CVE-2025-62910 identifies a stored Cross-site Scripting (XSS) vulnerability in the deshine Video Gallery plugin by Huzzaz, versions up to and including 10.5. The vulnerability stems from improper neutralization of user-supplied input during the generation of web pages, which allows attackers to inject malicious JavaScript code that is stored persistently on the server. When other users visit the affected pages, the malicious scripts execute in their browsers under the context of the vulnerable website. This can lead to a range of attacks including session hijacking, theft of sensitive information such as authentication tokens or cookies, defacement, or distribution of malware. The vulnerability is classified as stored XSS, which is more dangerous than reflected XSS because the malicious payload is permanently stored and served to multiple users. No CVSS score has been assigned yet, and no known exploits have been reported in the wild, but the risk remains significant due to the widespread use of web galleries and the potential for exploitation. The vulnerability affects all versions up to 10.5, with no patch links currently available, indicating that users should monitor vendor updates closely. The vulnerability was reserved and published in late October 2025 by Patchstack, a recognized vulnerability database. The absence of authentication requirements and the ability to exploit the vulnerability by simply visiting a compromised page increase the risk profile. Stored XSS vulnerabilities are often leveraged in targeted attacks against organizations with high-value web assets or sensitive user bases.

For European organizations, this vulnerability poses a significant risk to web applications that utilize the deshine Video Gallery plugin. Exploitation could lead to unauthorized access to user sessions, theft of credentials, and potential compromise of user data, impacting confidentiality and integrity. The stored nature of the XSS means that once an attacker injects malicious code, all visitors to the affected page are exposed, potentially amplifying the attack's reach. This could damage organizational reputation, lead to regulatory non-compliance under GDPR due to data breaches, and cause operational disruptions if attackers leverage the vulnerability to deploy further malware or conduct phishing campaigns. Organizations in sectors such as e-commerce, media, education, and government, which often use video galleries for content delivery, are particularly vulnerable. The lack of a current patch increases the window of exposure, necessitating immediate mitigation efforts. Additionally, the vulnerability could be used as a foothold for more advanced attacks within the network, especially if combined with other vulnerabilities or social engineering tactics.

1. Monitor the vendor's official channels for patches addressing CVE-2025-62910 and apply them promptly once available. 2. Implement strict input validation on all user-supplied data fields within the Video Gallery plugin to prevent malicious script injection. 3. Employ output encoding/escaping techniques when rendering user input in web pages to neutralize potentially harmful scripts. 4. Deploy Content Security Policy (CSP) headers to restrict the execution of unauthorized scripts and reduce the impact of XSS attacks. 5. Conduct regular security audits and penetration testing focused on web application vulnerabilities, including XSS. 6. Educate web developers and administrators about secure coding practices related to input handling and output generation. 7. Consider temporary disabling or replacing the Video Gallery plugin with a more secure alternative if immediate patching is not feasible. 8. Use Web Application Firewalls (WAFs) with rules tuned to detect and block XSS payloads targeting the affected plugin. 9. Implement robust logging and monitoring to detect suspicious activities indicative of exploitation attempts. 10. Ensure that user sessions have appropriate security controls such as HttpOnly and Secure flags on cookies to mitigate session hijacking risks.
