CVE-2026-110010
Last modified
CVE-2026-110010 is a medium-severity vulnerability rated 4.8/10 on the CVSS scale. 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.. EPSS estimates a 0.17% chance of exploitation in the next 30 days.
