MEDIUM 6.4

DescriptionCVE.org

The Accordions plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the Accordion body field in all versions up to, and including, 2.3.23 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with Custom-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.

AnalysisAI

Stored Cross-Site Scripting in the Accordions plugin for WordPress (all versions through 2.3.23) enables authenticated attackers holding Custom-level roles or higher to permanently embed malicious JavaScript into Accordion body fields. The injected scripts execute in the browser of any user who subsequently visits an affected page, enabling session token theft, credential harvesting, or drive-by malware delivery within the WordPress site context. No public exploit has been identified at time of analysis, though an upstream fix commit is available in the plugin Trac repository.

Technical ContextAI

The vulnerability resides in the Accordions WordPress plugin, a UI component plugin that renders collapsible content panels on WordPress pages. CWE-79 (Improper Neutralization of Input During Web Page Generation - Cross-Site Scripting) identifies the root cause: user-supplied input entered into the Accordion body field is neither adequately sanitized on ingestion nor properly escaped during output rendering. This allows HTML and JavaScript payloads to persist in the WordPress database and be reflected verbatim into rendered page HTML for all subsequent visitors. The CVSS scope value S:C (Changed) reflects that impact crosses the security boundary from the authenticated plugin editor context into the browsers of arbitrary unauthenticated site visitors. The AV:N/AC:L combination confirms the vulnerability is exploitable over the network with no special preconditions beyond holding a low-privilege authenticated session.

RemediationAI

The primary remediation is to update the Accordions plugin to a version beyond 2.3.23. An upstream fix has been committed to the plugin repository as documented at https://plugins.trac.wordpress.org/changeset/3564090/; however, the exact patched release version number is not independently confirmed from available data - administrators should verify the current published version in the WordPress Plugin Directory before updating to ensure the fix commit has been included in a tagged release. As a compensating control where immediate patching is not feasible, restrict the creation of Custom-level and above WordPress accounts to fully trusted individuals only, since exploitation requires authenticated access at that privilege level - note this does not mitigate risk from insider threats or compromised existing accounts. A Web Application Firewall rule targeting script injection patterns in accordion body input fields can reduce exposure, though WAF bypass techniques exist and this should not substitute for patching.
