Can the CISA KEV catalog work as a WordPress vulnerability feed?

Only as an urgent signal. The KEV catalog lists confirmed exploited flaws and holds few WordPress items, so pair it with a broader plugin advisory feed.

Partly. CISA's Known Exploited Vulnerabilities catalog is a good urgent signal because every entry is confirmed exploited, and it comes as a JSON file you can filter. But it holds few WordPress items, so it cannot replace a feed that covers the many plugins on a typical site.

What the catalog is

CISA describes the KEV catalog as its authoritative list of vulnerabilities exploited in the wild, and advises organisations to use it as an input to their vulnerability management prioritisation. It is available as CSV and as JSON.

That makes it a prioritisation tool. Inclusion means attackers have used the flaw, which is a stronger signal than a severity score alone. It does not mean the catalog lists every risky plugin.

How small the WordPress slice is

The JSON feed release dated 16 October 2026 held 1,748 entries. Filtering on the vendor project field set to WordPress returned six: three for WordPress core and three for plugins. One further entry named a hosting control panel product with WordPress in its product name. Counts change as CISA adds entries, so rerun the filter rather than quoting this number.

Each entry has fields including the CVE identifier, vendor and product, a short description, the date added, a required action and a due date. Those fields are enough to build a simple match.

How to use it for a WordPress estate

  1. Download the JSON on a schedule.
  2. Filter for WordPress in the vendor and product fields, and add the names of your key plugins.
  3. Match entries against your inventory of core version, plugins and themes.
  4. For any match, treat the due date as your own deadline and update or remove the component.
  5. Log what you did, with a date.

What it will miss

GapWhy
Vulnerable but not yet exploited pluginsNot in the catalog until exploitation is confirmed
Small pluginsFew get listed
Premium pluginsCoverage depends on public reporting
Your custom codeNever listed

So pair it with a feed that covers plugin vulnerabilities broadly, and with your own inventory. The catalog answers one question: which known issues must be fixed first. It does not answer which components you run.

A simple review habit

Put a recurring slot in the calendar, weekly for agencies and monthly for single sites, to refresh the file, rerun the filter and record the result even when nothing matches. A dated note that says no match this week is useful evidence that someone looked.

Make the inventory the foundation

Matching only works if you know your versions. Build the inventory first, then filter any feed against it. Safeguard can scan a repository for dependency manifests and produce an SBOM, and there is a free scan at gold.safeguard.sh/scan.

Quick check

Is every exploited WordPress plugin in the KEV catalog?

No. Entries depend on confirmed exploitation and CISA's criteria, so many exploited issues may be absent.

Is the KEV feed free?

CISA publishes it for public download as CSV and JSON.
