CVE-2026-110010— MB Custom Post Types & Custom Taxonomies 2.0.2 - 2.12.2 - Unauthenticated Settings Reset via 'mbcpt-force' Parameter

Quick assessment

Affected
Unknown MB Custom Post Types & Custom Taxonomies
Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

在版本 2.12.3 之前，WordPress 插件"MB Custom Post Types & Custom Taxonomies"未在执行任何权限或身份验证检查的情况下，允许未认证用户重新运行遗留数据迁移功能。这使得任何人均可将自 2.0 版本之前升级而来的站点中的自定义文章类型或分类法定义，回退至升级前的状态。该行为会丢弃管理员在升级后所做的配置更改；若这些更改曾限制了某定义的可见性，则会静默地重新向匿名访客暴露该定义及其内容。

Vulnerability Title
MB Custom Post Types & Custom Taxonomies 2.0.2 - 2.12.2 - Unauthenticated Settings Reset via 'mbcpt-force' Parameter
Source: CVE Program / CVE List V5
Vulnerability Description
The MB Custom Post Types & Custom Taxonomies WordPress plugin before 2.12.3 does not perform any capability or authentication check before allowing an unauthenticated request to re-run a legacy data migration, letting anyone revert a custom post type or taxonomy definition on sites upgraded from a pre-2.0 release back to its pre-upgrade state. This discards configuration changes an administrator made after upgrading and, where those changes had restricted a definition's visibility, silently re-exposes the definition and its content to anonymous visitors.
