CVE-2025-5752 identifies a stored cross-site scripting vulnerability in the gopiplus Vertical scroll image slideshow gallery plugin for WordPress, impacting all versions up to and including 11.1. The vulnerability stems from improper neutralization of input during web page generation, specifically insufficient sanitization and escaping of the 'width' parameter. Authenticated attackers with Contributor-level access or higher can exploit this flaw by injecting arbitrary JavaScript code into pages via the vulnerable parameter. Because the malicious script is stored persistently, it executes in the context of any user who views the infected page, potentially compromising user sessions, stealing cookies, or performing actions on behalf of users. The attack vector is network-based, requiring only authenticated access with low complexity and no user interaction, increasing the risk in environments where contributor roles are assigned liberally. The vulnerability affects the confidentiality and integrity of data but does not impact availability. Although no public exploits are currently known, the widespread use of WordPress and this plugin increases the risk of future exploitation. The CVSS 3.1 score of 6.4 reflects a medium severity rating, emphasizing the need for timely remediation. The vulnerability was publicly disclosed in July 2025, with no official patches yet available, highlighting the importance of interim mitigations.

The primary impact of CVE-2025-5752 is the compromise of confidentiality and integrity within affected WordPress sites. Exploitation allows attackers to execute arbitrary scripts in the context of site visitors, potentially leading to session hijacking, credential theft, defacement, or distribution of malware. Since the vulnerability requires authenticated access at the Contributor level or higher, attackers who gain or already have such access can leverage this flaw to escalate their influence and affect other users, including administrators. This can undermine trust in the affected websites, cause reputational damage, and lead to data breaches. Organizations relying on the gopiplus plugin for image slideshows may face targeted attacks, especially if they have a large user base or handle sensitive information. The vulnerability does not affect availability directly but can facilitate further attacks that may disrupt services. The medium CVSS score reflects moderate risk, but the ease of exploitation by authenticated users and the persistent nature of stored XSS increase the threat level in environments with multiple contributors.

To mitigate CVE-2025-5752, organizations should first verify if they use the gopiplus Vertical scroll image slideshow gallery plugin and identify the version in use. Since no official patch is currently available, immediate steps include restricting Contributor-level access to trusted users only and reviewing user roles to minimize unnecessary privileges. Implementing Web Application Firewall (WAF) rules to detect and block malicious payloads targeting the 'width' parameter can provide interim protection. Site administrators should enable strict input validation and output encoding in custom code or through security plugins to prevent script injection. Regularly monitoring logs and user activity for suspicious behavior related to content editing is essential. Additionally, consider disabling or replacing the vulnerable plugin with a secure alternative until an official patch is released. Educating content contributors about safe input practices and the risks of XSS can further reduce exploitation chances. Once a patch becomes available, prioritize its deployment to fully remediate the vulnerability.
