CVE-2025-23640 is a high-severity Cross-Site Request Forgery (CSRF) vulnerability affecting the Nazmul Ahsan Rename Author Slug plugin, specifically versions up to 1.2.0. This vulnerability allows attackers to exploit stored cross-site scripting (XSS), putting user data and web application integrity at risk.
With a CVSS score of 7.1, this vulnerability is classified as high severity, indicating a significant risk to organizations utilizing the affected plugin. The attack vector is network-based, requiring low attack complexity and no privileges, although user interaction is required to trigger the vulnerability. The potential impacts include low confidentiality, integrity, and availability.
Organizations using the Rename Author Slug plugin should prioritize remediation efforts, particularly since this vulnerability could allow attackers to execute scripts in the context of an authenticated user, thereby compromising sensitive information.
The vulnerability was published on January 16, 2025, and is currently marked as deferred. However, organizations are encouraged to patch this vulnerability promptly to mitigate potential risks.
Vulnerability Details
This vulnerability allows for stored XSS due to improper handling of CSRF tokens in the Rename Author Slug plugin, affecting versions from n/a to 1.2.0. The official CVE description indicates that the vulnerability stems from the plugin's failure to validate CSRF tokens effectively.
The CVSS score of 7.1 indicates high severity, with the following metrics: attack vector (network), attack complexity (low), privileges required (none), user interaction (required), and impacts on confidentiality, integrity, and availability being classified as low.
The vulnerability is categorized under CWE-352, which pertains to Cross-Site Request Forgery. This classification highlights the need for robust CSRF protections in web applications.
Technical Analysis
The root cause of CVE-2025-23640 is the inadequate validation of CSRF tokens, which allows attackers to execute unauthorized actions on behalf of authenticated users. The primary attack vector is network-based, meaning that attackers can exploit this vulnerability remotely.
The attack complexity is classified as low, indicating that minimal skill is needed to exploit the vulnerability. No privileges are required, but user interaction is necessary to trigger the stored XSS payload.
The impact on confidentiality, integrity, and availability is categorized as low, meaning that while the exploit may not cause complete system compromise, it could lead to unauthorized data exposure or manipulation.
Risk & Impact Analysis
Risk to organizations includes the potential for unauthorized access to sensitive user data and the ability to manipulate content. As the vulnerability is currently classified as high severity, organizations should prioritize patching immediately.
The blast radius of this vulnerability could be significant, affecting all users of the affected plugin. Given the nature of CSRF and stored XSS attacks, the urgency to address this vulnerability is high to prevent data breaches or reputational damage.
Organizations should assess their exposure and implement necessary patches as soon as possible, particularly since the vulnerability is already in the public domain.
