CVE-2026-79088

MEDIUMCVSS · not yet scored6.5
EchelonGraph scoreLOW confidence

Google's Chromium security team rated this Medium in the advisory text — the exact wording is "(Chromium security severity: Medium)". Chromium's CNA does not publish a CVSS vector, and NVD has not yet analysed this record, so there is no CVSS v3.1, v4.0 or v2.0 base score for it from any source. EchelonGraph publishes 6.5 (MEDIUM), derived from the VENDOR'S OWN SEVERITY BAND — not from a CVSS vector. That number is calibrated, not assumed: across 859 Chromium CVEs that NVD has since scored, a Chromium "Medium" carried a median CVSS v3 base of 6.5. This score is provisional and will be superseded the moment any source publishes a real CVSS base. EPSS predicts 0.4% exploitation probability in the next 30 days, which is reflected in EG Risk but does not lift a vendor-band score. Confidence: LOW.

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).
