Helm Dependency Update Vulnerability: Crafted Chart.yaml Can Lead to Local Code Execution

2025-07-09

Helm Dependency Update Vulnerability: Crafted Chart.yaml Can Lead to Local Code Execution

A vulnerability in Helm allows for local code execution through a carefully crafted Chart.yaml file and a symlinked Chart.lock file during dependency updates. Fields from Chart.yaml are written to Chart.lock during updates. If Chart.lock is symlinked to an executable file (e.g., bash.rc), updating dependencies writes the Chart.lock content to the symlinked file, leading to arbitrary code execution. Helm v3.18.4 patches this; upgrade and check for symlinked Chart.lock files.

tinymcp: Control Embedded Devices with LLMs

The tinymcp project enables Large Language Models (LLMs) to control embedded devices via the Model Context Protocol (MCP). It leverages Golioth's LightDB state and Remote Procedure Calls (RPCs) to achieve this. Existing devices can expose RPCs without firmware modification by updating LightDB state. A simple blinky example demonstrates exposing LED control to an LLM via tinymcp. Users need to connect a device to the Golioth platform and run the tinymcp server locally. Tools like MCP Inspector and Claude Code are available for testing and interaction with tinymcp.

Fine-tuning GPT-2 for Positive Sentiment Generation using RLHF

Fine-tuning GPT-2 for Positive Sentiment Generation using RLHF

This project provides a reference implementation for fine-tuning a pretrained GPT-2 model to generate sentences expressing positive sentiment using Reinforcement Learning from Human Feedback (RLHF). The process involves three steps: 1. Supervised Fine-Tuning (SFT): Fine-tuning GPT-2 on the stanfordnlp/sst2 dataset; 2. Reward Model Training: Training a GPT-2 model with a reward head to predict sentiment; 3. Reinforcement Learning via Proximal Policy Optimization (PPO): Optimizing the SFT model to generate sentences that the reward model evaluates positively. These three steps are implemented in three Jupyter Notebooks, allowing for a step-by-step approach. A Hugging Face access token is required to download the pretrained GPT-2 model.
