CVE-2025-62910 identifies a stored Cross-site Scripting (XSS) vulnerability in the deshine Video Gallery plugin by Huzzaz, a tool used to manage and display video content on websites. The vulnerability stems from improper neutralization of user-supplied input during web page generation, which allows attackers to inject malicious scripts that are stored and later executed in the browsers of users who view the affected pages. This stored XSS can be exploited by an attacker with at least limited privileges (as indicated by the CVSS vector requiring privileges but no administrative rights) and requires user interaction, such as a victim visiting a crafted page or interacting with malicious content. The vulnerability impacts confidentiality and integrity by enabling session hijacking, theft of sensitive information, or unauthorized actions performed on behalf of the victim user. The CVSS score of 5.4 reflects a medium severity level, considering the network attack vector, low attack complexity, and the requirement for privileges and user interaction. No known exploits are currently active in the wild, but the vulnerability affects all versions of the plugin up to and including 10.5. The lack of available patches at the time of publication necessitates proactive mitigation. The vulnerability is particularly relevant for websites that rely on the deshine Video Gallery plugin to manage video content, which may be common in various sectors including media, education, and corporate communications.

For European organizations, exploitation of this vulnerability could lead to unauthorized disclosure of user session tokens, enabling attackers to impersonate legitimate users and access sensitive information or perform unauthorized actions. This can damage organizational reputation, lead to data breaches, and cause regulatory compliance issues under GDPR due to exposure of personal data. Since the vulnerability requires some level of user privileges and interaction, internal users or authenticated customers could be targeted, increasing the risk in environments with multiple user roles. The integrity of website content could also be compromised, potentially leading to misinformation or defacement. Given the widespread use of WordPress and related plugins in Europe, organizations in sectors such as media, education, and e-commerce are particularly at risk. The absence of known exploits reduces immediate risk but does not eliminate the threat, especially as attackers often develop exploits after public disclosure.

Organizations should monitor the vendor’s communications for patches and apply them promptly once available. In the interim, implement strict input validation and output encoding on all user-supplied data fields related to the Video Gallery plugin to prevent script injection. Employ Content Security Policy (CSP) headers to restrict the execution of unauthorized scripts. Limit user privileges to the minimum necessary to reduce the risk of exploitation by low-privilege attackers. Conduct regular security audits and scanning for XSS vulnerabilities in web applications. Educate users about the risks of interacting with suspicious content and monitor logs for unusual activities related to the plugin. Consider disabling or replacing the plugin if immediate patching is not feasible. Additionally, web application firewalls (WAFs) can be configured to detect and block common XSS attack patterns targeting this plugin.
