CVE-2026-30878 · baserCMS: Mail Form Acceptance Bypass via Public API
This page contains facts from public vulnerability sources. Check the original advisory before updating.
baserCMS is a website development framework. Prior to version 5.2.3, a public mail submission API allows unauthenticated users to submit mail form entries even when the corresponding form is not accepting submissions. This bypasses administrative controls intended to stop form intake and enables spam or abuse via the API. This issue has been patched in version 5.2.3.
