CVE-2025-14796 is a stored Cross-Site Scripting (XSS) vulnerability identified in the My Album Gallery plugin for WordPress, versions up to and including 1.0.4. The vulnerability stems from improper neutralization of input during web page generation, specifically insufficient sanitization and escaping of the 'attachment->title' attribute used for image titles. Authenticated users with Author-level privileges or higher can exploit this flaw by injecting arbitrary JavaScript code into image titles. Because the malicious script is stored persistently, it executes whenever any user accesses the affected page, potentially compromising user sessions or enabling unauthorized actions. The vulnerability does not require user interaction beyond viewing the page and does not affect availability but impacts confidentiality and integrity by enabling theft of cookies, credentials, or manipulation of page content. The CVSS 3.1 score of 6.4 reflects the medium severity, with network attack vector, low attack complexity, and privileges required. No public exploits have been reported yet, but the vulnerability poses a risk to WordPress sites using this plugin, especially those with multiple users and elevated privilege roles. The lack of patches at the time of reporting necessitates immediate mitigation steps to reduce risk.

For European organizations, this vulnerability can lead to unauthorized access to user sessions, theft of sensitive information such as authentication cookies, and potential privilege escalation if attackers leverage the XSS to perform actions on behalf of other users. Organizations relying on WordPress sites with the My Album Gallery plugin are at risk of reputational damage, data breaches, and compliance violations under GDPR if personal data is compromised. The impact is heightened in environments where multiple users have Author-level or higher access, such as collaborative publishing platforms or intranet sites. Although availability is not directly affected, the integrity and confidentiality of user data and site content are at risk, potentially leading to further exploitation or lateral movement within the organization’s web infrastructure.

1. Immediately restrict Author-level and higher privileges to trusted users only, minimizing the number of users who can exploit this vulnerability. 2. Monitor and audit image titles and other user-generated content for suspicious scripts or anomalies. 3. Implement Web Application Firewall (WAF) rules to detect and block common XSS payloads targeting the 'attachment->title' attribute. 4. Apply strict Content Security Policy (CSP) headers to limit the execution of unauthorized scripts on affected pages. 5. Regularly update the My Album Gallery plugin and WordPress core once patches addressing this vulnerability are released. 6. Employ additional input validation and output encoding at the application level to sanitize user inputs and escape outputs properly. 7. Educate site administrators and content creators about the risks of XSS and safe content practices. 8. Conduct periodic security assessments and penetration testing focusing on user input handling and privilege management.
