CVE-2025-14109 identifies a stored cross-site scripting vulnerability in the AH Shortcodes plugin for WordPress, specifically through the 'column' shortcode attribute. This vulnerability exists in all versions up to and including 1.0.2 due to insufficient sanitization of user-supplied input and lack of proper output escaping before rendering content on web pages. An attacker with authenticated access at the Contributor level or higher can craft malicious shortcode attributes that embed arbitrary JavaScript code. When any user accesses a page containing the injected shortcode, the malicious script executes in their browser context, potentially compromising session tokens, redirecting users, or performing actions on behalf of the victim. The vulnerability does not require user interaction beyond visiting the affected page and does not require elevated privileges beyond Contributor access. The CVSS 3.1 vector (AV:N/AC:L/PR:L/UI:N/S:C/C:L/I:L/A:N) reflects network attack vector, low attack complexity, privileges required at the contributor level, no user interaction, scope change, and partial confidentiality and integrity impact without availability impact. No public exploits have been reported yet, but the vulnerability is significant given the widespread use of WordPress and the AH Shortcodes plugin. The lack of available patches at the time of publication necessitates immediate attention from site administrators.

For European organizations, this vulnerability poses a risk to the confidentiality and integrity of web applications running WordPress with the AH Shortcodes plugin. Attackers with contributor-level access can inject persistent malicious scripts, potentially leading to session hijacking, unauthorized actions performed on behalf of users, defacement, or distribution of malware. This can erode user trust, damage brand reputation, and lead to regulatory compliance issues under GDPR if personal data is compromised. The vulnerability's exploitation could also facilitate lateral movement within an organization's web infrastructure or be used as a foothold for further attacks. Organizations with multi-user WordPress environments or those allowing external contributors are particularly vulnerable. The medium severity rating suggests a moderate but actionable risk, especially in sectors with high web presence such as e-commerce, media, and public services across Europe.

1. Immediately audit WordPress sites for the presence of the AH Shortcodes plugin and verify the version in use. 2. Apply any available patches or updates from the plugin vendor as soon as they are released. If no patch is available, consider disabling or removing the plugin temporarily. 3. Restrict Contributor-level access to trusted users only and review user roles to minimize unnecessary privileges. 4. Implement additional input validation and output encoding at the application or web server level to neutralize injected scripts. 5. Employ Web Application Firewalls (WAFs) with rules targeting known XSS patterns related to shortcode attributes. 6. Monitor logs and user activity for suspicious shortcode usage or unexpected content changes. 7. Educate content contributors about the risks of injecting untrusted content and enforce secure content creation policies. 8. Regularly back up website data to enable quick restoration in case of compromise. 9. Consider deploying Content Security Policy (CSP) headers to restrict script execution sources and mitigate impact of XSS.
