--- _-= Per source details.

The package ships no real functionality — index.js only prints a proof-of-concept notice and README self-labels as a 'Responsible Disclosure' PoC. Regardless of the PoC framing, installers receive no benign function and their host identity is unconditionally beaconed to a non-publisher, non-registry endpoint on a default install. ## Source: ossf-package-analysis (8fd5381cd4364444dac8d64b33e317c526ef52948ebfb9d10e11ec0909b7d383) The OpenSSF Package Analysis project identified 'vue-demi-fix' @ 10.0.4 (npm) as malicious.
