Name of the Vulnerable Software and Affected Versions IRM Newsroom plugin for WordPress versions up to, and including, 1.2.17

Description The issue is related to Stored Cross-Site Scripting via the plugin's 'irmcalendarview' shortcode due to insufficient input sanitization and output escaping on user-supplied attributes. This allows 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.

Recommendations For IRM Newsroom plugin for WordPress versions up to, and including, 1.2.17, update to a version that addresses the insufficient input sanitization and output escaping issue. As a temporary workaround, consider restricting access to the 'irmcalendarview' shortcode to prevent exploitation.
