Security readout for executives and security teams
Plain-English summary
This CVE affects the merge-objects Node.js module. If an attacker can control part of data passed into its utility function, they may alter Object’s prototype, causing attacker-chosen properties to appear on all objects in the process.
Executive priority
Treat as a dependency exposure review item, not an emergency based on current evidence. Prioritize internet-facing services and systems processing user-submitted JSON or object-like data.
Technical view
All merge-objects versions <= 1.0.0 are described as vulnerable to prototype pollution through attacker-controlled object structure passed to a utilities function. The bundle provides no CVSS, CWE, affected CPEs, or named fixed version.
Likely exposure
Exposure is likely limited to Node.js applications that depend on merge-objects <= 1.0.0 and pass untrusted structured input into the affected utility path.
Exploitation context
The source bundle does not show CISA KEV status or any cited evidence of active exploitation. Practical impact depends on reachable input paths and how polluted object properties influence application logic.
Researcher notes
Evidence is sparse: the bundle gives the vulnerability mechanism and affected version range, but no CVSS, CWE, patch version, exploit status, or downstream product impact. Avoid claiming active exploitation without additional sources.
Mitigation direction
- Inventory Node.js projects for merge-objects versions <= 1.0.0.
- Check package or vendor guidance for a fixed version or replacement.
- Do not pass untrusted object structures into affected merge utilities.
- Validate structured input before merge operations.
- Review dependent packages that may include merge-objects transitively.
Validation and detection
- Search dependency manifests and lockfiles for merge-objects.
- Confirm deployed builds do not include versions <= 1.0.0.
- Trace whether user-controlled data reaches merge-objects utilities.
- Review tests for prototype pollution regression coverage.
- Check runtime behavior for unexpected inherited object properties.
