Published: Tue Dec 16 2025 (12/16/2025, 08:12:53 UTC)
Source: CVE Database V5
Vendor/Project: g5theme
Product: Essential Real Estate

Description

CVE-2025-66127 is a medium severity vulnerability in the g5theme Essential Real Estate WordPress theme, affecting versions up to 5. 2. 2. It involves missing authorization controls, allowing users with limited privileges to perform actions beyond their intended access rights. The vulnerability does not require user interaction and can be exploited remotely over the network with low attack complexity, but requires some level of privileges (PR:L). The impact is limited to partial confidentiality and integrity loss without affecting availability. No known exploits are currently reported in the wild. European organizations using this theme, especially real estate businesses relying on WordPress, should prioritize patching or applying mitigations. Countries with significant WordPress usage and real estate market activity, such as Germany, France, and the UK, are more likely to be affected. Mitigation involves applying updates once available, reviewing user roles and permissions, and implementing additional access control monitoring.

Technical Analysis

CVE-2025-66127 is a missing authorization vulnerability found in the g5theme Essential Real Estate WordPress theme, affecting versions up to and including 5.2.2. This vulnerability arises from incorrectly configured access control security levels, which allow users with limited privileges (PR:L) to perform unauthorized actions that should be restricted. The vulnerability can be exploited remotely over the network (AV:N) without user interaction (UI:N), and the attack complexity is low (AC:L), meaning an attacker with some level of authenticated access can exploit it easily. The scope of the vulnerability is unchanged (S:U), indicating that the impact is confined to the vulnerable component without affecting other system components. The confidentiality and integrity of data can be partially compromised (C:L, I:L), but availability remains unaffected (A:N). The vulnerability does not currently have known exploits in the wild, but the lack of authorization checks could allow attackers to manipulate or access data they should not, potentially leading to data leakage or unauthorized content modification. Since the product is a WordPress theme tailored for real estate websites, the vulnerability could expose sensitive client or property data or allow unauthorized changes to listings and site content. The vulnerability was published on December 16, 2025, with a CVSS v3.1 base score of 5.4, categorized as medium severity. No patches or fixes are currently linked, so users must monitor vendor advisories for updates. The vulnerability was assigned by Patchstack, a known security entity specializing in WordPress ecosystem vulnerabilities.

Potential Impact

For European organizations, especially those operating real estate websites using the Essential Real Estate WordPress theme, this vulnerability poses a moderate risk. Unauthorized users with limited privileges could escalate their access to perform actions that compromise the confidentiality and integrity of sensitive data such as client information, property listings, and transaction details. This could lead to data leakage, reputational damage, and potential regulatory compliance issues under GDPR due to unauthorized data exposure. Although availability is not impacted, unauthorized content modification could disrupt business operations and customer trust. The threat is particularly relevant for small and medium real estate agencies that rely heavily on WordPress themes without extensive custom security controls. The absence of known exploits reduces immediate risk, but the ease of exploitation once an attacker gains limited access means organizations should act proactively. Additionally, attackers could leverage this vulnerability as a foothold for further attacks within the network, increasing overall risk.

Mitigation Recommendations

Organizations should immediately audit their WordPress installations to identify if the Essential Real Estate theme version 5.2.2 or earlier is in use. Until a patch is released, restrict user roles and permissions to the minimum necessary, especially limiting access to users who can modify theme settings or content. Implement web application firewalls (WAFs) with custom rules to detect and block suspicious requests targeting theme-specific endpoints. Monitor logs for unusual activity related to user privilege escalations or unauthorized content changes. Regularly back up website data and configurations to enable quick restoration if unauthorized modifications occur. Engage with the theme vendor or Patchstack for updates and apply patches promptly once available. Consider isolating the WordPress environment or deploying additional security plugins that enforce granular access control. Conduct security awareness training for administrators to recognize and respond to potential exploitation attempts. Finally, perform regular vulnerability scans and penetration tests focused on access control weaknesses in the WordPress environment.
