Open VSX Bug Let Malicious VS Code Extensions Bypass Pre-Publish Security Checks
A logic flaw in Open VSX's security scanning allowed malicious VS Code extensions to bypass checks and reach users.
Cybersecurity researchers have disclosed details of a now-patched bug impacting Open VSX's pre-publish scanning pipeline that allowed a malicious Microsoft Visual Studio Code extension to pass the vetting process and go live in the registry. The pipeline had a single boolean return value that meant both 'no scanners are configured' and 'all scanners failed to run.' The vulnerability has been fixed.

SENTINEL: This means regular developers and hobby coders using VS Code could easily pick up harmful extensions that look legitimate, putting their work and personal data at risk without any obvious warning. It shows how one tiny mistake in a security tool can quietly weaken trust in the everyday software we all rely on.
