WordPress Core Rating: A Simple Score for Your Site’s Core Health
Your WordPress core is the backbone of your site’s security and stability. The WordPress Core Rating simplifies complex vulnerability data into a single, actionable score that you can track and improve over time.
What the WordPress Rating Measures
The WordPress Core Rating provides a 1–6 score that reflects:
- Whether your current WordPress version has known vulnerabilities
- Whether your core is flagged as outdated (if applicable)
How We Calculate the Score
We analyze your installed WordPress version and count vulnerabilities based on severity, including:
- Critical
- High
- Medium
- Low
- Outdated
If vulnerabilities are found, the score is determined by the worst severity level:
- Critical → 1
- High → 2
- Medium → 3
- Low/None but risk flags present → 4
- Outdated (no CVEs, but behind the latest version) → 5
If no vulnerabilities are detected, your WordPress core is scored:
- 6 (Secure)
In short: known CVEs (Common Vulnerability Exposures) will lower your score, while a clean, up-to-date core will give you the best rating.
Score Meanings at a Glance
Here’s a breakdown of what each WordPress Core Rating score means:
- 6 — Secure: No known vulnerabilities detected in your core.
- 5 — Outdated: No CVEs detected, but your core version is behind the latest stable release.
- 4 — At Risk: Low-level concerns present.
- 3 — At Risk: Medium severity vulnerabilities detected.
- 2 — Vulnerable: High severity vulnerabilities present.
- 1 — Critical: Critical vulnerabilities present; immediate action required.
Why WordPress Core Rating Matters
The WordPress Core Rating is crucial for several reasons:
- Security Hardening: Core CVEs are commonly scanned for and exploited, so patching them quickly is vital.
- Stability: Core fixes often resolve bugs that may affect themes and plugins, ensuring smooth operation.
- Compatibility: The WordPress ecosystem, including plugins and themes, is built around supported WordPress versions, ensuring better results with current releases.
How to Improve Your WordPress Rating
To improve your WordPress Core Rating:
- Patch Fast: Update to the latest stable WordPress release immediately.
- Validate Compatibility: Test the update in a staging environment to ensure compatibility with your theme and key plugins.
- Lock a Cadence: Apply minor updates automatically and review major updates as soon as they are available.
- Reduce Risk Exposure: Remove abandoned or unmaintained components that could block safe updates.
Example Scenarios
Here are some examples of how the WordPress Core Rating score is calculated:
- 1 High vulnerability in core → Score 2 (Vulnerable)
- No vulnerabilities, but version is behind → Score 5 (Outdated)
- No vulnerabilities detected → Score 6 (Secure)
