Security readout for executives and security teams
Plain-English summary
This issue affects the scalajs-standalone-bin Node module. It downloads binaries over unencrypted HTTP, so a network-positioned attacker could replace the downloaded binary. If that substituted binary runs, sources say remote code execution may be possible. The provided sources do not name a fixed version or patch.
Executive priority
Prioritize environments where this package runs in CI, developer workstations, or production build pipelines. The business risk is supply-chain code execution through tampered binary downloads, but evidence of active exploitation is not provided.
Technical view
scalajs-standalone-bin downloads binary resources over HTTP. That exposes the download to man-in-the-middle tampering and binary substitution. The CVE description states RCE may be possible if an attacker is on the network or between the user and remote server. All versions are listed affected; CVSS and vendor fix details are not provided.
Likely exposure
Exposure is likely limited to systems that install or execute the scalajs-standalone-bin Node module, especially build or developer environments where binary downloads occur over networks susceptible to interception.
Exploitation context
The source bundle does not show active exploitation or KEV listing. Exploitation requires network positioning or control of traffic between the user and the remote server during the binary download.
Researcher notes
The evidence is sparse: CWE-311, all versions affected, HTTP binary download, possible RCE via MITM, and no CVSS details. No patch, exploit activity, or confirmed exploitation source is included in the bundle.
Mitigation direction
- Inventory projects for the scalajs-standalone-bin Node module.
- Avoid using affected builds that download binaries over HTTP.
- Check vendor or package-maintainer guidance for fixed versions or replacement packages.
- Use trusted build networks and artifact sources while remediation is pending.
- Review build artifacts created after affected package installation.
Validation and detection
- Check package manifests and lockfiles for scalajs-standalone-bin.
- Confirm whether installed versions match the affected all-versions statement.
- Review build logs for binary downloads over HTTP.
- Verify no unexpected binaries were introduced during affected installs.
- Document compensating controls if removal is not immediately possible.

Missing Encryption of Sensitive Data
Missing Encryption of Sensitive Data represents a recurring weakness pattern that can create exploitable paths when design, validation, or implementation controls are missing.
