What is known
The Spiffy Calendar WordPress plugin before 4.9.9 doesn't check the event_author parameter, and allows any user to alter it when creating an event, leading to deceiving users/admins that a page was created by a Contributor+.
Business impact
Successful exploitation of CVE-2024-0855, a medium vulnerability (CVSS 5.3) affecting spiffy calendar, may affect the confidentiality, integrity or availability of the vulnerable environment. The exact impact depends on the installed version, exposed interfaces and deployment configuration.
