CVE-2025-69316 is a reflected Cross-site Scripting (XSS) vulnerability identified in the RealMag777 TableOn plugin, specifically in the posts-table-filterable component. This vulnerability stems from improper neutralization of input during web page generation, which allows an attacker to inject malicious JavaScript code into web pages viewed by other users. The affected versions include all releases up to and including 1.0.4.2. When a victim interacts with a crafted URL or input containing malicious payloads, the injected script executes in their browser context, potentially leading to session hijacking, defacement, or redirection to malicious sites. The vulnerability is exploitable remotely over the network without requiring authentication, but it does require user interaction to trigger the malicious script. The CVSS v3.1 base score is 6.1, reflecting a medium severity level, with attack vector as network (AV:N), low attack complexity (AC:L), no privileges required (PR:N), user interaction required (UI:R), scope changed (S:C), and impacts on confidentiality and integrity but not availability (C:L/I:L/A:N). No patches or known exploits are currently reported, but the vulnerability is publicly disclosed and should be addressed promptly. The reflected XSS nature means the attack payload is not stored on the server but reflected in responses, making phishing or social engineering a likely attack vector.

For European organizations, the impact of CVE-2025-69316 can be significant, especially for those running websites or web applications that utilize the TableOn plugin. Successful exploitation can lead to theft of session cookies, enabling attackers to impersonate legitimate users, potentially accessing sensitive information or performing unauthorized actions. It can also facilitate defacement or redirection attacks, damaging organizational reputation and user trust. While the vulnerability does not affect availability, the compromise of confidentiality and integrity can have regulatory implications under GDPR, particularly if personal data is exposed or manipulated. Organizations with high web traffic and user interaction are at greater risk. Additionally, sectors such as e-commerce, government portals, and online services that rely on WordPress plugins for content management are particularly vulnerable. The lack of authentication requirement lowers the barrier for attackers, increasing the likelihood of exploitation if unmitigated.

1. Apply patches or updates from RealMag777 as soon as they become available to address this vulnerability. 2. Implement strict input validation and output encoding on all user-supplied data to neutralize potentially malicious scripts before rendering. 3. Deploy Content Security Policy (CSP) headers to restrict the execution of unauthorized scripts and reduce the impact of XSS attacks. 4. Use Web Application Firewalls (WAFs) configured to detect and block reflected XSS payloads targeting the TableOn plugin. 5. Educate users and administrators about phishing risks and the importance of not clicking suspicious links. 6. Regularly audit and monitor web application logs for unusual activities that may indicate exploitation attempts. 7. Consider disabling or replacing the TableOn plugin if immediate patching is not feasible, especially on high-risk systems. 8. Employ security headers such as X-XSS-Protection and HttpOnly cookies to provide additional layers of defense.
