CVE-2025-22517 identifies a stored Cross-site Scripting (XSS) vulnerability in the Ben Huson List Pages at Depth plugin, specifically versions up to and including 1.5. The vulnerability stems from improper neutralization of user-supplied input during the generation of web pages, allowing malicious scripts to be injected and persist on affected pages. Stored XSS is particularly dangerous because the malicious payload is saved on the server and served to all users visiting the compromised page, increasing the attack surface. Attackers can exploit this flaw to execute arbitrary JavaScript in the context of users’ browsers, potentially leading to session hijacking, credential theft, defacement, or distribution of malware. The vulnerability does not require authentication or user interaction beyond visiting the infected page, which lowers the barrier for exploitation. Although no public exploits have been reported yet, the presence of this vulnerability in a widely used plugin component poses a significant risk. The lack of a CVSS score suggests the need for a manual severity assessment. The vulnerability affects all versions up to 1.5, and no official patches or fixes have been linked yet, indicating that users should be cautious and monitor for updates. The plugin’s usage in content management systems, particularly WordPress, means that many websites could be exposed if they have not updated or mitigated the issue.

The impact of CVE-2025-22517 is substantial for organizations running websites with the vulnerable Ben Huson List Pages at Depth plugin. Successful exploitation can lead to the execution of arbitrary scripts in the browsers of site visitors, compromising user confidentiality and integrity. This can result in session hijacking, theft of sensitive information such as cookies or credentials, unauthorized actions performed on behalf of users, website defacement, and the spread of malware. The stored nature of the XSS means that all visitors to the infected page are at risk, amplifying the potential damage. For organizations, this can lead to reputational damage, loss of customer trust, regulatory penalties if personal data is compromised, and increased operational costs to remediate the issue. The ease of exploitation without authentication or user interaction further elevates the threat level. Additionally, attackers could leverage this vulnerability as a foothold for more advanced attacks or lateral movement within a network if administrative users are targeted.

To mitigate CVE-2025-22517, organizations should: 1) Monitor for and apply any official patches or updates released by the vendor promptly once available. 2) Implement strict input validation and sanitization on all user-supplied data to prevent malicious script injection. 3) Employ robust output encoding techniques to neutralize any potentially harmful content before rendering it in web pages. 4) Utilize Content Security Policy (CSP) headers to restrict the execution of unauthorized scripts and reduce the impact of XSS attacks. 5) Conduct regular security audits and penetration testing focused on web application vulnerabilities, including XSS. 6) Consider temporarily disabling or replacing the vulnerable plugin if immediate patching is not possible. 7) Educate web administrators and developers on secure coding practices to prevent similar vulnerabilities. 8) Implement web application firewalls (WAFs) with rules designed to detect and block XSS payloads. These measures collectively reduce the risk of exploitation and limit potential damage.
