EchelonGraph scoreMEDIUM confidence

This high-severity CVE scores 8.2 under the CNA's CVSS (NVD's own analysis pending). EPSS exploit probability: 0.7%, top 49% of all CVEs by exploit prediction. GitHub Security Advisory data not yet ingested — confidence will rise once GHSA publishes (typical lag: hours to days for open-source ecosystem CVEs; never for infrastructure-only CVEs).

A fix is available — apply it.

Versions of the package dset before 3.1.4 are vulnerable to Prototype Pollution via the dset function due improper user input sanitization. This vulnerability allows the attacker to inject malicious object property using the built-in Object property __proto__, which is recursively assigned to all the objects in the program.
