A critical pre-authentication RCE vulnerability (CVE-2026-63030, CVSS 9.8) and a medium-severity SQL injection (CVE-2026-60137, CVSS 5.9) in WordPress Core allow remote code execution via malicious HTTP requests to the batch API. The NCSC expects imminent exploitation and strongly advises applying the available security updates immediately. If patching is not possible, apply the mitigating measures detailed by Searchlight Cyber.
Security Advisories Download Security Advisory; NCSC-2026-0250 [1.0.0] Security Advisory NCSC-2026-0250 [1.0.0] Publicatie 18-07-2026 13:01 (Europe/Amsterdam) Prioriteit Normaal Betreft Kwetsbaarheden verholpen in WordPress door Automattic Kenmerken Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection') Interpretation Conflict Omschrijving Er zijn twee kwetsbaarheden verholpen in WordPress Core 6.8.6, 6.9.5 en 7.0.2 Een ongeauthenticeerde kwaadwillende kan de kwetsbaarheden op afstand misbruiken voor het uitvoeren van willekeurige code. Hiertoe dient een malafide HTTP-request naar de batch-API van een WordPress-site te worden verstuurd. Aangezien kwetsbaarheden in contentmanagementsystemen structureel de interesse van kwaadwillenden hebben, verwacht het NCSC dat de kwetsbaarheden op korte termijn zullen gaan worden misbruikt. Oplossingen WordPress heeft beveiligingsupdates beschikbaar gesteld om de kwetsbaarheden te verhelpen. Het NCSC adviseert om deze updates op korte termijn te installeren. Indien het installeren van de beveiligingsupdates niet mogelijk is, kan misbruik worden voorkomen door de mitigerende maatregelen toe te passen die door beveiligingsbedrijf Searchlight Cyber zijn gedeeld.
