CVE-2026-114451
Kadence Memberships < 4.0.6 - Unauthenticated Table Collation Downgrade via 'rcp-action' Parameter
- A public exploit reference is listed
Description
The Membership Plugin WordPress plugin before 4.0.6 does not perform any authorization or CSRF check before running a schema-altering database maintenance routine, allowing unauthenticated users to convert the Membership Plugin WordPress plugin before 4.0.6's own tables to a narrower character set, which irreversibly replaces every 4-byte character (such as emoji and some CJK characters) in the membership level, discount code and payment records with a question mark.
