Accordion Slider <= 1.9.11 - Authenticted (Contributor+) Stored Cross-Site Scripting via HTML Attribute
Get instant alerts when new vulnerabilities affect Accordion Slider - before attackers find them.
The Accordion Slider plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the ‘html’ attribute of an accordion slider in all versions up to, and including, 1.9.11 due to insufficient input sanitization and output escaping. 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. NOTE: 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, which is restricted to administrators by default.
No remediation guidance has been written for this CVE yet. What the record does show:
SSVC signals action urgency (what to patch first), separate from CVSS which measures severity.
