WordPress Security Advisory — REST API Batch Endpoint (CVE-2026-60137 / CVE-2026-63030) (Resolved) Critical

Affecting Other - Wordpress

Two critical WordPress core vulnerabilities have recently been disclosed. The first (CVE-2026-60137) is a SQL injection flaw in WordPress's query handling; the second (CVE-2026-63030) chains with it to allow unauthenticated remote code execution via the REST API. As an example of what this vulnerability allows, an attacker can create a new wordpress admin user into a website, thereby gaining full access at an administrative  level to the website.  Both are actively exploited in the wild and are listed on the CISA Known Exploited Vulnerabilities catalogue.  The combination of these CVEs and the resulting family of exploits are being referred to as 'wp2shell'.

We have deployed a network-level mitigation across shared hosting fleet on Thuirsday 23/07/2026 which blocks the affected REST API endpoint at the web server layer, protecting sites regardless of their WordPress version. The fix is available in WordPress 7.0.2 (and 6.8.6 / 6.9.5 for older branches - the vulnerability was introduced in 6.0). We recommend updating WordPress core at your earliest convenience.

In some cases the mitigation may affect certain WordPress admin features, most commonly the Appearance -> Widgets editor. If you experience issues with your WordPress dashboard, please open a support ticket and we can apply an exemption to updated Wordpress websites.

Our JetBackup backup service is currently undergoing maintenance while our engineers expand the capacity and improve performance of our backup systems.


This will mean that JetBackup backups will not be available for recovery during this maintenance period.  We expect JetBackup in Plesk and cPanel control panels to be available again on Monday.


Please note that backups are still being taken - should you need to restore files, databases or email, please raise a support ticket and our engineers will complete that process for you.

Dear 1st Domains customers,

Due to a significant hardware failure around 9am this morning, our hosted exchange service is currently unavailable. Work is underway to recover the service, which we expect to be restored later this afternoon.  There should be no significant loss of data, excepting the period where the server was unavailable.
