CVE-2025-14999 identifies a Cross-Site Request Forgery (CSRF) vulnerability in the Latest Tabs WordPress plugin developed by kentothemes, affecting all versions up to 1.5. The vulnerability stems from missing or incorrect nonce validation on the settings update handler located in admin-page.php. Nonces in WordPress are security tokens used to verify that requests originate from legitimate users and not from malicious third parties. The absence or improper implementation of nonce checks allows an attacker to craft a malicious request that, when executed by an authenticated administrator (e.g., by clicking a specially crafted link), results in unauthorized modification of the plugin’s settings. Since the attack requires no authentication from the attacker but does require user interaction from an administrator, the attack vector is remote and user-initiated. The impact primarily affects the integrity of the plugin’s configuration, potentially enabling attackers to alter site behavior or weaken security controls embedded within the plugin’s settings. There is no direct impact on confidentiality or availability. The CVSS v3.1 base score is 4.3 (medium), reflecting the network attack vector, low attack complexity, no privileges required, but requiring user interaction and limited impact scope. No patches or exploits are currently documented, but the vulnerability is publicly disclosed and should be addressed promptly to prevent potential exploitation.

The primary impact of this vulnerability is the unauthorized modification of plugin settings by an attacker who tricks an administrator into executing a malicious request. This can lead to changes in website behavior, potentially introducing security weaknesses or disrupting functionality. Although the vulnerability does not directly expose sensitive data or cause denial of service, altered settings could be leveraged as a foothold for further attacks or to degrade site integrity. Organizations relying on the Latest Tabs plugin may face risks including compromised site configuration, reduced trustworthiness of the website, and increased administrative overhead to detect and remediate unauthorized changes. Since WordPress powers a significant portion of websites globally, and plugins are a common attack vector, this vulnerability could be exploited in targeted attacks against high-value sites or broadly in opportunistic campaigns if weaponized. The requirement for administrator interaction limits mass exploitation but does not eliminate risk, especially in environments with less security awareness or where phishing is prevalent.

To mitigate this vulnerability, organizations should first verify if they are using the Latest Tabs plugin version 1.5 or earlier and upgrade to a patched version once available. In the absence of an official patch, administrators can implement manual nonce validation in the plugin’s settings update handler to ensure requests are legitimate. Additionally, enforcing strict administrative access controls and limiting the number of users with plugin configuration privileges can reduce risk. Educating administrators about phishing and social engineering risks is critical to prevent inadvertent execution of malicious requests. Employing web application firewalls (WAFs) with rules to detect and block CSRF attempts targeting the plugin’s endpoints can provide an additional layer of defense. Regular monitoring of plugin settings for unauthorized changes and auditing administrative actions can help detect exploitation attempts early. Finally, maintaining up-to-date backups ensures recovery capability if unauthorized changes cause site disruption.
