3Zero Interpretation

The WordPress Core vulnerability history is long-running and varied rather than concentrated in a single release or weakness. The synchronized dataset contains 369 records published from June 2003 through July 2026. Cross-site scripting is the largest normalized category with 137 records (37.1%), followed by 40 missing-authorization and 36 information-disclosure records. The history also includes 16 critical and 92 high-severity records.

The latest records materially affect how this history should be read. The dataset identifies a critical remote-code-execution record affecting the 6.9 and 7.0 branches before 6.9.5 and 7.0.2, together with a high-severity SQL-injection record affecting several maintained branches. This demonstrates why WordPress Core maintenance should follow the supported release branch and security releases, not simply a fixed calendar schedule.

Of the 369 associated records, 367 are marked patched and two are currently marked unpatched in the synchronized source. Those counts describe source records; they do not establish that a particular website is exposed or compromised.

Practical Next Steps

Identify the exact Core release. Record the installed WordPress version and whether the site is following the current major branch or an older supported branch.
Compare it with the affected ranges. Recent source records list patched values including 7.0.2, 6.9.5 and 6.8.6. Use the branch-specific value shown for each record rather than treating one version number as universal.
Apply security releases with a tested recovery path. Take a verified backup, update Core, clear application and edge caches, then test login, publishing, REST API and scheduled tasks.
Review exposure separately from patching. If the site ran an affected release while a high-impact issue was public, review administrator accounts, file changes, request logs and unexpected scheduled activity. An affected version alone does not prove exploitation.
Keep automatic minor security updates observable. Confirm that update notifications, failure reporting and backups are functioning so a failed automatic update does not remain unnoticed.

Need help reviewing an exposed WordPress website?

Running an affected version does not prove that a website was compromised. Suspicious redirects, unknown administrators, injected content, unexpected files or recurring malware may require a manual investigation.
