DescriptionCVE.org

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 author__not_in WP_Query SQL Injection (CVE-2026-60137), could allow an attacker to perform SQL Injection and achieve Remote Code Execution.

AnalysisAI

Remote code execution in WordPress 6.9.x (before 6.9.5) and 7.0.x (before 7.0.2) arises from a REST API batch endpoint route confusion flaw that, when chained with the author__not_in WP_Query SQL injection (CVE-2026-60137), lets attackers inject SQL and ultimately execute arbitrary code on the underlying host. Publicly available exploit code exists (a ProjectDiscovery Nuclei template and WPScan advisory), and the CISA SSVC framework rates the flaw as automatable with total technical impact, though it is not currently listed in CISA KEV. …

Vulnerability AssessmentAI

Exploitation Exploitation requires the target to be running an affected WordPress core version (6.9.0-6.9.4 or 7.0.0-7.0.1) with the REST API enabled and the /batch/v1 batch endpoint reachable - both are on by default in a stock WordPress installation. … Additional conditions and limiting factors are described in the full assessment.
Risk Assessment This is a genuine high-priority issue rather than an inflated CVSS score. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in.
Exploit Scenario An unauthenticated attacker sends a crafted request to the WordPress REST API batch endpoint that exploits the route confusion to smuggle a malicious author__not_in parameter into a WP_Query-backed sub-request, triggering the CVE-2026-60137 SQL injection. The injected query is leveraged to read or modify database contents and pivot to remote code execution on the server. …
Remediation Vendor-released patch: upgrade WordPress to 7.0.2 (for the 7.0.x branch) or 6.9.5 (for the 6.9.x branch); sites with automatic background minor updates enabled will typically receive the release automatically, but this should be verified. … Detailed patch versions, workarounds, and compensating controls in full report.

Recommended ActionAI

Within 24 hours, audit all WordPress installations to identify instances running versions 6.9.0-6.9.4 or 7.0.0-7.0.1, prioritizing internet-facing systems. …
