DescriptionCVE.org

The IRM Newsroom plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the plugin's 'irmcalendarview' shortcode in all versions up to, and including, 1.2.17 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.

AnalysisAI

Stored cross-site scripting in IRM Newsroom plugin for WordPress allows authenticated attackers with contributor-level access or higher to inject arbitrary web scripts via the 'irmcalendarview' shortcode. The vulnerability affects all versions up to and including 1.2.17, and no public exploit or active exploitation has been identified at this time.

Technical ContextAI

The vulnerability is a stored cross-site scripting (XSS) issue, classified under CWE-79, which occurs due to insufficient input sanitization and output escaping on user-supplied attributes in the 'irmcalendarview' shortcode. The affected product is the IRM Newsroom plugin for WordPress, identified by CPE cpe:2.3:a:irmau:irm_newsroom:*:*:*:*:*:wordpress:*:*. The plugin is installed on WordPress sites and allows users to display newsroom calendars. The shortcode attribute handling lacks proper escaping, enabling attackers to inject malicious scripts that are stored and executed when other users view the page.

The patch is available via the WordPress plugin repository; the changeset can be viewed at https://plugins.trac.wordpress.org/changeset/3312832.
