CVE-2026-110964 in Essential Real Estate Plugin
Summary
by MITRE • 11/04/2026
The Essential Real Estate WordPress plugin before 5.3.5 does not verify that a media attachment belongs to the requesting user before deleting it, allowing a self-registered customer-level user to delete other users' media library attachments, including those owned by administrators.

The vulnerability identified in The Essential Real Estate WordPress plugin prior to version 5.3.5 represents a critical failure in access control mechanisms within the application's media management functionality. This flaw specifically affects the process of deleting media attachments from the library. In secure software design, any operation that modifies or removes data associated with a specific user must strictly verify ownership and authorization before proceeding. However, this plugin fails to implement adequate checks to ensure that the user initiating the deletion request is indeed the owner of the targeted file. This oversight allows for unauthorized modification of resources belonging to other users within the system.
From a technical perspective, the core issue lies in the backend logic handling delete requests for media items. When a user submits a request to remove an attachment from the WordPress media library, the plugin does not cross-reference the current authenticated session's identity with the metadata stored for that specific file. Consequently, any authenticated user can construct or manipulate HTTP requests targeting arbitrary media IDs without restriction. This lack of server-side validation means that the application trusts client-supplied identifiers implicitly, assuming they are valid and authorized for the current context. Such a design pattern is fundamentally insecure as it bypasses essential integrity checks required to maintain data isolation between different user accounts.
The operational impact of this vulnerability is significant due to its potential for widespread disruption and data loss. A self-registered customer-level user, who typically possesses minimal privileges in most WordPress installations, can escalate their effective capabilities by exploiting this flaw. They are able to permanently delete media files belonging to administrators or other high-privilege users. This capability undermines the integrity of the website's content management system, potentially leading to broken links, loss of critical visual assets for real estate listings, and general instability in how property data is presented. Furthermore, because WordPress sites often rely on these images for SEO and user engagement, their removal can have tangible negative effects on business operations and online presence.
This vulnerability aligns with CWE-284, which describes Improper Access Control, specifically highlighting the failure to enforce proper restrictions on authorized individuals accessing a specific resource. It also maps directly to MITRE ATT&CK technique T1078, Valid Accounts, as it allows an attacker using legitimate but low-privileged credentials to perform actions outside their intended scope. The exploitation does not require complex injection techniques or remote code execution vectors; rather, it relies on simple manipulation of standard interface interactions that the application fails to secure properly.
To mitigate this risk, immediate action is required by updating The Essential Real Estate plugin to version 5.3.5 or later, where these access control checks have been implemented. Administrators should verify their installation versions and apply updates through the WordPress dashboard as soon as possible. In environments where patching cannot occur instantly due to compatibility concerns with other plugins or themes, temporary mitigations include restricting media library access via additional security plugins that enforce stricter user role permissions or implementing web application firewall rules that monitor for anomalous deletion patterns. Regular auditing of plugin code and adherence to secure coding standards that mandate explicit ownership verification before any destructive operation are essential practices to prevent similar vulnerabilities in the future.
