EchelonGraph scoreMEDIUM confidence

This medium-severity CVE scores 5.3 under a secondary CVSS source (NVD's own analysis pending). EPSS exploit probability: 0.3%, top 78% 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).

In Eclipse Ditto versions 3.0.0 to 3.9.6, the Things service fetches WoT (Web of Things) ThingModels over HTTP from URLs supplied by API users in the definition field of a Thing or Feature, without validating the target host, and follows HTTP redirects without re-validating the redirect target and without a hop limit. An authenticated user who is permitted to create a Thing, or who holds WRITE permission on an existing Thing, can thereby cause the Things service to issue arbitrary HTTP GET requests from inside the deployment's network — including to cloud instance-metadata endpoints and other internal services — and can use the differing error responses returned to the caller to enumerate internal services. Versions 2.4.0 to 2.5.x contain the same code, but are only affected where the operator explicitly enabled the WoT integration feature toggle, which is disabled by default in those versions.

EG Risk is EchelonGraph's 0–100 priority score: it fuses intrinsic severity with real-world exploitation and automatability so you can rank equal-severity CVEs and fix the most dangerous first. Higher = act sooner. Distinct from the 0–10 EG Score (severity).
