Summary
by MITRE • 02/21/2026
Statmatic is a Laravel and Git powered content management system (CMS). Versions 5.73.8 and below in addition to 6.0.0-alpha.1 through 6.3.1 have a Stored XSS vulnerability in html fieldtypes which allows authenticated users with field management permissions to inject malicious JavaScript that executes when viewed by higher-privileged users. This issue has been fixed in 6.3.2 and 5.73.9.

The vulnerability identified as CVE-2026-27196 affects Statmatic, a content management system built on Laravel and Git technologies. This system serves as a platform for managing digital content through various field types including HTML fields. The security flaw manifests as a stored cross-site scripting vulnerability that specifically targets HTML fieldtypes within the CMS interface. The vulnerability exists in multiple versions including all releases up to and including 5.73.8, as well as the alpha and beta releases from 6.0.0-alpha.1 through 6.3.1, making it a widespread issue affecting both stable and development versions of the software.
The technical nature of this vulnerability stems from insufficient input validation and output sanitization within the HTML fieldtype processing mechanisms. When authenticated users with field management permissions create or modify content using HTML fields, the system fails to properly sanitize or escape the input before storing it in the database. This allows malicious JavaScript code to be persistently stored within the CMS and subsequently executed whenever the content is rendered or viewed by other users. The vulnerability is particularly dangerous because it requires only field management permissions rather than administrative privileges, making it accessible to users who should have limited access to system functionality.
The operational impact of this stored XSS vulnerability is significant as it creates a persistent attack vector that can be exploited by users with relatively low privileges within the system. When higher-privileged users view content containing the malicious JavaScript, the code executes in their browser context, potentially leading to session hijacking, credential theft, or unauthorized actions within the CMS. The vulnerability affects the integrity and confidentiality of the system by allowing attackers to execute arbitrary code in the browsers of legitimate users. Given that the CMS handles content management for various users and potentially sensitive data, this vulnerability could enable attackers to escalate their privileges or access restricted areas of the system.
The fix implemented in versions 6.3.2 and 5.73.9 addresses this vulnerability through proper input sanitization and output encoding mechanisms. These updates ensure that HTML field content is properly escaped and validated before being stored and rendered, preventing malicious JavaScript from being executed. Organizations using affected versions should immediately upgrade to the patched releases to mitigate the risk. Security measures should also include implementing proper access controls, monitoring user activities related to field management, and conducting regular security assessments of CMS components. The vulnerability aligns with CWE-79 which categorizes cross-site scripting flaws, and could be exploited through ATT&CK techniques related to privilege escalation and credential access through web application vulnerabilities.
