CVE-2025-63049 is a vulnerability identified in the ListingPro Lead Form plugin developed by CridioStudio, affecting versions up to 1.0.2. The core issue is a missing authorization check, meaning that certain functionalities within the lead form can be accessed without proper verification of user permissions. This flaw allows unauthenticated remote attackers to access data or functions that should be restricted by Access Control Lists (ACLs). The vulnerability is classified under the category of 'Missing Authorization,' which typically leads to unauthorized data exposure or functionality misuse. The CVSS 3.1 base score is 5.3, reflecting a medium severity level, with the vector indicating network attack vector (AV:N), low attack complexity (AC:L), no privileges required (PR:N), no user interaction (UI:N), unchanged scope (S:U), and limited confidentiality impact (C:L) but no impact on integrity (I:N) or availability (A:N). The vulnerability was published on December 9, 2025, with no known exploits in the wild at the time of reporting. The absence of patches at the time of disclosure suggests that organizations should prioritize monitoring and interim access control measures. The vulnerability could lead to unauthorized access to lead form submissions or related sensitive data, potentially exposing personal or business information collected via the plugin. Given the plugin’s use in WordPress environments, the attack surface includes websites that rely on ListingPro for lead generation, particularly in small and medium enterprises. The lack of authentication and user interaction requirements makes exploitation straightforward for remote attackers scanning for vulnerable endpoints.

For European organizations, the primary impact of CVE-2025-63049 is the potential unauthorized disclosure of lead form data, which may include personal identifiable information (PII) or business-sensitive information. This could lead to privacy violations under GDPR, resulting in regulatory penalties and reputational damage. The vulnerability does not affect system integrity or availability, so direct disruption or data manipulation is unlikely. However, unauthorized data access can facilitate further attacks such as phishing, social engineering, or targeted fraud. Organizations relying on ListingPro Lead Form for customer acquisition or communication may suffer loss of trust if data leakage occurs. The medium severity score indicates a moderate risk, but the ease of exploitation without authentication increases the urgency for mitigation. European businesses in sectors like real estate, professional services, and local commerce, which commonly use lead generation plugins, are particularly at risk. Additionally, the exposure of lead data could have downstream effects on partners and clients, amplifying the impact. The lack of known exploits in the wild currently reduces immediate risk, but proactive measures are essential to prevent future exploitation.

1. Monitor official CridioStudio channels and security advisories for the release of a patch addressing CVE-2025-63049 and apply it immediately upon availability. 2. Until a patch is available, implement web application firewall (WAF) rules to restrict access to the lead form endpoints, allowing only trusted IP addresses or authenticated users where feasible. 3. Conduct a thorough audit of access controls on the ListingPro Lead Form functionality to identify and close any unauthorized access paths. 4. Employ logging and monitoring solutions to detect unusual or unauthorized access attempts to the lead form, enabling rapid incident response. 5. Review and minimize the amount of sensitive data collected via the lead form to reduce exposure in case of unauthorized access. 6. Educate website administrators and developers about the importance of enforcing ACLs and regularly testing for authorization weaknesses. 7. Consider temporary disabling the lead form functionality if it is not critical to business operations until the vulnerability is remediated. 8. Perform penetration testing focused on authorization controls to uncover similar issues in other plugins or custom code.
