CVE-2025-11881 is a vulnerability classified under CWE-862 (Missing Authorization) affecting the AppPresser – Mobile App Framework plugin for WordPress, versions up to and including 4.5.0. The root cause is the absence of a capability check in the 'myappp_verify' function, which is responsible for verifying certain plugin operations. Due to this missing authorization control, unauthenticated attackers can invoke this function remotely without any credentials or user interaction, allowing them to extract sensitive metadata such as installed plugin and theme names and their version numbers. This information disclosure does not directly expose user data or allow modification of site content but provides attackers with reconnaissance data that can be leveraged to identify outdated or vulnerable components for subsequent targeted attacks. The vulnerability has a CVSS 3.1 base score of 5.3 (medium severity), reflecting its network attack vector, low complexity, no privileges required, and no user interaction needed. Although no public exploits are currently known, the flaw increases the attack surface by revealing internal configuration details that are typically protected. The lack of a patch link indicates that a fix may not yet be available, emphasizing the need for interim mitigations. This vulnerability primarily affects WordPress sites using the AppPresser plugin, which is popular for mobile app integration, thus potentially impacting a broad range of websites globally.

The primary impact of CVE-2025-11881 is unauthorized disclosure of sensitive site configuration information, specifically plugin and theme names and version numbers. This information can be exploited by attackers to identify outdated or vulnerable components, enabling more precise and effective follow-up attacks such as remote code execution, privilege escalation, or site defacement. While the vulnerability itself does not allow direct modification or data theft, it significantly lowers the barrier for attackers to conduct targeted exploitation campaigns. Organizations relying on the AppPresser plugin for mobile app functionality risk increased exposure to secondary attacks if they do not remediate this flaw. The impact is particularly critical for high-profile websites, e-commerce platforms, and enterprises where the compromise of web infrastructure can lead to reputational damage, financial loss, and regulatory penalties. Additionally, the vulnerability being exploitable without authentication and user interaction increases the likelihood of automated scanning and exploitation attempts by threat actors.

To mitigate CVE-2025-11881, organizations should first check for and apply any official patches or updates from the plugin vendor as soon as they become available. In the absence of a patch, administrators should consider disabling or removing the AppPresser plugin if it is not essential. Implementing web application firewall (WAF) rules to block or restrict access to the 'myappp_verify' endpoint can help prevent unauthorized requests. Restricting access to the WordPress admin and plugin endpoints by IP whitelisting or VPN-only access can reduce exposure. Regularly auditing installed plugins and themes for updates and known vulnerabilities will reduce the risk of chained exploits. Monitoring web server logs for unusual access patterns targeting the vulnerable function can provide early detection of exploitation attempts. Finally, educating development and security teams about the risks of missing authorization checks and enforcing secure coding practices will help prevent similar vulnerabilities in the future.
