CVE-2025-24533 is a Cross-Site Request Forgery (CSRF) vulnerability identified in the Responsive Slider by MetaSlider WordPress plugin, affecting all versions up to 3.92.0. CSRF vulnerabilities occur when a web application does not properly verify that state-changing requests originate from legitimate users, allowing attackers to craft malicious requests that execute actions on behalf of authenticated users without their knowledge. In this case, the MetaSlider plugin fails to implement adequate anti-CSRF tokens or similar protections on sensitive operations, enabling attackers to exploit this flaw by enticing logged-in administrators or users with sufficient privileges to visit a malicious website. Once triggered, the attacker can manipulate slider configurations or other plugin settings, potentially defacing the website, disrupting user experience, or injecting malicious content. The vulnerability does not require the attacker to have direct access or credentials, but the victim must be authenticated on the target site. No public exploit code or active exploitation has been reported yet, but the vulnerability is publicly disclosed and documented in the CVE database. The absence of a CVSS score necessitates a severity assessment based on impact and exploitability factors. Given the widespread use of WordPress and the popularity of MetaSlider, this vulnerability could affect a broad range of websites globally, especially those that have not updated to patched versions or implemented compensating controls.

The primary impact of this CSRF vulnerability is unauthorized modification of website content or plugin settings by attackers leveraging authenticated users' sessions. This can lead to website defacement, disruption of user experience, or injection of malicious content, potentially damaging the organization's reputation and user trust. For e-commerce or business-critical sites, such unauthorized changes may result in financial loss or operational downtime. Since the vulnerability requires the victim to be authenticated, the scope is limited to sites with logged-in users who have sufficient privileges, typically administrators or editors. However, given the ease of exploitation through social engineering (e.g., phishing links), the risk remains significant. There is no indication of direct data confidentiality compromise or remote code execution, but integrity and availability of the website are at risk. Organizations worldwide using this plugin without patches are vulnerable, especially those with high traffic or strategic importance.

Organizations should immediately update the Responsive Slider by MetaSlider plugin to the latest version once a patch is released. Until a patch is available, implement the following mitigations: 1) Employ Web Application Firewalls (WAFs) with rules to detect and block CSRF attack patterns targeting the plugin endpoints. 2) Restrict administrative access to trusted IP addresses or VPNs to reduce exposure. 3) Educate users with administrative privileges about the risks of clicking untrusted links while logged into the WordPress dashboard. 4) Use security plugins that add CSRF protections or nonce verification for plugin actions. 5) Regularly audit and monitor logs for suspicious activity related to slider configuration changes. 6) Disable or remove the MetaSlider plugin if it is not essential to reduce attack surface. 7) Enforce least privilege principles by limiting the number of users with administrative rights. These steps will help mitigate risk until an official patch is applied.
