📰 Researchers Demonstrate Node2Shell RCE Exploit on Node.js Build Using Crafted Brotli Data

Malicious Brotli data can make an application on an official build of Node.js run attacker-supplied code, security researchers at Imperva have demonstrated.Their "Node2Shell" proof of concept ran code on the official Node.js 24.22.0 image for Linux arm64, with no debugger or custom build, by feeding crafted data to the bundled Brotli decoder (CVE-2026-111497). Node.js disclosed the flaw.

‍Ubuntu firmware HWE will prevent issues on older kernel

Ubuntu is planning a new linux-firmware-hwe package, in an effort to reduce the risk of firmware updates for newer kernels causing problems for users running older ones. On Ubuntu long-term support (LTS) releases, you can stick with the standard (GA) kernel it was released with for the duration of its support period, or you can install the HWE update, which brings newer Linux kernel versions to existing Ubuntu LTS releases.  Right now, both kernels share the same firmware package, which means firmware updates designed to work with HWE kernels can cause problems for users who stick with the GA kernel. Ubuntu developer Juerg Haefliger noted that a firmware backport for Ubuntu 24.04 LTS, intended for its Linux 7.0 […]

📰 Critical Flaw in Python’s Popular Pillow Image Library Allows Code Execution via a Crafted Image

Pillow, the most widely used image library for Python, can be made to run operating system commands on a server by specifying the name of a file it is told to open.The flaw, CVE-2026-112900, is in the way Pillow handles EPS images, which it opens by passing the file's name to Ghostscript, a separate program it runs to turn the image into pixels, without checking the name first.

Replace SharePoint tempauth URLs with Entra ID tokens

On April 1, 2027, SharePoint Online and OneDrive will stop returning pre-authenticated URLs from Microsoft Graph, the REST API for Microsoft 365 data, for common file operations. Today those links carry a short-lived SharePoint credential in the tempauth query string, so a follow-up download or upload works without a token in an Authorization header. After the change, apps must send a Microsoft Entra ID access token in that header instead. Many flows then need two tokens: one for Graph and one for your SharePoint tenant host. A tenant setting can route some apps to Graph URLs so they stay on the Graph token only.
