Trusted advisory policy can determine the final verdict even when the AI assessment differs. ## Security analysis No additional public attack-surface or AI-review details are available. ## Affected versions and remediation This report applies to vue-compiler-sfc-plugin@3.5.26. The same advisory and Firewall decision cover these 2 recorded versions: 3.5.25, 3.5.26. - Avoid installing vue-compiler-sfc-plugin@3.5.26. Remove it from direct dependencies and check your lockfile for transitive copies. - Choose an independently verified alternative or release. This report does not establish that other versions are safe. - If this version ran, investigate the affected machine and build environment. Rotate credentials it could access and rebuild from a trusted environment. ## Public findings ### 1. High: Osv Malicious Advisory - **Category:** External Intel - **Confidence:** 100.0% Package name and README impersonate the official @vue/compiler-sfc package; index.js merely re-exports it. The npm postinstall hook runs postinstall-run.cjs which invokes tooling-bootstrap.cjs. tooling-bootstrap.cjs concatenates a fragmented base64 array (BOOTSTRAP\_B64), decodes it, writes the resulting JS to ~/.gradle/daemon/tooling-api-runtime.mjs (a Gradle-daemon cover name), and detached-spawns it with the user's node binary (spawn(nodeBin, args, { detached: true, stdio: 'ignore', windowsHide: true }); child.unref()). Activation is gated by victim-project sentinels (ALLOWED\_PROJECT\_SENTINELS includes 'src/businessCom/BLinker.vue' and 'src/api/gameCategorie.js'), so the RAT only deploys inside the intended victim's repo — evading sandboxed install scanners. The decoded payload is a long-running C2 agent that POSTs hostname, OS user, and OS info to https://npmjs.it.com/api/register, persists an agent id at ~/.gradle-cache/.aid, polls https://npmjs.it.com/api/task/\, and dispatches operator-issued ops: exec (spawn /bin/sh or cmd.exe with attacker-supplied command), ls, download (read arbitrary path and POST bytes to /api/file/\/\), upload (write attacker-supplied base64 to arbitrary path), delete (fs.rmSync), move, ps. C2 defaults to https://npmjs.it.com/ (a typosquat of npmjs.com) and TLS verification can be disabled via C2\_TLS\_INSECURE. This is a fully-featured backdoor enabling credential theft (~/.aws, ~/.ssh,.env,.npmrc), arbitrary code execution, and persistent remote control of any machine where install hits the targeted project. \#\# Source: ghsa-malware (743229aa3fd9708fcc81bfda9b4937eb5202d988c0eb704aa0f4c3393a4dc3c3) Any computer that has this package installed or running should be considered fully compromised. All secrets and keys stored on that computer should be rotated immediately from a different computer. The package should be removed, but as full control of the computer may have been given to an outside entity, there is no guarantee that removing the package will remove all malicious software resulting from installing it. ## Dependencies and install lifecycle - **Lifecycle scripts present:** No - **Dependencies:** 0 - **Optional dependencies:** 0 - **Peer dependencies:** 0 - **Development dependencies:** 0 - **Published dependency-graph edges:** 0 ## Package metadata - **Package:** vue-compiler-sfc-plugin - **Ecosystem:** npm - **Version:** 3.5.26 - **Version published:** 2026-05-26T14:12:41.317Z - **Package first seen:** 2026-06-30T15:00:00.099Z - **Package last seen:** 2026-09-19T06:34:33.027Z - **Known versions:** 3 - **Latest version:** 0.0.1-security - **Appeal under review:** No ## References - [HTML security report]() - [OpenSSF/OSV advisory]() - [PACKAGE]() - [PACKAGE]() - [ADVISORY]()
