Over the past few weeks, the Open VSX team and the Eclipse Foundation have been responding to reports of leaked tokens and related malicious activity involving certain extensions hosted on the Open VSX Registry.
A vulnerability in the Eclipse Open VSX Registry’s automated publishing system could have allowed unauthorized extension uploads. It did not affect existing extensions or admin functions.
The issue was reported on May 4, 2025, fully fixed by June 24, and followed by a complete audit. No evidence of compromise was found, but 81 extensions were proactively deactivated as a precaution.
