This item details a newly discovered critical Linux kernel vulnerability, identified as CVE-2026-31431, also known as “Copy Fail.” The exploit allows an unprivileged local user to gain root privileges on affected Linux systems, including most major distributions. The ease of exploitation is particularly concerning, requiring only a small, 732-byte script and no complex race conditions. This vulnerability underscores the continuous need for vigilance in system patching and security updates, as it represents a straightforward path to complete system compromise from a local perspective. 本文详细介绍了一个新发现的关键 Linux 内核漏洞，编号为 CVE-2026-31431，也被称为“Copy Fail”。该漏洞允许非特权本地用户在受影响的 Linux 系统（包括大多数主流发行版）上获取 root 权限。其利用难度之低令人担忧，仅需一个 732 字节的小脚本，且无需复杂的竞争条件。该漏洞凸显了系统补丁和安全更新的持续必要性，因为它代表了一条从本地视角完全攻陷系统的直接途径。
Comment: As a developer, knowing a simple local bug can grant root access is a stark reminder to keep systems patched diligently, especially in shared or multi-user environments. 评论： 作为一名开发者，得知一个简单的本地漏洞就能获取 root 权限，这提醒我们必须勤于修补系统，特别是在共享或多用户环境中。
Official SAP npm packages compromised to steal credentials (r/cybersecurity)
SAP 官方 npm 包遭入侵，旨在窃取凭据 (r/cybersecurity)

This story reports a critical supply chain attack targeting official npm packages maintained by SAP. Adversaries successfully compromised these packages, injecting malicious code designed to steal user credentials. Such attacks highlight the severe risks associated with software supply chains, where compromise at one point can propagate to a vast number of downstream users. Organizations relying on open-source dependencies, especially those from major vendors, must implement robust security practices like integrity checks, dependency scanning, and least-privilege access for package maintenance to mitigate the threat of credential theft and broader system compromise. 本报道披露了一起针对 SAP 维护的官方 npm 包的关键供应链攻击。攻击者成功入侵了这些包，并植入了旨在窃取用户凭据的恶意代码。此类攻击凸显了软件供应链的严重风险，即单点受损可能波及大量下游用户。依赖开源组件（尤其是来自大型供应商的组件）的组织必须实施稳健的安全实践，如完整性检查、依赖扫描以及针对包维护的最小权限访问，以减轻凭据被盗和系统被全面攻陷的威胁。
Comment: This incident emphasizes that even “official” packages can be vectors for supply chain attacks; always verify integrity and consider locking down dependencies. 评论： 此事件强调了即使是“官方”包也可能成为供应链攻击的载体；请务必验证完整性，并考虑锁定依赖项。
How I got my homelab to a fully declarative state with Terraform + Komodo + Gitea + Infisical + PocketID — and had to build a missing piece myself (r/selfhosted)
如何通过 Terraform + Komodo + Gitea + Infisical + PocketID 将我的家庭实验室实现完全声明式管理，以及我不得不亲自补全缺失环节的经历 (r/selfhosted)

This article presents a practical guide on establishing a fully declarative homelab environment, with a strong focus on secure secrets management and identity. The author details an architecture leveraging tools like Terraform for infrastructure as code, Gitea for version control, and crucially, Infisical for secrets management and PocketID for identity. This setup provides a blueprint for maintaining sensitive data securely and automating access control in self-hosted environments. The emphasis on declarative configuration and dedicated secrets management tools offers a robust approach to hardening personal or small-scale infrastructure against common vulnerabilities. 本文提供了一份关于建立完全声明式家庭实验室环境的实用指南，重点关注安全的机密管理和身份验证。作者详细介绍了一种架构，利用 Terraform 进行基础设施即代码 (IaC) 管理，使用 Gitea 进行版本控制，并关键性地引入了 Infisical 进行机密管理，以及 PocketID 进行身份验证。该方案为在自托管环境中安全维护敏感数据和自动化访问控制提供了蓝图。对声明式配置和专用机密管理工具的强调，为加固个人或小型基础设施以抵御常见漏洞提供了一种稳健的方法。
Comment: Integrating Infisical and PocketID for secrets and identity in a declarative setup is a powerful move towards robust security; it simplifies management while bolstering defense in depth. 评论： 在声明式架构中集成 Infisical 和 PocketID 来处理机密和身份验证，是迈向稳健安全的重要一步；它在简化管理的同时，也加强了纵深防御。
