Summary

The SKT Skill Bar plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the `chart_size` attribute of the `skillwrapper` shortcode in all versions up to and including 2.6 due to insufficient input sanitization and output escaping. The attribute is concatenated directly into an inline `<style>` block, allowing authenticated attackers with Contributor-level access and above to inject arbitrary web scripts.

Risk Assessment

Injected scripts can execute in users' browsers, potentially leading to session theft, account takeover, or malware distribution.

Recommendation

Update the SKT Skill Bar plugin to the latest version if available. Restrict content editing access to trusted users and consider using a web application firewall.

Original NVD description (English source)

The SKT Skill Bar plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the `chart_size` attribute of the `skillwrapper` shortcode in all versions up to, and including, 2.6. This is due to insufficient input sanitization and output escaping on the `chart_size` attribute, which is concatenated directly into an inline `<style>` block. 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.
