Malicious code was inserted into the Nx (build system) package and several related plugins.
CVSS 9.6 Critical EPSS 0.6% · p46 Check exposure
Should you act?
Critical and remotely reachable
No known exploitation yet, but it is network-reachable without credentials. This signal is computed from CISA KEV, EPSS and CVSS data; it is not an editorial verdict.
- Not in CISA KEV, but CISA’s SSVC assessment records a public proof-of-concept, so attack code exists.
- EPSS 0.6%, percentile 46: FIRST’s model estimates a 0.6% chance of exploitation activity in the next 30 days, higher than 46% of all scored CVEs (low). EPSS is a probability, not a verdict.
- Needs a user to click or open something. Phishing makes that realistic, but it is not wormable.
- Editorial verdict: Check exposure. Nx s1ngularity: Malicious npm Releases Hijack AI CLIs — The packages were live for about four hours in August 2025, but anything they stole (GitHub and npm tokens, SSH keys, .env files, wallets) stays useful until rotated, so confirm you were not hit rather than assume.
What it is
Malicious code was inserted into the Nx (build system) package and several related plugins. The tampered package was published to the npm software registry, via a supply-chain attack. Affected versions contain code that scans the file system, collects credentials, and posts them to GitHub as a repo under user's accounts.
Weakness type: CWE-506.

CVSS measures how bad a flaw is if exploited, not how likely exploitation is. Read it next to the exploitation data below.
Exploitation and urgency
- CISA KEV: not listed (no confirmed in-the-wild exploitation known to CISA).
- CISA SSVC assessment: exploitation poc, automatable no, technical impact total.
- FIRST EPSS (model of 2026-10-21): 0.56% probability of exploitation activity in the next 30 days; percentile 46.
