React Props Enable Data Flow and Component Reusability

·1 views

Props, short for properties, are a core mechanism for passing data between components in a React application. They allow a parent component to send read-only information to its child components. This makes components reusable, as a single component like 'Student' can display different data based on the props it receives. A key rule is that child components must not modify the props they are given.

Hidden Database Secret Exfiltrated Through Search Bar SQL Injection

A security write-up details a SQL injection vulnerability in a web application's product search feature. The vulnerability occurs because user input is directly embedded into a raw SQL query without any sanitization. An attacker can use a UNION SELECT attack to extract data from database tables unrelated to the product catalogue, such as user credentials. The article explains that the final objective is to retrieve a specific secret from a table named 'internal_secrets', which is not accessible through normal search results.

Open-source desktop dictionary editor released for Loglan constructed language

Developers have created LOD Manager, an open-source desktop application for editing the Loglan Online Dictionary. The tool replaces legacy text files with a modern SQLite-backed interface for the language created in the 1950s. Built with Tauri v2, Svelte 5, and Rust, it operates offline-first with no cloud dependency or telemetry. The application preserves Loglan as a structured, machine-readable corpus for linguistic research and community use.

Security analysis flags flash loan vulnerabilities in high-value DeFi protocol Bitkub

A security analysis dated October 2026 examines flash loan attack vectors for the Bitkub DeFi protocol, which holds over $1.5 billion in assets. The report identifies several potential vulnerabilities, including price oracle manipulation and reward distribution issues, due to the protocol's reliance on external data feeds. These weaknesses could allow attackers to borrow large sums, manipulate on-chain state within a single transaction, and extract value. The analysis concludes Bitkub's high value and system design present a non-trivial attack surface, giving it an overall flash loan risk score of 8 out of 10.

TokenCap tool creates secure local bridge to feed code context to browser AI chats

Developers have created a tool called TokenCap to securely provide AI chatbots like ChatGPT and Claude with local repository context. The system consists of a local HTTP daemon that runs strictly on a loopback interface and a browser extension companion. A pairing token and origin allowlists ensure only approved local connections can access the bridge while keeping the system isolated from public networks. The daemon pre-warms repository snapshots in memory to enable instant context injection when requested. This allows developers to inject structured code context directly into AI chat prompts without manual file uploads or copy-pasting.
