CVE-2024-8723 is a stored Cross-Site Scripting (XSS) vulnerability identified in the 012 Ps Multi Languages plugin for WordPress, which is widely used to provide multilingual support. The flaw exists in all versions up to and including 1.6, where the plugin fails to properly sanitize and escape input in translated titles. This improper neutralization of input (CWE-79) allows authenticated users with contributor-level permissions or higher to inject arbitrary JavaScript code into pages. When other users access these pages, the malicious scripts execute in their browsers, potentially leading to session hijacking, privilege escalation, or unauthorized actions within the WordPress environment. The vulnerability does not require user interaction beyond visiting the compromised page and can be exploited remotely over the network. The CVSS 3.1 score of 6.4 reflects a medium severity, considering the attack vector is network-based, the attack complexity is low, privileges are required, and the impact affects confidentiality and integrity but not availability. No public exploits have been reported yet, but the vulnerability is publicly disclosed and should be addressed promptly. The lack of patch links suggests that fixes may not yet be available or are pending release, emphasizing the need for interim mitigations.

The primary impact of this vulnerability is the potential compromise of user confidentiality and integrity within affected WordPress sites. Attackers with contributor-level access can inject malicious scripts that execute in the context of other users, including administrators, potentially leading to session hijacking, theft of sensitive information, unauthorized content modification, or further privilege escalation. This can result in defacement, data leakage, or the establishment of persistent backdoors. Since the vulnerability is stored XSS, the malicious payload persists on the site, increasing the risk of widespread impact. Organizations relying on the 012 Ps Multi Languages plugin expose themselves to reputational damage, loss of user trust, and potential regulatory consequences if sensitive data is compromised. The medium CVSS score reflects that while exploitation requires some privileges, the ease of attack and scope of impact warrant serious attention. The absence of known exploits in the wild currently limits immediate risk but does not preclude future exploitation.

Organizations should immediately audit their WordPress installations to identify the presence of the 012 Ps Multi Languages plugin and verify the version in use. Until an official patch is released, administrators should restrict contributor-level access to trusted users only and consider temporarily disabling or uninstalling the plugin if feasible. Implementing Web Application Firewall (WAF) rules to detect and block suspicious script injections in translated titles can provide interim protection. Additionally, site administrators should enforce strict Content Security Policy (CSP) headers to limit script execution sources and reduce the impact of injected scripts. Regularly monitoring logs for unusual activity and scanning for injected scripts can help detect exploitation attempts. Once a patch becomes available, prompt application is critical. Educating contributors about safe input practices and limiting the use of rich text or HTML in translations can further reduce risk. Backup procedures should be reviewed to ensure rapid recovery in case of compromise.
