Simple Yearly Archive <= 2.2.4 - Authenticated (Contributor+) Stored Cross-Site Scripting
No known patch is available for this vulnerability.
The affected plugin has not been updated on WordPress.org since before this CVE was disclosed; the latest installable version is still vulnerable. If you have the affected software installed, you should uninstall or replace it rather than wait for an update.
Description
The Simple Yearly Archive plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the posttype attribute of the SimpleYearlyArchive shortcode in all versions up to, and including, 2.2.4 due to insufficient input sanitization and output escaping on user supplied attributes. This makes it possible for authenticated attackers, with Contributor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.
