CVE-2025-7687 is a Cross-Site Request Forgery (CSRF) vulnerability affecting the Latest Post Accordian Slider plugin for WordPress, developed by anop-goswami. This vulnerability exists in all versions up to and including 1.3 due to missing or incorrect nonce validation on the 'lpaccordian' page. Nonces in WordPress are security tokens used to verify that requests are intentional and originate from authenticated users. The absence or improper implementation of nonce validation allows an attacker to craft a malicious request that, when executed by an authenticated site administrator (e.g., by clicking a link or visiting a crafted webpage), can update plugin settings and inject malicious web scripts. This can lead to unauthorized changes in the plugin’s behavior and potentially enable further attacks such as persistent cross-site scripting (XSS). The CVSS v3.1 base score is 6.1 (medium severity), reflecting that the attack requires no privileges but does require user interaction (an administrator clicking a malicious link). The vulnerability impacts confidentiality and integrity but not availability, and the scope is changed as the attacker can affect resources beyond their own privileges by leveraging the administrator’s session. No known exploits are currently reported in the wild, and no patches have been linked yet. This vulnerability is categorized under CWE-352, which is a common web application security weakness related to CSRF attacks.

For European organizations using WordPress websites with the Latest Post Accordian Slider plugin, this vulnerability poses a moderate risk. Successful exploitation could allow attackers to alter plugin settings and inject malicious scripts, potentially leading to unauthorized content changes, defacement, or the delivery of malware to site visitors. This undermines the confidentiality and integrity of the affected websites and could damage organizational reputation, especially for entities relying on their web presence for customer engagement or e-commerce. Since the attack requires tricking an administrator into clicking a link, organizations with less stringent security awareness training or lacking multi-factor authentication for admin accounts are more vulnerable. Additionally, injected scripts could be used to steal session cookies or credentials, leading to further compromise. The impact is heightened for organizations handling sensitive customer data or operating critical services online. However, the lack of known active exploitation reduces immediate risk, though the medium severity score indicates that timely mitigation is important to prevent future attacks.

European organizations should immediately audit their WordPress installations to identify the presence of the Latest Post Accordian Slider plugin and verify the version in use. Until an official patch is released, administrators should consider disabling or removing the plugin to eliminate exposure. If removal is not feasible, restricting administrative access to trusted IP addresses and enforcing strong multi-factor authentication can reduce the risk of exploitation. Additionally, organizations should implement Content Security Policy (CSP) headers to limit the impact of injected scripts and conduct security awareness training to educate administrators about the risks of clicking unsolicited links. Monitoring web server logs for unusual POST requests to the 'lpaccordian' page and anomalous changes in plugin settings can help detect attempted exploitation. Once a patch is available, prompt application is critical. Web application firewalls (WAFs) can also be configured to detect and block suspicious requests targeting the vulnerable endpoints. Regular backups of website data and configurations will facilitate recovery in case of compromise.
