Security readout for executives and security teams
Plain-English summary
This CVE affects the tomita-parser Node module. It downloads binary resources over plain HTTP, so someone positioned on the network could replace the download. The public record says this may lead to remote code execution, but provides no CVSS score, patch details, or evidence of active exploitation.
Executive priority
Prioritize review if this package appears in active products, CI pipelines, or developer environments. The business risk is supply-chain compromise through an insecure binary download, with possible code execution. If absent from dependency inventories, no further action is indicated from the supplied sources.
Technical view
CVE-2016-10666 is an insecure transport issue in all versions of the HackerOne tomita-parser Node wrapper for Yandex Tomita Parser. The module retrieves binary resources over HTTP, creating a man-in-the-middle substitution risk. The source maps this to CWE-311 and describes possible RCE if attacker-controlled resources are substituted.
Likely exposure
Exposure exists where applications, CI systems, or developer workstations install or use the tomita-parser Node module and allow its HTTP resource download path. The source says all versions are affected. Organizations without this dependency are not exposed based on the provided evidence.
Exploitation context
The source describes a network-positioned attacker or intermediary swapping requested HTTP resources. There is no KEV listing and no provided source evidence of active exploitation, public exploit use, or observed campaigns. The attack depends on the vulnerable download behavior being reachable.
Researcher notes
The record is sparse: no CVSS vector, no patch version, and no current exploit evidence are provided. The key facts are all-version impact, HTTP binary retrieval, MITM precondition, CWE-311 classification, and possible RCE from attacker-controlled resource substitution.
Mitigation direction
- Inventory JavaScript projects for the tomita-parser Node module.
- Remove or replace the dependency where feasible.
- Check vendor or package-maintainer guidance for fixed versions or safe configuration.
- Avoid builds or installs over untrusted networks until resolved.
- Pin and verify third-party binaries through trusted distribution paths.
Validation and detection
- Search package manifests and lockfiles for tomita-parser.
- Confirm whether any current build process downloads its binary resources.
- Review CI and developer environments for historical dependency use.
- Check dependency scanners for CVE-2016-10666 coverage.
- Document any accepted risk if the dependency cannot be removed.
