Multiple Node.js Modules compromised in self-spreading npm supply chain attack (mini-Shai-Hulud) (05/11/2026)

critical Nessus Plugin ID 315991

Language:

Synopsis

The remote host has a Node.js module compromised in the mini-Shai-Hulud supply chain attack installed.

Description

The remote host has a version of one or more Node.js modules installed known to be compromised in the self-spreading 'mini-Shai-Hulud' npm supply chain attack reported on 05/11/2026. This wave is tracked separately from the original Shai-Hulud campaign because of distinct compromised maintainers (TanStack, UiPath, DraftLab, Mistral, etc.), a different malware payload, and a different timeline.

A malicious update to these modules introduced credential harvesting that is then exfiltrated. It will then attempt to propagate to other packages that the maintainer controls.

The list of vulnerable Node.js packages this plugin checks for is up to date as of 05/11/26. However, the impact of this vulnerability is evolving and the list may become outdated if further vulnerable packages are discovered

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Update the affected node modules to a version higher than the known compromised versions.
