CVE-2025-11881 is a vulnerability classified under CWE-862 (Missing Authorization) found in the AppPresser – Mobile App Framework plugin for WordPress, developed by scottopolis. The flaw exists in the 'myappp_verify' function, which lacks proper capability checks, enabling unauthenticated attackers to retrieve sensitive data such as installed plugin and theme names and their version numbers. This information disclosure does not directly compromise system integrity or availability but provides valuable reconnaissance data that can facilitate subsequent targeted attacks, especially against outdated or vulnerable components identified through the leaked version information. The vulnerability affects all versions up to and including 4.5.0. Exploitation requires no privileges or user interaction and can be performed remotely over the network. The CVSS v3.1 base score is 5.3 (medium severity), reflecting the ease of exploitation and limited impact scope. No patches or known exploits are currently available, indicating a window of exposure for affected users. The vulnerability's presence in a widely used WordPress plugin framework increases its potential reach, particularly among organizations leveraging WordPress for mobile app integration. The lack of authorization checks represents a common security oversight that can be mitigated by implementing proper capability validation in the affected function.

For European organizations, the primary impact of CVE-2025-11881 is the unauthorized disclosure of sensitive configuration data, which can be leveraged by attackers to identify vulnerable plugin and theme versions for follow-on attacks. This reconnaissance can lead to more severe compromises if attackers exploit other known vulnerabilities in the disclosed components. Organizations relying on WordPress with the AppPresser plugin for mobile app integration may face increased risk of targeted attacks, potentially affecting customer data confidentiality and service reliability indirectly. While the vulnerability itself does not allow direct data modification or service disruption, it lowers the attacker's effort to breach defenses by providing critical intelligence. This can be particularly impactful for sectors with high regulatory requirements for data protection, such as finance, healthcare, and public services. Additionally, the exposure of plugin and theme versions may aid attackers in bypassing security controls or escalating privileges if combined with other vulnerabilities. The absence of patches and known exploits suggests a need for proactive risk management to prevent exploitation.

European organizations should immediately audit their WordPress environments to identify installations of the AppPresser – Mobile App Framework plugin, especially versions up to 4.5.0. Until an official patch is released, organizations should consider the following mitigations: 1) Restrict access to the vulnerable 'myappp_verify' endpoint by implementing web application firewall (WAF) rules that block unauthenticated requests targeting this function. 2) Employ network segmentation and access controls to limit exposure of WordPress administrative interfaces to trusted internal networks or VPN users only. 3) Monitor web server logs for suspicious requests attempting to access the vulnerable function and establish alerting for anomalous activity. 4) Disable or remove the AppPresser plugin if it is not essential to business operations to eliminate the attack surface. 5) Engage with the plugin vendor or community to track patch releases and apply updates promptly once available. 6) Conduct regular vulnerability scanning and penetration testing focused on WordPress environments to detect similar authorization issues. These targeted actions go beyond generic advice by focusing on immediate risk reduction through access control and monitoring.
