CVE-2026-27126
Craft is a content management system (CMS).
Published Feb 24, 2026 · corrected/updated Jun 17, 2026 · craftcms craft cms · evidence confidence medium
Craft is a content management system (CMS). In versions 4.5.0-RC1 through 4.16.18 and 5.0.0-RC1 through 5.8.22, a stored Cross-site Scripting (XSS) vulnerability exists in the component when using the column type. The application fails to sanitize the input, allowing an attacker to execute arbitrary JavaScript when another user views a page with the malicious table field. In order to exploit the vulnerability, an attacker must have an administrator account, and must be enabled in production, which is against Craft's security recommendations. Versions 4.16.19 and 5.8.23 patch the issue.
