Security readout for executives and security teams
Plain-English summary
The co-cli-installer npm package fetched the co-cli module over plain HTTP during installation. A network-positioned attacker could potentially replace that download with malicious content, turning a normal install into code execution. The source bundle does not provide CVSS, a patch version, or evidence of active exploitation.
Executive priority
Prioritize review if this package appears in build pipelines or developer tooling. The business risk is supply-chain compromise during installation, not a confirmed internet-exposed runtime flaw. Urgency depends on whether the module is still used and where installs occur.
Technical view
CVE-2016-10657 affects all versions of the co-cli-installer node module. The install workflow downloads co-cli over HTTP, exposing the transfer to man-in-the-middle tampering. If the downloaded resource is swapped by an attacker on the network path, installation may execute attacker-controlled code. The weakness is mapped to CWE-311.
Likely exposure
Exposure is likely limited to environments that install or rebuild dependencies containing co-cli-installer, especially CI, developer workstations, or build systems using untrusted networks. Runtime exposure after installation is not established by the provided sources.
Exploitation context
The described attack requires an attacker positioned on the victim's network path or between the user and the remote server during installation. The bundle says KEV is false and provides no cited evidence of active exploitation.
Researcher notes
Evidence is sparse: the CVE record identifies all versions of one npm module and an HTTP download during install. No CVSS vector, exploit report, fixed version, or patch details are included in the provided bundle. Avoid assuming broader package impact without dependency evidence.
Mitigation direction
- Inventory dependencies for co-cli-installer and any transitive usage.
- Check the Node Security advisory and vendor guidance for current remediation.
- Avoid installing affected packages on untrusted or interceptable networks.
- Remove or replace the dependency where business use is not required.
- Treat builds using this package as higher risk until reviewed.
Validation and detection
- Search package manifests and lockfiles for co-cli-installer.
- Review CI build logs for installs involving the affected module.
- Confirm whether developer workstations or build runners installed it.
- Verify dependency provenance for artifacts built from affected environments.
- Check whether any vendor remediation exists before approving continued use.
