Eclipse Foundation's 2025 Response to Unauthorized Extension Uploads
In May 2025, the Eclipse Foundation identified a vulnerability in the Open VSX Registry's automated publishing system, potentially allowing unauthorized extension uploads. The flaw, reported by Koi Security researchers, involved inadequate isolation in build scripts, exposing a privileged token that could be exploited to publish extensions under any namespace. The issue was promptly addressed, with a fix deployed by June 24, 2025, and a comprehensive audit confirming no evidence of exploitation. As a precaution, 81 extensions were deactivated. This incident underscores the critical importance of securing automated processes in software supply chains to prevent unauthorized access and maintain trust in open-source ecosystems. The Eclipse Foundation has since implemented enhanced security measures, including sandboxing build processes and enforcing stricter credential management, to mitigate similar risks in the future.
