CVE-2025-1974 is a critical remote code execution (RCE) vulnerability in Kubernetes’ Ingress-NGINX Controller that allows unauthenticated attackers with network access to inject arbitrary NGINX configuration directives, potentially leading to full cluster compromise. Ingress-NGINX is a software-only ingress controller provided by the Kubernetes project. Because of its versatility and ease of use, ingress-nginx is quite popular: it is deployed in over 40% of Kubernetes clusters.

The terms “patch management” and “vulnerability management“ are not the same. And that difference is a big difference. They may be confused because applying patches is one of the many ways to mitigate cyber risks. However, it is one piece of the entire vulnerability management puzzle and organizations that do not realize this are burdened with a false sense of security.

On March 24, 2025, ingress-nginx maintainers released fixes for multiple vulnerabilities that could allow threat actors to take over Kubernetes clusters. Ingress is a Kubernetes feature that defines how workload Pods are exposed to the network, while an Ingress Controller implements those rules by configuring the necessary local or cloud resources. According to Kubernetes, ingress-nginx is deployed in over 40% of Kubernetes clusters.

A major supply chain attack has exposed sensitive CI/CD secrets in GitHub Action tj-actions/changed-files, known as CVE-2025-30066, across 218 repositories. This incident has raised significant concerns about security and is connected to an earlier attack on the other GitHub Action, reviewdog/action-setup@v1, tracked as CVE-2025-30154. While only 4% of the 5,416 repositories that were affected had secrets leaked, the damage is severe.

Data poisoning is a sophisticated adversarial attack designed to manipulate the information used in training artificial intelligence (AI) models. By injecting deceptive or corrupt data, attackers can hurt model performance, introduce biases, or even create security vulnerabilities. As AI models increasingly power critical applications in cybersecurity, healthcare, finance, and many other industries, maintaining the integrity of their training data is absolutely critical.

On March 24, 2025, Wiz Research disclosed a series of critical vulnerabilities in Ingress NGINX Controller for Kubernetes, collectively dubbed: These unauthenticated Remote Code Execution (RCE) vulnerabilities have been assigned a CVSS base score of 9.8. According to Wiz Research, exploitation allows attackers to gain unauthorized access to all secrets across all namespaces in affected Kubernetes clusters, potentially leading to complete cluster takeover.

On Monday, March 24, 2025, a set of critical vulnerabilities affecting the admission controller component of the Ingress NGINX Controller for Kubernetes was announced. In total, five vulnerabilities were announced; the most severe vulnerability, CVE-2025-1974 (CVS 9.8), may result in remote code execution (RCE). Exploitation of this vulnerability can be detected with Sysdig Secure or the Falco rule provided in this article.

On March 11, 2025, a supply chain attack targeting the widely used GitHub Action reviewdog/action-setup@v1, leading to the exposure of sensitive CI/CD secrets across multiple repositories. The attack was identified by Wiz Research, which determined that this compromise played a pivotal role in the tj-actions/changed-files incident (Wiz, 2025).
