CVE-2025-48150 is a medium-severity vulnerability classified under CWE-862 (Missing Authorization) affecting the WordPress plugin 'Real Estate Property 2024 Create Your Own Fields and Search Bar' developed by Bill Minozzi. This vulnerability arises from improper access control implementation within the plugin, allowing users with limited privileges (requiring at least some level of authentication) to perform actions or access functionality that should be restricted. Specifically, the issue is due to missing or incorrect authorization checks, which means that authenticated users with lower privileges can exploit the plugin to modify or interact with features they are not authorized to use. The vulnerability affects versions up to 4.48, though the exact range is not fully specified. The CVSS v3.1 base score is 4.3, indicating a medium impact primarily due to integrity loss without confidentiality or availability impact. The attack vector is network-based (remote exploitation possible), with low attack complexity, requiring privileges (PR:L) but no user interaction. The scope is unchanged, meaning the impact is limited to the vulnerable component itself. No known exploits are reported in the wild, and no patches have been linked yet. This vulnerability is significant because WordPress plugins are widely used and often targeted for privilege escalation and unauthorized data manipulation, especially in niche sectors like real estate where sensitive client and property data is managed.

For European organizations, particularly those operating real estate websites or platforms using WordPress with this plugin, the vulnerability poses a risk of unauthorized modification of property listings, custom fields, or search parameters. This could lead to data integrity issues such as incorrect property information being displayed, unauthorized changes to listings, or manipulation of search results, potentially damaging business reputation and client trust. While confidentiality and availability are not directly impacted, integrity compromises can have downstream effects on business operations and customer relations. Additionally, attackers with limited privileges could leverage this flaw as a foothold to escalate privileges or conduct further attacks within the WordPress environment. Given the widespread use of WordPress in Europe and the real estate sector's importance, this vulnerability could affect numerous small to medium enterprises that rely on this plugin for their online presence.

Organizations should immediately audit their WordPress installations to identify if the 'Real Estate Property 2024 Create Your Own Fields and Search Bar' plugin is installed and determine the version in use. Until an official patch is released, administrators should consider disabling or uninstalling the plugin to prevent exploitation. Implement strict role-based access controls within WordPress to limit plugin access only to trusted users. Monitor logs for unusual activities related to the plugin's functionalities, such as unexpected changes to custom fields or search configurations. Employ Web Application Firewalls (WAF) with rules targeting suspicious requests to the plugin endpoints. Regularly update WordPress core and all plugins once patches become available. Additionally, conduct penetration testing focused on authorization checks in custom plugins to proactively identify similar issues. For organizations with development capabilities, reviewing and hardening the plugin’s authorization logic or replacing it with more secure alternatives is advisable.
