Summary On July 17, 2026, the WordPress security team disclosed two chained vulnerabilities in WordPress core, publicly referred to as "wp2shell": - CVE-2026-60137 — a SQL injection issue in WordPress core (WP_Query / author__not_in). - CVE-2026-63030 — a REST API batch-route confusion issue which, chained with the above, can lead to unauthenticated remote code execution. Who is affected This affects specific versions of WordPress core: - 6.9.x — affected by both issues (RCE-capable). Patched in 6.9.6. - 7.0.x — affected by both issues (RCE-capable). Patched in 7.0.2. - 6.8.x — affected by the SQL injection issue only (not the full RCE chain). Patched in 6.8.6. Sites already on 6.8.6 / 6.9.6 / 7.0.2 or later, or on versions prior to 6.8, are not affected by this chain. Why it matters Chained together, these vulnerabilities can allow an unauthenticated attacker to execute code against a vulnerable site. Pantheon’s immutable containers prevent the deployment of webshells, bitcoin miners, or other exploits that leverage a downloaded payload in production environments. However, SQL Injection can still be used to deface or hijack sites. Because working exploits are publicly available, we expect attack volume to rise. What you should do — action required Update WordPress core to a patched version as soon as possible — 7.0.2, 6.9.6, or 6.8.6 depending on your branch — from your Pantheon Dashboard or via Terminus. Updating core is the definitive fix. See the WordPress 7.0.2 Security Release note: https://docs.pantheon.io/release-notes/2026/07/wordpress-7-0-2 What Pantheon is doing - We are actively monitoring platform traffic for exploitation attempts targeting the affected REST API endpoint. - We have observed sites being probed for vulnerability and have actively mitigated against sources of scripted activity already. - We are deploying targeted mitigations at the network level to programmatically prevent exploit attacks across the platform and can confirm that released exploit code is being mitigated. - Will update this post with more information as those efforts progress.

We can observe our mitigations denying an increasing volume of requests and are continuing to gather data to enhance our response. We will provide an update Tuesday morning.

We are continuing to monitor traffic patterns and adapt network-level mitigations in response.

Network mitigations are now active and successfully blocking exploit attempts against vulnerable API endpoints without affecting normal site operations. Continuous monitoring is in place. This platform-level mitigation is a safeguard, not a permanent fix for your application. To fully secure your environment, update WordPress core immediately as detailed in the Pantheon Documentation: https://docs.pantheon.io/core-updates

This incident has been resolved.

We are investigating reports of slow load times and degraded performance within the Pantheon Dashboard. Traffic to live sites is routing normally and is not impacted by this event. Our Engineering team is actively working to identify the root cause and restore full Dashboard functionality.

Investigation into the Pantheon Dashboard performance degradation is ongoing. For critical support outside the dashboard interface, email [email protected] immediately. Next update: Between 30 minutes and 3 hours.

A fix has been implemented and we are monitoring the results.

This incident has been resolved. The Pantheon Dashboard is performing normally, and loading times remain completely stable.

Sites are unable to complete builds via Integrated Composer. Builds complete successfully but fail at the final step when the platform attempts to push build artifacts back to the site's Git repository. Customers will see their deploy workflow fail with a pre-receive hook declined error. No data loss is occurring. Live sites are not affected; only new code deployments are blocked. We have identified the root cause. A dependency version mismatch on a subset of our Git servers is causing a server-side pre-receive hook to crash when build artifacts are pushed. This is a Pantheon infrastructure issue and is not caused by any customer code or configuration. No action is required on your end. Do not make changes to your repository or Composer configuration. We will update this page as remediation progresses. We will update within 2 hours, or sooner if the status changes.

We have identified that this may partially affect spinning up of Multidev environments. We are continuing to work on a fix for this issue. The next update will be in 2 hours or as soon as we have more details.

A fix has been deployed, and the Dashboard is now displaying successful Git operations. We are monitoring the affected sites closely to ensure related features are functioning within expectation to confirm issues are completely resolved. We will provide a final update once the resolution is verified. If you continue to experience the same issue, please contact us directly at [email protected].

A fix has been deployed, and the Pantheon Dashboard is now performing normally with stable loading times. A runtime upgrade in our API layer recently reduced the size of an internal connection pool used for resolving service addresses. Under normal traffic, this caused requests to queue up waiting for available connections instead of being processed immediately, adding several seconds of delay to page loads and API responses across the dashboard. Our Engineering team is monitoring the environment closely to ensure performance remains stable and to confirm the issue is completely resolved. We will provide a final update once the resolution is verified. If you continue to experience any performance degradation, please contact us directly at [email protected].
