Errors are hidden unless an environment flag is set. - **Trigger:** Runtime import/require of chai-plus - **Impact:** Executes attacker-selected third-party package code and initiates its remote-configured setup outside the caller's requested assertion-library function. - **Evidence paths:** package.json, lib/index.js, lib/bootstrap.js, lib/snapshot.js - **Review source:** ai\_review - **Reviewed:** 2026-08-25T16:51:12.782Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** import-time global package installation and command execution - **Attack narrative:** A consumer imports the declared main entrypoint. Its immediately invoked bootstrap constructs defaults for taskforge-9xv, runs npm list -g, installs taskforge-9xv@1.3.0 globally if absent, and executes its binary with a remote origin-server argument. This unrelated command execution is concealed by catch logic that normally suppresses bootstrap failures. - **Rationale:** The package's import-time side effect is unrelated to its advertised assertion API and silently installs and executes another package with remote configuration. This is a concrete malicious execution chain, not an explicit user setup action. - **Files touched:** lib/index.js, lib/bootstrap.js - **Network endpoints:** http://coolblast.zapto.org:8888/api/x-handler ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** Importing the main entrypoint automatically invokes Bootstrap and suppresses failures., Bootstrap defaults to an unrelated global package and passes a remote origin URL plus auth reference., The bootstrap flow globally installs that package, then executes its command with those setup arguments., Manifest declares no install lifecycle hook; the behavior instead activates at import time. - **Evidence against:** No additional network, credential-harvesting, eval, or native-loading primitive was found in the shipped library files., Snapshot filesystem writes are user-invoked testing functionality scoped to \_\_snapshots\_\_. ## Public findings ### 1. Low: Scripts Present - **Category:** Manifest - **Confidence:** 100.0% Package declares npm scripts. ### 2. Medium: Environment Vars - **Category:** Source - **Confidence:** 75.0% Package source references environment variables. ### 3. Low: Filesystem - **Category:** Source - **Confidence:** 70.0% Package source references filesystem APIs. ### 4. Low: Url Strings - **Category:** Supply Chain - **Confidence:** 65.0% Package source contains URL literals. ### 5. High: Ai Review Evidence - **Category:** Ai Review - **Confidence:** 99.0% Importing the main entrypoint automatically invokes Bootstrap and suppresses failures. ### 6. High: Ai Review Evidence - **Category:** Ai Review - **Confidence:** 99.0% Bootstrap defaults to an unrelated global package and passes a remote origin URL plus auth reference. ### 7. High: Ai Review Evidence - **Category:** Ai Review - **Confidence:** 99.0% The bootstrap flow globally installs that package, then executes its command with those setup arguments. ### 8. High: Suspicious Lifecycle Evidence - **Category:** Manifest - **Confidence:** 99.0% Manifest declares no install lifecycle hook; the behavior instead activates at import time. ## Dependencies and install lifecycle - **Lifecycle scripts present:** Yes - **Published lifecycle scripts:** prepublish - **Dependencies:** 0 - **Optional dependencies:** 0 - **Peer dependencies:** 0 - **Development dependencies:** 0 - **Published dependency-graph edges:** 0 ## Package metadata - **Package:** chai-plus - **Ecosystem:** npm - **Version:** 6.2.3 - **License:** MIT - **Version published:** 2026-08-25T13:30:23.595Z - **Package first seen:** 2026-08-25T16:51:01.085Z - **Package last seen:** 2026-08-26T17:33:58.176Z - **Known versions:** 5 - **Latest version:** 0.0.1-security - **Appeal under review:** No - **Description:** Chai Plus - Extended assertion and testing library with zero dependencies. 50+ assertions, mock/spy, snapshots, benchmarking, and async support built on Chai concepts. - **Author:** Nakamoto Yoshiki - **Keywords:** assertion, testing, bdd, tdd, expect, assert, mock, spy, snapshot, async, promise, benchmark - **Runtime engines:** node: \>=12.0.0 - **Artifact files:** 14 - **Artifact unpacked size:** 69,032 bytes - **Artifact signatures:** 1 - **Attestations:** No ## References - [HTML security report]() - [OSV advisory]() - [PACKAGE]() - [PACKAGE]() - [PACKAGE]() - [ADVISORY]()
