THIS IS A SCHEDULED EVENT Oct <var data-var='date'>13</var>, <var data-var='time'>18:00</var> - <var data-var='time'>19:00</var> PDT Oct <var data-var='date'>13</var>, <var data-var='time'>18:00</var> PDT Scheduled - As part of the upcoming 10/13 routine maintenance window, updates to two systems will result in limited service interruptions: 1. Site management workflow systems: We will update the systems that process deployments, database operations, and other site management workflows. These workflows will be temporarily interrupted, and jobs queued before the maintenance window may fail. 2. Next.js request-routing service: We will update the security settings for the service that routes requests to Next.js sites. Next.js sites may experience a brief interruption while this work is completed. We recommend avoiding deployments and other site management workflows during the maintenance window. While we do not anticipate any impact to uptime for WordPress or Drupal sites during this maintenance window, Next.js sites may experience a brief interruption.

Routine Maintenance Impacting Site Management Operations

Oct <var data-var='date'> 6</var>, <var data-var='time'>15:21</var> PDT Resolved - This incident has been resolved. Oct <var data-var='date'> 5</var>, <var data-var='time'>11:08</var> PDT Update - Remediation and platform hardening remain ongoing. We are continuing to monitor systems closely while working directly with affected customers. Oct <var data-var='date'> 3</var>, <var data-var='time'>09:29</var> PDT Update - We are continuing to monitor and work through the remaining remediation and hardening. Our initial response is complete, and we are now working directly with the affected customers on site cleanup and credential rotation. We have added further protections and monitoring to help prevent and detect this type of activity. Based on the information available to us, we have found no evidence that any other customer's site or data was accessed. We will share another update as the remaining work progresses. As a reminder, the most effective protection is keeping your site current: please keep your CMS, plugins, themes, and modules up to date, remove anything you no longer use, review your user and credential access, and contact Pantheon Support if you notice unexpected code, deployments, or other changes on your site. Oct <var data-var='date'> 2</var>, <var data-var='time'>08:05</var> PDT Update - As our investigation has continued, we have determined that a small number of customer sites — not one — were affected. In each case, the site was first compromised through a weakness in its own application, then used to interact with platform services. We are working directly with the affected customers on cleanup and credential rotation, and we have added platform controls to restrict this activity and detection to identify it going forward. The activity remains limited to the individual affected sites and their own data. We have found no evidence that any other customer's site or data was accessed. What you can do: Keeping your site current is the most effective protection. Please update your CMS core, plugins, themes, and modules to the latest versions; remove plugins, themes, and modules you don't use; and delete sites you no longer need. If you notice unexpected code, deployments, or changes on your site, contact Pantheon Support. We will continue to post updates here. Oct <var data-var='date'> 1</var>, <var data-var='time'>12:38</var> PDT Monitoring - Beginning September 29, Pantheon identified malicious activity in which an attacker gained control of a customer website and used it to target platform resources. Activity from the compromised site attempted to exploit a Linux kernel vulnerability (CVE-2026-53362) on platform application hosts, and some sites may have briefly experienced interruptions as a result. We have taken the following actions: - Disabled and deleted the affected site. - Accelerated the operating-system and kernel updates already in progress, bringing application hosts to a version that addresses this vulnerability. - Deployed additional platform protections and monitoring. We have notified the affected customer directly. The compromise was limited to that single site; based on the information available to us, we have found no evidence of platform-wide data exfiltration or that this activity exposed data belonging to other customers. We are continuing to review platform activity and will update this advisory if that changes. How to protect your site: Attackers most often gain control of a site through outdated or unmaintained code. Keeping your site current is the most effective protection. We strongly encourage all customers to keep CMS core, plugins, and themes fully updated, remove and delete sites and code you no longer use, and review user and credential access. If you notice unexpected code, deployments, or changes on your site, contact Pantheon Support. We will post updates here as more information becomes available. If you have questions, please contact Pantheon Support.

