Description
Statamic is a Laravel and Git powered content management system (CMS). Prior to 5.74.3 and 6.24.2, the default ("automagic") form notification email rendered user-submitted values without escaping, allowing an unauthenticated form submitter to inject HTML into the notification emails sent to the configured recipients. This issue is fixed in versions 5.74.3 and 6.24.2.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for statamic/cms, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.
Fix
Update statamic/cms to 5.74.3 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2026-71435 is resolved across your whole dependency graph.
Workarounds
Escape or sanitise the affected output on the server side rather than relying on client-side filtering, and add a Content-Security-Policy that blocks inline script execution so injected markup cannot run even if it reaches the page.
