CVE-2025-14143 identifies a stored cross-site scripting vulnerability in the Ayo Shortcodes plugin for WordPress, specifically in all versions up to and including 0.2. The vulnerability stems from insufficient sanitization and escaping of the 'color' parameter within the ayo_action shortcode, which allows authenticated users with Contributor-level or higher privileges to inject arbitrary JavaScript code into WordPress pages. Because the malicious script is stored persistently, it executes whenever any user accesses the compromised page, potentially leading to session hijacking, defacement, or unauthorized actions performed in the context of the victim's browser session. The vulnerability requires authentication but no user interaction beyond viewing the infected page. The CVSS 3.1 score of 6.4 reflects a medium severity with network attack vector, low attack complexity, and privileges required at the contributor level. The scope is changed, as the vulnerability affects the confidentiality and integrity of data but not availability. No patches or fixes are currently linked, and no known exploits have been reported in the wild. The vulnerability is classified under CWE-79, which covers improper neutralization of input during web page generation, a common vector for XSS attacks. The plugin's widespread use in WordPress sites makes this a relevant threat for many organizations relying on this plugin for shortcode functionality.

The primary impact of this vulnerability is the potential compromise of user confidentiality and integrity on affected WordPress sites. Attackers with contributor-level access can inject malicious scripts that execute in the browsers of site visitors or administrators, potentially leading to session hijacking, theft of sensitive information such as cookies or credentials, unauthorized actions performed on behalf of users, and defacement of website content. Although availability is not directly impacted, the reputational damage and trust erosion from successful exploitation can be significant. Organizations relying on the Ayo Shortcodes plugin may face increased risk of targeted attacks, especially if their user base includes privileged users who can be compromised or coerced into injecting malicious content. The vulnerability's requirement for authenticated access limits exploitation to insiders or compromised accounts but does not eliminate risk, as contributor-level access is commonly granted in collaborative environments. The lack of known exploits in the wild suggests limited active exploitation currently, but the medium severity and ease of exploitation warrant proactive mitigation to prevent future attacks.

Organizations should immediately audit their WordPress installations to identify the presence of the Ayo Shortcodes plugin, especially versions up to 0.2. If an updated, patched version is released, promptly apply the update to remediate the vulnerability. In the absence of an official patch, consider disabling or removing the plugin to eliminate the attack surface. Restrict contributor-level access strictly to trusted users and review user permissions to minimize the number of accounts capable of exploiting this vulnerability. Implement Web Application Firewall (WAF) rules that detect and block suspicious input patterns targeting the 'color' parameter in the ayo_action shortcode. Conduct thorough input validation and output encoding on all user-supplied data within custom code or plugins to prevent similar issues. Monitor logs for unusual activity or script injection attempts and educate content contributors about the risks of injecting untrusted code. Regularly back up website data to enable recovery in case of compromise. Finally, consider deploying Content Security Policy (CSP) headers to limit the execution of unauthorized scripts on affected sites.
