CVE-2026-63030: WordPress Core

According to CISA this vulnerability is already used in attacks (added on 21 July 2026).

Key facts

Description (CISA)

WordPress Core contains an interpretation conflict vulnerability that could allow an attacker to perform SQL Injection and achieve Remote Code Execution. This vulnerability can be chained with CVE-2026-60137.

Required action (CISA)

Apply mitigations in accordance with vendor instructions, ensuring compliance with CISA’s BOD 26-04 Prioritizing Security Updates Based on Risk (see URL in Notes) guidance and CISA’s “Forensics Triage Requirements” (see URL in Notes). Follow applicable BOD 26-04 guidance for cloud services or discontinue use of the product if mitigations are unavailable. Stakeholders are responsible for evaluating each asset's internet exposure and ensuring adherence to BOD 26-04 patching guidelines.

What admins should do now

1. Affected? Check whether WordPress Core is in use and which version runs (package manager, admin UI, --version).
2. Apply the vendor patch or workaround as soon as it exists. If that is not possible right away: restrict outside access (firewall, VPN, reverse proxy).
3. Review logs back to 21 July 2026: unusual logins, new files, unexpected processes, outbound connections.
4. If you suspect a compromise: isolate the system, rotate credentials, check the last backup from before the incident.

The deadline applies to US federal agencies. It is still a useful yardstick for everyone: when a flaw is attacked in the wild, waiting is not an option.
