CVE-2026-27196Network attack vector

Privilege escalation via unsanitized HTML field rendering

Published Feb 21, 2026 · Updated Feb 21, 2026

Stored XSS in Statamic CMS before 5.73.9 and 6.0.0-alpha.1 through 6.3.1 allows remote authenticated users to run JavaScript. HtmlFieldtype.vue passed the configured html value directly to Vue's v-html directive without sanitization, causing a viewer's browser to interpret injected markup and scripts. Field-management permission is required to store the payload, and execution requires a higher-privileged user to view the affected HTML field in the control panel, allowing privilege escalation through that user's session.
