be allowed to run. Its goal is to minimize the risk that malware, rans

AgentTrove is the largest open-source collection of agentic interaction traces, with 1.7M rows in a ShareGPT-style layout. This hands-on Python tutorial shows how to stream the dataset without full downloads, normalize agent turns, extract commands, analyze trajectories, and export successful traces into a clean SFT fine-tuning dataset.
