CVE-2025-11881 is a vulnerability identified in the AppPresser – Mobile App Framework plugin for WordPress, maintained by scottopolis. The flaw arises due to a missing authorization check (CWE-862) in the 'myappp_verify' function across all versions up to and including 4.5.0. This function fails to verify whether the requesting user has the necessary capabilities to access certain plugin data, allowing unauthenticated attackers to retrieve sensitive information such as the names and versions of installed plugins and themes. Such information disclosure can facilitate further targeted attacks by revealing potentially outdated or vulnerable components within the WordPress environment. The vulnerability is remotely exploitable without any authentication or user interaction, as indicated by the CVSS vector (AV:N/AC:L/PR:N/UI:N). The CVSS base score of 5.3 reflects a medium severity, primarily due to confidentiality impact without affecting integrity or availability. Although no public exploits have been reported, the exposure of detailed environment information increases the attack surface for adversaries conducting reconnaissance. The vulnerability is particularly relevant for organizations relying on WordPress sites integrated with the AppPresser framework, which is used to build mobile applications connected to WordPress backends. The lack of a patch link suggests that a fix may not yet be publicly available, emphasizing the need for interim mitigations. The vulnerability was published on October 30, 2025, with the data reserved earlier that month. Given the widespread use of WordPress and its plugins across various sectors, this vulnerability could be leveraged as a stepping stone in multi-stage attacks targeting European organizations.

For European organizations, the primary impact of CVE-2025-11881 is the unauthorized disclosure of sensitive configuration data, including plugin and theme names and version numbers. This information leakage can significantly aid attackers in identifying vulnerable components within the WordPress ecosystem, enabling more precise and effective attacks such as privilege escalation, remote code execution, or denial of service via known exploits targeting those components. While the vulnerability itself does not allow direct modification or disruption of data, the reconnaissance advantage it provides can lead to severe downstream consequences. Organizations in sectors with high reliance on WordPress for public-facing websites or mobile app backends—such as e-commerce, media, government, and financial services—may face increased risk of targeted attacks. Additionally, the exposure of version information can facilitate supply chain attacks or exploitation of zero-day vulnerabilities in related plugins or themes. The vulnerability's ease of exploitation without authentication or user interaction increases the likelihood of automated scanning and exploitation attempts, potentially affecting a broad range of organizations. European entities with stringent data protection regulations (e.g., GDPR) must consider the confidentiality breach implications and ensure appropriate incident response and risk mitigation measures are in place.

1. Monitor official channels from scottopolis and WordPress plugin repositories for the release of a security patch addressing CVE-2025-11881 and apply it promptly upon availability. 2. Until a patch is released, restrict access to the vulnerable 'myappp_verify' function endpoint by implementing web application firewall (WAF) rules that block or challenge unauthenticated requests targeting this function. 3. Employ IP whitelisting or authentication mechanisms at the web server or application level to limit access to plugin-related endpoints only to trusted users or internal networks. 4. Conduct regular audits of installed WordPress plugins and themes to identify outdated or vulnerable components and update them to the latest secure versions. 5. Implement comprehensive logging and monitoring to detect unusual access patterns or reconnaissance activities targeting WordPress plugins, enabling rapid incident response. 6. Educate development and operations teams about the risks of missing authorization checks and enforce secure coding practices for custom plugins or integrations. 7. Consider isolating WordPress instances hosting the AppPresser plugin in segmented network zones to reduce exposure. 8. Review and harden WordPress security configurations, including disabling unnecessary REST API endpoints or plugin features that expose sensitive data.
