CVE-2026-25332 identifies a missing authorization vulnerability in the Endless Posts Navigation plugin developed by Fahad Mahmood, affecting all versions up to and including 2.2.9. The vulnerability arises from incorrectly configured access control mechanisms, allowing unauthorized users to perform actions that should be restricted. Specifically, the plugin fails to enforce proper authorization checks on certain functionalities, which could permit attackers to access or manipulate post navigation features without appropriate permissions. Although the exact technical exploitation details are not provided, missing authorization typically enables privilege escalation or unauthorized data exposure. The plugin is commonly used in WordPress environments to enhance post navigation capabilities, making affected websites vulnerable if the plugin is installed and active. No CVSS score has been assigned, and no known exploits have been observed in the wild as of the publication date. The vulnerability was reserved on February 2, 2026, and published on February 19, 2026. The lack of a patch link suggests that a fix may not yet be available, emphasizing the need for immediate mitigation steps. Given the nature of the vulnerability, attackers could exploit it remotely without authentication, increasing the risk profile for affected sites.

For European organizations, the impact of CVE-2026-25332 can be significant, especially for those relying on WordPress sites with the Endless Posts Navigation plugin installed. Unauthorized access could lead to data exposure, unauthorized content manipulation, or disruption of website navigation features, potentially harming the organization's reputation and user trust. In sectors such as e-commerce, media, or government services where website integrity and data confidentiality are critical, exploitation could result in regulatory non-compliance under GDPR due to unauthorized data access. Additionally, attackers might leverage this vulnerability as a foothold for further attacks within the network. The absence of authentication requirements for exploitation increases the risk of automated attacks and mass scanning. Although no known exploits exist yet, the vulnerability's presence in widely used CMS environments means the attack surface is broad, and opportunistic attackers may develop exploits rapidly.

European organizations should immediately audit their WordPress installations to identify the presence of the Endless Posts Navigation plugin, particularly versions up to 2.2.9. Until a patch is released, restrict access to the plugin’s functionalities by implementing web application firewall (WAF) rules that block unauthorized requests targeting the plugin endpoints. Employ strict role-based access controls within WordPress to limit plugin management and navigation features to trusted administrators only. Monitor web server and application logs for unusual or unauthorized access attempts related to the plugin. Consider temporarily disabling or uninstalling the plugin if it is not critical to operations. Keep abreast of vendor announcements for patches or updates and apply them promptly once available. Additionally, conduct regular security assessments and penetration tests focusing on plugin vulnerabilities. For organizations with high-security requirements, consider deploying runtime application self-protection (RASP) solutions to detect and block exploitation attempts in real-time.
