CVE-2025-62910 is a stored Cross-site Scripting (XSS) vulnerability identified in the deshine Video Gallery plugin by Huzzaz, affecting all versions up to and including 10.5. The vulnerability stems from improper neutralization of input during web page generation, which allows malicious actors to inject and store arbitrary JavaScript code within the plugin's data fields. When a victim user accesses the affected page, the malicious script executes in their browser context. The CVSS 3.1 vector (AV:N/AC:L/PR:L/UI:R/S:C/C:L/I:L/A:N) indicates that the attack can be performed remotely over the network with low attack complexity, requires the attacker to have some privileges (likely a registered user), and requires user interaction (e.g., a victim visiting a maliciously crafted page). The scope is changed, meaning the vulnerability affects resources beyond the initially vulnerable component. The impact includes limited confidentiality and integrity loss, such as session hijacking, defacement, or unauthorized actions performed on behalf of the user, but does not affect system availability. No known public exploits have been reported yet, and no official patches were linked at the time of disclosure. This vulnerability is typical of web applications that fail to properly sanitize or encode user input before rendering it in HTML pages, leading to persistent XSS attacks.

For European organizations, especially those operating public-facing websites using the deshine Video Gallery plugin, this vulnerability poses a risk of client-side script injection that can compromise user sessions, steal sensitive information, or perform unauthorized actions on behalf of users. This can lead to reputational damage, regulatory non-compliance (e.g., GDPR breaches if personal data is exposed), and potential financial losses. Since the vulnerability requires some level of attacker privilege and user interaction, the risk is somewhat mitigated but still significant for websites with large user bases or where users have elevated privileges. Attackers could leverage this to target employees or customers, potentially gaining footholds for further attacks. The lack of known exploits reduces immediate risk but does not eliminate it, as attackers may develop exploits post-disclosure. Organizations in sectors like media, entertainment, education, and e-commerce using this plugin are particularly vulnerable.

1. Monitor the vendor’s official channels for patches and apply updates to the deshine Video Gallery plugin promptly once available. 2. In the interim, restrict user privileges to minimize the ability of untrusted users to submit content that could be exploited. 3. Implement strict input validation and output encoding on all user-supplied data fields related to the plugin to neutralize malicious scripts. 4. Employ Content Security Policy (CSP) headers to limit the execution of unauthorized scripts in browsers. 5. Conduct regular security audits and penetration testing focusing on web application input handling. 6. Educate users and administrators about the risks of clicking on suspicious links or content. 7. Consider disabling or replacing the plugin if immediate patching is not feasible, especially on high-risk sites. 8. Monitor web server and application logs for unusual activity indicative of attempted exploitation.
