This creates install-time remote code execution as the installing user. - **Trigger:** npm installation on a host where bun is not already available - **Impact:** Remote content from bun.sh can execute with the installer’s user privileges. - **Evidence paths:** package.json, scripts/install-bun.mjs, dist/tools/shared.js, dist/security/index.js - **Review source:** ai\_review - **Reviewed:** 2026-08-17T04:19:49.244Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** postinstall curl/PowerShell download piped to a shell - **Attack narrative:** During npm installation, package.json invokes scripts/install-bun.mjs. If \`bun --version\` fails, the script fetches Bun’s installer from bun.sh and pipes it into bash, or executes a remote PowerShell expression on Windows. The package does this without an explicit user command or integrity-pinned payload, allowing the remote endpoint’s current response to run as the installing user. - **Rationale:** The package’s main functionality and runtime security controls appear package-aligned, but the unconditional postinstall remote-script execution is a concrete, unconsented install-time RCE path. - **Files touched:** scripts/install-bun.mjs - **Network endpoints:** https://bun.sh/install, https://bun.sh/install.ps1 ### Review decision - **Verdict:** Malicious - **Confidence:** 94.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** npm postinstall automatically runs scripts/install-bun.mjs., When Bun is absent, that script pipes a remote bun.sh response directly into bash., The remote installer runs with the installing user’s environment and privileges. - **Evidence against:** No separate credential-exfiltration or stealth persistence path was found in inspected code., Runtime agent command execution is paired with secret-filtered child environments and workspace security controls. ## Public findings ### 1.
