7.2High

Attack vector: Network
Complexity: Low
Privileges needed: None
User interaction: None
Impact: Limited impact
Weakness: CWE-79

Impact

Unauthenticated attackers can inject persistent malicious scripts to hijack user sessions or deface pages. This requires network access and an admin having enabled the 'Allow edition in frontend?' setting on at least one calendar view.

Root cause

The CalendarTitle parameter in the plugin's frontend editor lacks proper input sanitization and output escaping.

Affected systems

CP Multi View Events Calendar plugin for WordPress versions up to and including 1.4.42.

CVSS v3.1 · CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:L/I:L/A:N

Fix & remediation

Upgrade to a version newer than 1.4.42 once available. As an immediate mitigation, disable the 'Allow edition in frontend?' option across all calendar configurations to shut down the public endpoint.

shell

$ wp plugin update cp-multi-view-calendar

NVD description

The CP Multi View Events Calendar plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'CalendarTitle' parameter in all versions up to, and including, 1.4.42 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. This requires that an administrator has enabled the "Allow edition in frontend?" option on at least one calendar view, which exposes the unauthenticated add endpoint and a publicly accessible nonce.
