Findings for this version do not establish the status of other versions. AI assessment: suspicious; recommendation: downgrade to warn. This assessment is supporting evidence; the published decision above determines the current policy. This is a first-party CLI bootstrap action, but it occurs automatically at install time and delegates agent-skill mutation to an uninspected binary in the consumer project or global scope. No concrete exfiltration, destructive action, or payload chain is established from the inspected source. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 83.0% - **Started:** 2026-09-13T04:20:07.731Z - **Finished:** 2026-09-13T04:20:38.513Z - **Download time:** 766 ms - **Static scan time:** 22 ms - **AI review time:** 29993 ms - **Total time:** 30782 ms The recorded confidence comes from the underlying analysis. Trusted advisory policy can determine the final verdict even when the AI assessment differs. ## Security analysis ### Published attack-surface review - **Summary:** Installing the package automatically invokes an opaque platform binary to install Customer.io agent skills. In a project install it runs from the consumer project directory; global installs request global scope. - **Trigger:** npm postinstall during package installation - **Impact:** The uninspected platform binary may create or change agent-skill configuration in the selected project or global scope. - **Evidence paths:** package.json, .npm/postinstall.js - **Review source:** ai\_review - **Reviewed:** 2026-09-13T04:20:38.513Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** automatic invocation of a platform binary for agent-skill installation - **Rationale:** This is a first-party CLI bootstrap action, but it occurs automatically at install time and delegates agent-skill mutation to an uninspected binary in the consumer project or global scope. No concrete exfiltration, destructive action, or payload chain is established from the inspected source. - **Files touched:** package.json, .npm/postinstall.js ### Review decision - **Verdict:** Suspicious - **Confidence:** 83.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Low - **Evidence for warning:** The automatic postinstall hook runs a platform binary with the command \`cio skills install\`., For project installs, the hook changes its working directory to the consumer project through INIT\_CWD, allowing the invoked binary to modify project-level agent-skill locations. - **Evidence against:** The JavaScript launcher only resolves a declared platform-specific optional dependency and runs its cio binary., The inspected JavaScript contains no credential collection, network request, shell string execution, or self-dependency. ## Affected versions and remediation This report applies to @customerio/cli@0.0.27. - Review the evidence and your use of @customerio/cli@0.0.27 before allowing it. Restrict the permissions described in this report. - Choose an independently verified alternative or release. This report does not establish that other versions are safe. ## Public findings ### 1.

Medium: Ai Review Evidence - **Category:** Ai Review - **Confidence:** 83.0% - **Path:** .npm/postinstall.js - **Public source:** [View source]() For project installs, the hook changes its working directory to the consumer project through INIT\_CWD, allowing the invoked binary to modify project-level agent-skill locations. Public source snippet (untrusted): ```javascript const isGlobal = process.env.npm[redacted] === "true"; const scopeFlag = isGlobal ? "--global" : "--project"; const spawnOpts = { stdio: "inherit" }; // For project installs, npm runs postinstall with cwd inside node_modules. // INIT_CWD is the directory where the user ran npm install (the project root). if (!isGlobal && process.env.INIT_CWD) { spawnOpts.cwd = process.env.INIT_CWD; } ``` ## Dependencies and install lifecycle - **Lifecycle scripts present:** Yes - **Published lifecycle scripts:** postinstall - **Dependencies:** 0 - **Optional dependencies:** 6 - **Peer dependencies:** 0 - **Development dependencies:** 0 - **Published dependency-graph edges:** 6 ### Published dependency entries - @customerio/cli-darwin-arm64 0.0.27 (OptionalDependency) - @customerio/cli-darwin-x64 0.0.27 (OptionalDependency) - @customerio/cli-linux-arm64 0.0.27 (OptionalDependency) - @customerio/cli-linux-x64 0.0.27 (OptionalDependency) - @customerio/cli-win32-arm64 0.0.27 (OptionalDependency) - @customerio/cli-win32-x64 0.0.27 (OptionalDependency) ## Package metadata - **Package:** @customerio/cli - **Ecosystem:** npm - **Version:** 0.0.27 - **License:** SEE LICENSE IN LICENSE - **Version published:** 2026-09-08T06:03:20.301Z - **Package first seen:** 2026-07-03T00:00:52.435Z - **Package last seen:** 2026-10-14T09:53:00.837Z - **Known versions:** 11 - **Latest version:** 0.0.31 - **Appeal under review:** No - **Description:** Agent-first CLI for Customer.io APIs - **Maintainers:** ami-ci, ansible-runner - **Runtime engines:** node: \>=16 - **Artifact files:** 5 - **Artifact unpacked size:** 17,768 bytes - **Artifact signatures:** 1 - **Attestations:** Yes - **Provenance:** https://slsa.dev/provenance/v1 ## References - [HTML security report]() - [Repository]() - [Homepage]() - [Issues]()
