The CP Multi View Event Calendar plugin by codepeople suffers from a stored cross-site scripting vulnerability due to improper input neutralization during web page generation. This allows an attacker with low privileges and requiring user interaction to inject malicious scripts that can compromise confidentiality, integrity, and availability to a limited extent. The vulnerability affects versions up to 1.4.36. No patch or official fix information is currently available.

Successful exploitation could allow an attacker to execute arbitrary scripts in the context of other users, potentially leading to information disclosure, modification of data, or disruption of service. The impact is rated medium with partial confidentiality, integrity, and availability loss. No known exploits have been reported in the wild.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, users should exercise caution with user-supplied input and consider applying temporary mitigations such as input validation or disabling the plugin if feasible.
