The Eclipse Foundation has implemented mandatory pre-publish security checks for all open VSX extensions to combat supply chain threats and malicious activity, marking a significant shift toward a proactive approach in securing the Open VSX Registry.
The Eclipse Foundation has implemented mandatory pre-publish security checks for all open VSX extensions to combat supply chain threats and malicious activity. The new approach aims to reduce the window of exposure by flagging suspicious uploads for review instead of publishing them immediately. The move is a significant shift toward a proactive approach in securing the Open VSX Registry, marking a departure from traditional reactive methods. The pre-publish checks will focus on identifying cases of extension name or namespace impersonation, accidental published credentials or secrets, and known malicious patterns. The goal is to raise the security floor, help publishers catch issues early, and keep the experience predictable and fair for good-faith publishers.
The recent announcement by the Eclipse Foundation, a prominent organization that maintains the Open VSX Registry, has sent shockwaves through the open-source community. In an effort to combat the rising tide of supply chain threats and malicious extensions, the foundation has implemented mandatory pre-publish security checks for all open VSX extensions. This proactive approach marks a significant shift from the traditional reactive methods, where only after-the-fact response and investigation were employed.
As Christopher Guindon, director of software development at the Eclipse Foundation, aptly put it, "Up to now, the Open VSX Registry has relied primarily on post-publication response and investigation. When a bad extension is reported, we investigate and remove it." While this approach remains relevant and necessary, it does not scale as publication volume increases and threat models evolve. The new pre-publish checks aim to limit the window of exposure, flagging suspicious uploads for review instead of publishing them immediately.
The need for such a proactive measure has become increasingly evident in recent times. Open-source package registries and extension marketplaces have become hotbeds for malicious activity, allowing attackers to target developers at scale through various tactics like namespace impersonation and typosquatting. A recent incident involving Socket, where a compromised publisher's account was used to push poisoned updates, highlights the urgency of this issue.
Microsoft has already taken steps in this direction, implementing a multi-step vetting process for its Visual Studio Marketplace. This includes scanning incoming packages for malware, then rescanning every newly published package "shortly" after it's been published, and periodic bulk rescanning of all packages. The Eclipse Foundation is now extending this effort to ensure the Open VSX Registry aligns with these security standards.
The pre-publish checks will focus on identifying clear cases of extension name or namespace impersonation, accidentally published credentials or secrets, and known malicious patterns. These scenarios will trigger quarantining of suspicious uploads for review by maintainers before publication. The implementation is expected to be rolled out in a staged fashion, with the maintainers using February 2026 as a monitoring period without blocking publication.
Guindon emphasized that the goal and intent behind this move are to raise the security floor, help publishers catch issues early, and keep the experience predictable and fair for good-faith publishers. By pre-publish checks, the likelihood of obviously malicious or unsafe extensions entering the ecosystem decreases, which in turn increases confidence in the Open VSX Registry as shared infrastructure.
The threat landscape continues to evolve with new vulnerabilities and exploits emerging regularly. The need for proactive security measures like these pre-publish checks becomes increasingly important. As Guindon said, "Pre-publish checks reduce the likelihood that obviously malicious or unsafe extensions make it into the ecosystem, which increases confidence in the Open VSX Registry as shared infrastructure."
The Eclipse Foundation's move toward mandatory pre-publish security checks for open VSX extensions represents a significant step forward in securing the open-source community. By embracing this proactive approach, developers and maintainers can enjoy a more secure environment, knowing that their extensions are thoroughly vetted before they reach users.
