The Ragic Shortcode plugin for WordPress suffers from a stored cross-site scripting vulnerability (CWE-79) due to improper neutralization of input during web page generation. Specifically, the plugin fails to properly sanitize and escape user-supplied attributes in its 'ragic' shortcode, allowing authenticated users with contributor-level permissions or higher to inject malicious JavaScript code. This code executes in the context of any user who views the injected page, potentially leading to session hijacking or other script-based attacks. The vulnerability affects all versions up to and including 1.2. No patch or official fix has been documented at this time.

An attacker with contributor-level or higher access can exploit this vulnerability to inject persistent malicious scripts into pages using the 'ragic' shortcode. These scripts execute in the browsers of users who visit the compromised pages, potentially leading to information disclosure or session hijacking. The vulnerability does not affect system availability. The CVSS 3.1 base score of 6.4 reflects a medium impact with low attack complexity and no user interaction required.

No official patch or remediation has been confirmed at this time. Users of the Ragic Shortcode plugin should monitor the vendor's advisory channels for updates and apply any forthcoming patches promptly. Until a fix is available, restrict contributor-level access to trusted users only and consider disabling or removing the plugin if feasible to reduce exposure.