Appserver availability interruptions

Sep <var data-var='date'>15</var>, <var data-var='time'>12:51</var> PDT Resolved - This incident has been resolved. Sep <var data-var='date'>14</var>, <var data-var='time'>18:01</var> PDT Update - We have completed mitigation for this incident. All confirmed affected accounts have had passwords reset and unauthorized access, machine tokens, and SSH keys revoked. All confirmed affected account holders and site owners have been contacted directly. We will continue monitoring the situation and share an update if anything changes. Sep <var data-var='date'>14</var>, <var data-var='time'>00:02</var> PDT Update - We have no new developments to share. We're continuing to keep the affected accounts secure, including resetting passwords and revoking any unauthorized access, machine tokens, and SSH keys. Pantheon's systems were not compromised. We're continuing to reach out to affected account holders and site owners directly with guidance on next steps. Sep <var data-var='date'>13</var>, <var data-var='time'>09:26</var> PDT Monitoring - We have completed mitigation steps for the compromised accounts, including resetting passwords and revoking unauthorized access, machine tokens, and SSH keys. We are continuing to notify affected account holders and site owners directly. Customers who are affected will receive specific guidance from Pantheon through our support channels. Pantheon’s systems were not compromised. We will continue monitoring the situation and provide further updates as our review progresses. Sep <var data-var='date'>12</var>, <var data-var='time'>15:51</var> PDT Identified - We have identified the cause of this incident and are actively responding. Our evidence indicates the affected accounts were accessed using passwords captured on a fraudulent copy of the Pantheon login page, reached through sponsored search results and not through any compromise of Pantheon's own systems We are securing the affected accounts, resetting credentials, and revoking access created by the unauthorized party. As part of this, you will receive a routine password-reset email. We are also contacting affected account holders and site owners directly; those security notifications will come from helpdesk@pantheon.io and are genuine. Sep <var data-var='date'>12</var>, <var data-var='time'>09:58</var> PDT Update - We are correcting our initial assessment. Our earlier update said the affected accounts were accessed with passwords stolen in third-party data breaches. Our evidence indicates that credentials were captured on a fraudulent copy of the Pantheon sign-in page. The look-alike page was promoted through paid search results and links, and it forwarded users to the real Pantheon Dashboard after capturing what they typed, so many affected users saw nothing unusual. We have identified and reported one such site. Sites of this kind are usually replaced quickly. We are continuing to search for others and to work with the providers involved. Pantheon's systems were not breached. Once inside an account, the unauthorized party used normal account functions: creating machine tokens, adding SSH keys, and on some affected sites, deploying code to production. We will be contacting affected account holders and site owners directly once we confirm the list of affected accounts, resetting credentials, and revoking tokens and keys on those accounts. If you are not contacted, we have no indication your account was accessed. How to protect your account Sign in only by typing https://dashboard.pantheon.io into your browser or using a bookmark you created. Do not sign in from a search result, a sponsored ad, or a link in an email or chat message, even one that appears to come from Pantheon. Before you type a password, check that the address bar shows dashboard.pantheon.io spelled exactly; look-alike pages differ by a letter or two. Turn on multi-factor authentication for your Pantheon account (Personal Settings, then Security). Instructions: https://docs.pantheon.io/release-notes/2026/04/mfa If you have signed in from a search result or emailed link recently, change your password now, then review your account: remove SSH keys you do not recognize (https://docs.pantheon.io/ssh-keys), revoke machine tokens you did not create (https://docs.pantheon.io/machine-tokens), and check your site and workspace team lists for members you did not add. Pantheon will never ask for your password by email, chat, or phone. Report suspicious sign-in pages or messages to abuse@pantheon.io. Our security practices and contacts are published at https://pantheon.io/security and https://trust.pantheon.io. Sep <var data-var='date'>12</var>, <var data-var='time'>03:18</var> PDT Update - Our team is still investigating the issue. The next update will be in 6 hours or when a new major update comes. Sep <var data-var='date'>11</var>, <var data-var='time'>21:16</var> PDT Update - We are continuing to investigate this issue. Sep <var data-var='date'>11</var>, <var data-var='time'>21:13</var> PDT Investigating - We are currently investigating reports of unauthorized access to a small number of Pantheon customer accounts. Our evidence suggests these accounts were accessed using credentials stolen from external third-party data breaches (unrelated to Pantheon). This technique, known as "credential stuffing," relies on reused passwords.

Site availability issues

Jul <var data-var='date'>21</var>, <var data-var='time'>14:33</var> PDT Resolved - This incident has been resolved. Jul <var data-var='date'>21</var>, <var data-var='time'>14:33</var> PDT Update - 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 Jul <var data-var='date'>21</var>, <var data-var='time'>06:43</var> PDT Update - We are continuing to monitor traffic patterns and adapt network-level mitigations in response. Jul <var data-var='date'>20</var>, <var data-var='time'>15:20</var> PDT Update - 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. Jul <var data-var='date'>20</var>, <var data-var='time'>12:26</var> PDT Monitoring - 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.

Jul <var data-var='date'> 3</var>, <var data-var='time'>02:20</var> PDT Update - 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. Jul <var data-var='date'> 2</var>, <var data-var='time'>23:50</var> PDT Identified - 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.
