The Linux kernel is constantly evolving, and one of the significant additions in recent years is io_uring. Introduced in kernel 5.1 (2019), it’s designed to dramatically speed up input/output (I/O) operations. But as with many powerful tools, it brings new security considerations. Let’s break down what io_uring is, the risks it presents, and how to […]

Modern AI systems, especially large language models (LLMs), are no longer isolated engines responding to static inputs. They’re evolving into intelligent agents, copilots, and autonomous systems that interact with their environment, reason over external data, and adapt in real time. But there’s a fundamental problem: LLMs are powerful, but they don’t know anything outside of […]

On April 16, 2025, a critical remote code execution (RCE) vulnerability in Erlang’s SSH library was publicly disclosed. Tracked as CVE-2025-32433, this vulnerability received the maximum possible CVSS score of 10.0, signaling how severe and exploitable it is, especially in environments relying on Erlang/OTP for SSH access. Overview What is CVE-2025-32433? Discovered by researchers at […]

Kubernetes administrators take note: a critical set of vulnerabilities in the popular ingress-nginx controller—collectively dubbed “IngressNightmare”—could put your entire cluster at risk. In particular, CVE-2025-1974, with a CVSS score of 9.8, allows attackers to take over Kubernetes clusters simply by exploiting the Validating Admission Controller feature. Because ingress-nginx runs in roughly 40% of Kubernetes deployments, […]

Next.js middleware plays a key role in securing applications by enforcing authentication, managing access control, and applying security headers. However, a newly discovered vulnerability, CVE-2025-29927, allows attackers to bypass these protections entirely using a manipulated HTTP header. Affected Versions This flaw affects the following versions: The Core Issue Next.js prevents infinite middleware loops by tracking […]

A critical security vulnerability, identified as CVE-2025-24813, has been discovered in Apache Tomcat, potentially exposing servers to remote code execution (RCE), information disclosure, and data corruption risks. This flaw affects the following versions:​ Understanding CVE-2025-24813 The vulnerability originates from improper handling of path equivalence when processing filenames that contain internal dots. Specifically, when Tomcat’s default […]

Upwind’s Head of Security Research Moshiko Hassan, MDR Lead Omer Idel, and Head of Marketing Denise Ashur discuss the GitHub Actions supply chain compromise, including how widespread it is and what users should do to mitigate.

We are actively responding to a significant security breach involving the widely used GitHub Action, tj-actions/changed-files. Current findings indicate that nearly all tagged versions of tj-actions/changed-files have been compromised, resulting in direct access to running containers and virtual machines’ memory, allowing the extraction of sensitive secrets, information, and code. This is happening through the following command […]

A critical Remote Code Execution (RCE) vulnerability was recently discovered in python-json-logger, a widely used Python package for structured logging. This flaw, affecting versions 3.2.0 and 3.2.1, arises due to a missing dependency: msgspec-python313-pre. The package was deleted from PyPI, leaving its name unclaimed. This vulnerability highlights a recurring yet dangerous issue in software supply […]

On February 18, 2025, two critical vulnerabilities were disclosed in OpenSSH, a widely used secure networking utility suite. These flaws, identified as CVE-2025-26465 and CVE-2025-26466, pose significant security risks: Discovery and Response The vulnerabilities were uncovered by the Qualys Threat Research Unit (TRU). They affect OpenSSH client versions 6.8p1 through 9.9p1 and 9.5p1 through 9.9p1, […]
