CRITICAL

setup.py executes code at install time

package/web/dist/assets/index-DBqU4k1C.js:13

* @license MIT
**/function _r(e,t,n,a){try{return a?e(...a):e()}catch(i){oo(i,t,n)}}function Zn(e,t,n,a){if(Mt(e)){const i=_r(e,t,n,a);return i&&rE(i)&&i.catch(r=>{oo(r,t,n)}),i}if(yt(e)){const i=[];for(let r=0;r<e.length;r++)i.push(Zn(e[r],t,n,a));return i}}function oo(e,t,n,a=!0){const i=t?t.vnode:null,{errorHandler:r,throwUnhandledErrorInProduction:l}=t&&t.appContext.config||cn;if(t){let o=t.parent;const c=t.proxy,d=`https://vuejs.org/error-reference/#runtime-${n}`;for(;o;){const _=o.ec;if(_)

Why was this flagged?

This setup.py calls subprocess, os.system, exec, or eval during package installation. Legitimate packages rarely need to execute arbitrary commands at install time. This pattern is commonly used by malicious packages to download and run payloads, exfiltrate environment variables, or establish persistence. Rated CRITICAL because it runs with the installer's full permissions.

Makefile/script pipes remote content to shell

package/web/dist/assets/index-DBqU4k1C.js:78

`,1;if(fn>1e5&&fn>tt.index*3)throw new Error("potential infinite loop, way more iterations than matches");return mt+=Ot,Ot.length}const Ct=pt(J);if(!Ct)throw X(Pt.replace("{}",J)),new Error('Unknown language: "'+J+'"');const sn=on(Ct);let Gt="",Ze=K||sn;const tn={},It=new Pe.__emitter(Pe);Bt();let mt="",dn=0,Jt=0,fn=0,ya=!1;try{if(Ct.__emitTokens)Ct.__emitTokens(ue,It);else{for(Ze.matcher.considerAll();;){fn++,ya?ya=!1:Ze.matcher.considerAll(),Ze.matcher.lastIndex=Jt;const Ye=Ze.matcher.exec(ue)

Why was this flagged?

A script or Makefile pipes content from a remote URL directly into a shell (curl | sh or wget | bash). This is inherently dangerous because the remote content can change at any time, and the command runs with the current user's permissions. Rated HIGH because it requires manual execution (unlike install hooks) but still executes arbitrary remote code.
