  • @qlik/eslint-config-svelte

A malware-containing version of the npm package @qlik/eslint-config-svelte was published and made available to users. The GitHub Security Advisory (GHSA-f6jv-v6m4-m7h4) indicates that any computer with this package installed or running should be considered fully compromised.\n\nThe advisory recommends that all secrets and keys stored on affected computers be rotated immediately from a different, uncompromised system. While the malicious package should be removed, the advisory notes that full control of the computer may have been given to an outside entity, meaning removal of the package alone may not eliminate all malicious software that resulted from the installation.\n\nThis is a critical supply chain incident affecting the npm ecosystem, with the attack vector being a compromised package distributed through the official npm registry.
