Overview
A stored Cross-Site Scripting (XSS) vulnerability has been identified in the Accordion Slider WordPress plugin. This vulnerability, tracked as CVE-2025-66092, allows an attacker to inject malicious JavaScript code into the plugin’s settings or content, which is then executed in the browsers of other users accessing the affected website. This vulnerability affects versions of Accordion Slider up to and including 1.9.13.
Technical Details
CVE-2025-66092 details an Improper Neutralization of Input During Web Page Generation (‘Cross-site Scripting’) vulnerability. The Accordion Slider plugin fails to properly sanitize user-supplied input when handling data related to slider titles, descriptions, or other configurable fields. An attacker with sufficient privileges (e.g., an administrator or editor, depending on plugin configuration) can inject malicious JavaScript code into these fields. This code is then stored in the WordPress database and executed whenever a user views a page containing the compromised accordion slider.
The injected script can perform a variety of malicious actions, including:
- Redirecting users to phishing websites.
- Stealing user cookies and session information.
- Modifying the website’s content.
- Defacing the website.
- Compromising administrator accounts.
CVSS Analysis
Currently, the CVE entry for CVE-2025-66092 does not provide a CVSS score or severity rating. This is not uncommon in the initial stages of vulnerability disclosure. However, given the nature of stored XSS vulnerabilities, which can have a significant impact on website security and user privacy, it is generally considered a high-risk issue. The absence of a CVSS score should not diminish the urgency of addressing this vulnerability.
Possible Impact
The impact of a successful XSS attack via CVE-2025-66092 can be significant. Attackers can gain control of user accounts, including administrator accounts, leading to complete website compromise. Sensitive data can be stolen, and the website can be used to distribute malware or spread misinformation. The damage to a website’s reputation can also be substantial.
Mitigation and Patch Steps
The recommended mitigation is to immediately update the Accordion Slider plugin to the latest version if a newer version is available. Check the WordPress plugin repository or the plugin developer’s website for updates.
If an update is not yet available, consider the following temporary mitigation strategies:
- Disable the Accordion Slider plugin: Temporarily disabling the plugin will prevent the vulnerability from being exploited.
- Review user roles and permissions: Ensure that only trusted users have administrative or editing privileges that allow them to modify plugin settings.
- Implement a web application firewall (WAF): A WAF can help to detect and block XSS attacks.
- Monitor website activity: Keep a close eye on your website’s logs for any suspicious activity.
It is highly recommended to check the plugin developer’s website and WordPress support forums for updates and official patches.
