WordPress · Accordion Slider · CVE-2024-9582
**Name of the Vulnerable Software and Affected Versions**
Accordion Slider plugin for WordPress versions up to, and including, 1.9.11
**Description**
The issue is related to Stored Cross-Site Scripting due to insufficient input sanitization and output escaping in the `html` attribute of an accordion slider. This allows authenticated attackers with Contributor-level access and above to inject arbitrary web scripts in pages, which will execute when a user accesses the injected page. Successful exploitation by Contributor-level users requires an Administrator-level user to provide access to the plugin's admin area via the `Access` plugin setting.
**Recommendations**
For versions up to, and including, 1.9.11, update to a version that includes the necessary input sanitization and output escaping fixes to prevent Stored Cross-Site Scripting attacks.
As a temporary workaround, consider restricting access to the plugin's admin area and limiting the ability of Contributor-level users to inject arbitrary web scripts.
