Description
The WP Flot plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the plugin's 'linechart' shortcode in all versions up to, and including, 0.2.2 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.

Impact: Stored Cross‑Site Scripting via shortcode attribute enabled by contributor‑level access
Action: Patch plugin
AI Analysis

Impact

The WP Flot plugin fails to properly sanitize and escape user‑supplied attributes in its 'linechart' shortcode. This lets an authenticated user with contributor or higher privileges inject arbitrary JavaScript that is persisted and executed whenever a page containing the shortcode is viewed. The injected payload can read cookies, deface the site, or perform other client‑side attacks against visitors.

Affected Systems

The vulnerability is present in all releases of the WP Flot WordPress plugin through version 0.2.2. Site owners using any of these affected versions are at risk until the plugin is upgraded.

Risk and Exploitability

The CVSS score of 6.4 rates this as a medium severity issue; the EPSS score of less than 1% indicates a low likelihood of exploitation, and the vulnerability is not listed in the CISA KEV catalog. Attackers who can obtain contributor or higher access to the WordPress site can exploit the stored XSS vector by placing a malicious shortcode attribute, with the injected script running in the browsers of all users who load the affected page.

Remediation

No vendor fix or workaround currently provided.

OpenCVE Recommended Actions

  • Update the WP Flot plugin to version 0.2.3 or later.
  • If an immediate update is not possible, restrict contributor‑level users from adding the 'linechart' shortcode or remove contributor access to pages that use it.
  • Disable or delete the shortcode from public pages until a secure plugin version is available.
