These vulnerabilities could potentially allow unauthorized individuals to execute malicious code on affected servers, creating security risks for websites and the information they manage. At CatapultCMS, we take these security concerns seriously and have taken action to address the vulnerabilities within our hosting environment. --- ### **What has CatapultCMS Done?** Our Development team has reviewed the reported PHP vulnerabilities and **deployed a security patch to address the identified risks** across our affected hosting infrastructure. This update was prioritized to help protect our clients' websites and maintain the security of our platform. We will continue to monitor developments related to these vulnerabilities and take additional action if necessary. --- ### **Will This Affect My Website?** While the security update has been deployed, we have identified a temporary issue affecting the A-Z sitemap functionality on some websites. **What you may experience:** - The A-Z sitemap page may load without displaying its usual list of links. - Other website pages and navigation are not currently known to be affected by this particular issue. Our Development team has identified a resolution and is actively working to restore this functionality across affected websites. Some websites will receive the correction automatically through our scheduled update process, while others may require additional updates from our team. --- ### **Do I Need to Take Any Action?** **No action is required from clients to apply the PHP security patch.** CatapultCMS has already deployed the necessary security update. If you notice that your A-Z sitemap is not displaying links correctly, please contact our Support team so we can review your website and assist with restoring the functionality. --- ### **Question or Concerns?** We understand that reports of security vulnerabilities can raise concerns, especially for organizations that rely on their websites to communicate important information. Our team remains committed to maintaining a secure and reliable platform, and we appreciate your patience as we complete the remaining functionality updates. If you have questions regarding this security update or notice any unexpected website behavior, please contact [**CatapultCMS Support**](https://support.catapultcms.com/kb-tickets/new?hsLang=en) for assistance. - [CMS](https://support.catapultcms.com/cms?hsLang=en#main-content) - [Getting Started with Catapult CMS](https://support.catapultcms.com/cms?hsLang=en#getting-started-with-catapult-cms) - [The Dashboard](https://support.catapultcms.com/cms?hsLang=en#the-dashboard) - [General Editing Information](https://support.catapultcms.com/cms?hsLang=en#general-editing-information) - [Basic Elements](https://support.catapultcms.com/cms?hsLang=en#basic-elements) - [Visual Elements](https://support.catapultcms.com/cms?hsLang=en#visual-elements) - [File Management](https://support.catapultcms.com/cms?hsLang=en#file-management) - [Integrations](https://support.catapultcms.com/cms?hsLang=en#integrations) - [Compliance](https://support.catapultcms.com/cms?hsLang=en#compliance) - [Configuration](https://support.catapultcms.com/cms?hsLang=en#configuration) - [Implementation](https://support.catapultcms.com/cms?hsLang=en#implementation) - [Connect](https://support.catapultcms.com/connect?hsLang=en#main-content) - [Manage Users](https://support.catapultcms.com/connect?hsLang=en#manage-users) - [SIS Configuration](https://support.catapultcms.com/connect?hsLang=en#sis-configuration) - [Dashboard](https://support.catapultcms.com/connect?hsLang=en#dashboard) - [Other](https://support.catapultcms.com/connect?hsLang=en#other) - [Organization & Site Resources](https://support.catapultcms.com/connect?hsLang=en#organization-site-resources) - [Messages](https://support.catapultcms.com/connect?hsLang=en#messages) - [Emergency Resources](https://support.catapultcms.com/connect?hsLang=en#emergency-resources) - [Implementation](https://support.catapultcms.com/connect?hsLang=en#implementation) - [APP](https://support.catapultcms.com/app?hsLang=en#main-content) - [App Management](https://support.catapultcms.com/app?hsLang=en#app-management) - [What's New](https://support.catapultcms.com/whats-new?hsLang=en#main-content) - [What's new at CatapultCMS](https://support.catapultcms.com/whats-new?hsLang=en#whats-new-at-catapultcms) - [Contact Us](https://support.catapultcms.com/contact-us?hsLang=en) - [Incident Report](https://support.catapultcms.com/incident-report?hsLang=en) - [Implementation](https://support.catapultcms.com/implementation?hsLang=en#main-content) - [Professional Add-On Services](https://support.catapultcms.com/implementation?hsLang=en#professional-add-on-services) [![catapult-cms-logotype](https://support.catapultcms.com/hs-fs/hubfs/catapult-cms-logotype.png?width=250&height=49&name=catapult-cms-logotype.png "catapult-cms-logotype")](https://catapultcms.com/) [CatapultCMS.com](https://catapultcms.com/) [CMS Login](https://www.catapultcms.com/Login.aspx) [CONNECT Login](https://www.catapult-connect.com/Account/Login?ReturnUrl=%2F) Copyright © 2026, CatapultCMS
