CVE-2020-9054

CVSS 9.8 In CISA KEV Zyxel

Every applicability statement published about this vulnerability, kept as each source wrote it rather than merged into one verdict. Where sources disagree, both positions are shown.

Does it affect your version?

A statement that names no version covers the whole product, which is not the same as your version falling inside a range. Orderings marked best effort come from schemes with no published comparison algorithm; exact ones follow a published specification.

What each source says

CVE List v5 (CNA container)
precedence 60 · revised 2025-10-21
13 affected

Precedence decides which claim wins when two sources describe the same product over the same version range. It is a property of the source, not of the claim, and changing it re-ranks the data without re-reading a single document.

A claim with no version range is shown as written rather than expanded: a government catalog naming only a vendor and product is a real statement at zero granularity, and inventing bounds for it would put precision in the record that the source never offered.
