Description

Statamic is a Laravel and Git powered content management system (CMS). Prior to versions 5.73.16 and 6.7.2, the user:reset_password_form tag could render user-input directly into HTML without escaping, allowing an attacker to craft a URL that executes arbitrary JavaScript in the victim's browser. This has been fixed in 5.73.16 and 6.7.2.

Detection & mitigation playbook

Open-source dependency

  1. Detect

    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.

  2. Fix

    Update statamic/cms to 5.73.16 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2026-33883 is resolved across your whole dependency graph.

  3. 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.
