The Simple Yearly Archive plugin for WordPress is vulnerable to Stored Cross-Site Scripting via admin settings in versions up to, and including, 2.1.8 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with administrative-level permissions and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. This only affects multi-site installations and installations where unfiltered_html has been disabled.
|Software Slug||simple-yearly-archive (view on wordpress.org)|
|Remediation||Update to version 2.1.9, or a newer patched version|
