# CVE-2026-63030: WordPress Core Interpretation Conflict Vulnerability

**Signal:** Exploited: patch now if you run it. CISA has confirmed exploitation in the wild. (Computed from CISA KEV, EPSS and CVSS; not an editorial verdict.)

## Should you act?

- Yes, if you run WordPress Core. CISA added this CVE to its Known Exploited Vulnerabilities catalog on 2026-07-21, which means there is reliable evidence of exploitation in the wild. US federal agencies must remediate by 2026-07-24 ; treat that as the outer limit, not the target.
- EPSS 10.6% , percentile 96: FIRST’s model estimates a 10.6% chance of exploitation activity in the next 30 days, higher than 96% of all scored CVEs (very high). EPSS is a probability, not a verdict.
- Remotely reachable with no login and no user interaction. If the vulnerable service is exposed to the internet, prioritize it.
- Editorial verdict: Act now. WordPress 7.0.2: REST Batch + SQL Injection Chain to RCE — Core WordPress 6.9 and 7.0 sites were exposed to unauthenticated remote code execution that is now exploited; most sites got a forced update, so your job is to confirm every one actually did.

## What it is

WordPress 6.9.x before 6.9.5 and 7.0.x before 7.0.2 is affected by a REST API batch endpoint route confusion issue which, combined with the authornotin WPQuery SQL Injection (CVE-2026-60137), could allow an attacker to perform SQL Injection and achieve Remote Code Execution.

## Affected products (CVE record)

- WordPress WordPress: 6.9.0 < 6.9.5, 7.0.0 < 7.0.2

## Severity

- WPScan CVSS 3.1: 9.8 `CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H`

## Exploitation

- CISA KEV: added 2026-07-21; federal due date 2026-07-24. Known ransomware use: Unknown.
- CISA required action: 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.
- CISA SSVC assessment: exploitation active , automatable yes , technical impact total .
- FIRST EPSS (model of 2026-10-21): 10.65% probability of exploitation activity in the next 30 days; percentile 96.
