Name of the Vulnerable Software and Affected Versions Slidorion versions up to and including 1.0.2

Description The Slidorion plugin for WordPress is susceptible to Stored Cross-Site Scripting through admin settings. Insufficient input sanitization and output escaping allow authenticated attackers with administrator-level permissions or higher to inject arbitrary web scripts into pages. These scripts will execute when a user accesses the injected page. This issue only impacts multi-site installations and those where unfiltered html has been disabled.

Recommendations Update Slidorion to a version later than 1.0.2.
