CVE-2025-63049 identifies a missing authorization vulnerability in the ListingPro Lead Form plugin developed by CridioStudio, affecting all versions up to and including 1.0.2. The vulnerability arises because certain functionalities within the lead form are not properly constrained by Access Control Lists (ACLs), allowing unauthorized users to invoke these functions without proper permission checks. This can lead to unauthorized access or manipulation of lead form data, potentially exposing sensitive user information or enabling attackers to submit or alter lead data maliciously. The vulnerability does not require prior authentication, which increases the attack surface and ease of exploitation. Although no public exploits have been reported yet, the nature of the flaw suggests that attackers could automate exploitation attempts to access or manipulate data. The ListingPro Lead Form is typically used in WordPress environments to capture leads and customer information, making it a critical component for businesses relying on web-based customer acquisition. The lack of a CVSS score means severity assessment must consider the impact on confidentiality and integrity, ease of exploitation, and scope. Since the vulnerability allows unauthorized access without user interaction or authentication, it represents a significant risk to affected organizations. The absence of patches at the time of publication necessitates immediate attention to alternative mitigations and monitoring.

For European organizations, this vulnerability poses a risk of unauthorized access to lead data collected via the ListingPro Lead Form plugin. This could result in exposure of personal data, violating GDPR and other data protection regulations, leading to legal and reputational consequences. Attackers could manipulate lead submissions, corrupting data integrity and potentially disrupting business processes reliant on accurate lead information. Organizations using this plugin on public-facing websites are particularly vulnerable, as the flaw does not require authentication, allowing remote exploitation. The impact extends to customer trust and compliance posture, especially for companies in sectors like marketing, real estate, and services that heavily depend on lead generation. Additionally, the vulnerability could be leveraged as a foothold for further attacks within the web infrastructure if combined with other weaknesses. The lack of known exploits currently reduces immediate risk but does not diminish the potential impact if exploited. European entities must consider the regulatory implications of data breaches resulting from this vulnerability.

1. Monitor official CridioStudio channels and security advisories for patches addressing CVE-2025-63049 and apply them promptly once available. 2. Until a patch is released, restrict access to the lead form functionality by implementing web application firewall (WAF) rules that limit requests to trusted IP ranges or require additional authentication layers. 3. Conduct a thorough audit of the lead form usage and access logs to detect any unauthorized or suspicious activity. 4. Implement strict role-based access controls (RBAC) at the WordPress level to minimize exposure of the lead form endpoints. 5. Consider temporarily disabling the ListingPro Lead Form plugin if it is not critical to business operations or if alternative lead capture methods exist. 6. Employ security plugins that can enforce additional authorization checks or rate limiting on form submissions. 7. Educate web administrators and developers about the risks of missing authorization and encourage secure coding practices for customizations. 8. Regularly back up lead data and website configurations to enable recovery in case of compromise. 9. Review and enhance overall WordPress security posture, including timely updates and minimal plugin usage.
