CVE-2025-14032 identifies a stored Cross-Site Scripting (XSS) vulnerability in the Bold Timeline Lite plugin for WordPress, specifically in all versions up to and including 1.2.7. The vulnerability exists due to improper neutralization of input during web page generation (CWE-79). The flaw is located in the handling of the 'title' parameter within the 'bold_timeline_group' shortcode, where insufficient input sanitization and output escaping allow an authenticated user with Contributor-level privileges or higher to inject arbitrary JavaScript code. This malicious script is stored persistently and executed in the context of any user who accesses the affected page, potentially compromising user sessions, stealing cookies, or performing unauthorized actions on behalf of users. The attack vector requires authentication but no user interaction to trigger the payload once the page is accessed. The vulnerability has a CVSS v3.1 base score of 6.4, reflecting a medium severity level with network attack vector, low attack complexity, and privileges required. The scope is changed because the vulnerability affects other users beyond the attacker. No patches or known exploits are currently reported, but the risk remains significant due to the widespread use of WordPress and the plugin in question. The vulnerability highlights the importance of proper input validation and output encoding in web applications, especially those allowing user-generated content or multiple contributors.

For European organizations, the impact of this vulnerability can be substantial, particularly for those relying on WordPress sites with multiple contributors or editors. Exploitation could lead to session hijacking, theft of sensitive user information, unauthorized actions performed under the victim's credentials, and potential defacement or redirection attacks. This can damage organizational reputation, lead to data breaches, and cause compliance issues under GDPR due to unauthorized data exposure. The medium severity score indicates that while the vulnerability is not trivial, it requires authenticated access, limiting the attack surface to insiders or compromised accounts. However, many organizations have contributors with such access, increasing risk. The persistent nature of the stored XSS means that once injected, the malicious code can affect all users visiting the compromised pages, amplifying the impact. Additionally, automated tools or bots scanning for such vulnerabilities could facilitate exploitation. The lack of a patch at the time of disclosure increases exposure duration, necessitating immediate mitigation efforts.

1. Monitor for and apply official patches or updates from BoldThemes as soon as they become available to remediate the vulnerability. 2. Until a patch is released, restrict Contributor-level and higher access to trusted users only, minimizing the risk of malicious input injection. 3. Implement Web Application Firewall (WAF) rules to detect and block suspicious script injection attempts targeting the 'title' parameter or the 'bold_timeline_group' shortcode. 4. Employ Content Security Policy (CSP) headers to limit the execution of unauthorized scripts on affected pages. 5. Conduct manual or automated code reviews and sanitize inputs by applying strict whitelist validation and output encoding for any user-generated content in the plugin's shortcode parameters. 6. Educate content contributors about the risks of injecting untrusted content and enforce strong authentication and session management controls to prevent account compromise. 7. Regularly audit WordPress plugins and themes for vulnerabilities and remove or replace those no longer maintained or secure. 8. Use security plugins that can detect and alert on suspicious activities related to XSS or other injection attacks.
