CVE-2025-49910 is a missing authorization vulnerability identified in the WPGuppy WordPress plugin developed by AmentoTech Private Limited, affecting versions up to and including 1.1.4. The vulnerability arises because certain plugin functionalities are not properly constrained by Access Control Lists (ACLs), allowing unauthenticated remote attackers to invoke these functions without any privilege checks. This lack of authorization enforcement means attackers can access sensitive data or perform actions that should be restricted, compromising the confidentiality of the affected system. The vulnerability has a CVSS 3.1 base score of 8.2, reflecting its high severity, with an attack vector of network (AV:N), low attack complexity (AC:L), no privileges required (PR:N), no user interaction (UI:N), unchanged scope (S:U), high confidentiality impact (C:H), low integrity impact (I:L), and no availability impact (A:N). Although no public exploits are currently known, the ease of exploitation and the critical nature of the confidentiality breach make this a significant threat. The vulnerability affects installations of WPGuppy, a WordPress plugin used for form building and data collection, which is commonly deployed on websites to gather user input. The missing authorization could allow attackers to retrieve sensitive form data or manipulate plugin functions, potentially leading to data leakage or partial data tampering. Since WordPress is widely used across Europe, and WPGuppy is a popular plugin in certain sectors, the vulnerability poses a tangible risk to European organizations relying on this software for their web presence and data collection needs.

For European organizations, the primary impact of CVE-2025-49910 is the unauthorized disclosure of sensitive information collected or managed via the WPGuppy plugin, which can include personal data, business intelligence, or customer inputs. This breach of confidentiality could lead to regulatory non-compliance under GDPR, resulting in legal penalties and reputational damage. The partial integrity impact means attackers might also manipulate some data or plugin behavior, potentially undermining trust in the affected websites or services. Although availability is not impacted, the loss of confidentiality and integrity can disrupt business operations, especially for organizations relying heavily on web forms for customer interaction or internal workflows. The vulnerability's ease of exploitation without authentication or user interaction increases the risk of automated mass scanning and exploitation attempts, potentially targeting European organizations with high WordPress usage. This could lead to widespread data breaches or targeted attacks against critical sectors such as finance, healthcare, and e-commerce within Europe.

1. Monitor official channels from AmentoTech Private Limited and WordPress plugin repositories for the release of a security patch addressing CVE-2025-49910 and apply it immediately upon availability. 2. Until a patch is available, implement web application firewall (WAF) rules to restrict access to the vulnerable plugin endpoints, allowing only trusted IP addresses or authenticated users where feasible. 3. Conduct a thorough audit of the WPGuppy plugin usage on all WordPress sites to identify and isolate instances running vulnerable versions. 4. Employ custom access control mechanisms at the web server or application level to enforce authorization checks on plugin functionality, potentially by restricting HTTP methods or URL paths associated with the vulnerable features. 5. Regularly review and monitor web server logs for unusual access patterns targeting the plugin endpoints to detect and respond to exploitation attempts promptly. 6. Educate site administrators and developers about the risks of missing authorization vulnerabilities and encourage adherence to the principle of least privilege in plugin configurations and user roles. 7. Consider temporary deactivation of the WPGuppy plugin on critical systems if mitigation controls cannot be implemented swiftly, balancing operational impact against security risk.
