CVE-2025-49952 is an authorization bypass vulnerability identified in the favethemes Houzez WordPress theme, versions up to and including 4.1.1. The vulnerability stems from improperly configured access control mechanisms that rely on a user-controlled key, which attackers can manipulate to bypass authorization checks. This means that an attacker with limited privileges (PR:L) can escalate their access rights without needing user interaction (UI:N). The vulnerability is remotely exploitable over the network (AV:N) and affects confidentiality, integrity, and availability to a limited extent (C:L/I:L/A:L). The flaw allows unauthorized users to perform actions or access resources they should not be permitted to, potentially leading to data exposure or modification and disruption of service. Although no public exploits are currently known, the medium CVSS score of 6.3 indicates a significant risk if exploited. The issue affects the Houzez theme, widely used in real estate websites built on WordPress, which is a popular CMS worldwide. The root cause is a failure to properly validate or restrict user input that controls authorization keys, leading to incorrect access control enforcement. Since the vulnerability requires some level of privilege, attackers typically need to have an account on the affected site, but no further user interaction is necessary. The vulnerability was reserved in June 2025 and published in October 2025, with no patches or exploit code publicly available yet.

The impact of CVE-2025-49952 is primarily an unauthorized elevation of privileges within websites using the vulnerable Houzez theme. Attackers with low-level access can bypass authorization controls, potentially accessing sensitive user data, modifying content, or performing administrative actions depending on the site configuration. This can lead to data breaches, defacement, or disruption of services on real estate websites, damaging reputation and trust. Since Houzez is a commercial theme used globally, the scope includes numerous real estate agencies and property listing platforms. The vulnerability could facilitate further attacks such as data exfiltration, fraudulent listings, or unauthorized transactions. Although the impact on availability is limited, integrity and confidentiality risks are moderate. The requirement for some privileges limits exploitation to insiders or registered users, but the lack of user interaction and network exploitability increases risk. Organizations relying on this theme without timely mitigation face increased risk of compromise and potential regulatory consequences if personal data is exposed.

To mitigate CVE-2025-49952, organizations should immediately upgrade the Houzez theme to a patched version once available from the vendor. Until a patch is released, administrators should restrict user privileges to the minimum necessary, especially limiting the ability to control keys or parameters related to authorization. Implement input validation and sanitization on all user-controlled keys or parameters involved in access control decisions. Employ Web Application Firewalls (WAFs) to detect and block suspicious requests attempting to manipulate authorization keys. Monitor logs for unusual access patterns or privilege escalations. Conduct regular security audits of access control configurations within the theme and WordPress environment. Consider temporarily disabling features that rely on user-controlled keys for authorization if feasible. Educate site administrators and users about the risk and encourage strong password policies to reduce the risk of low-privilege account compromise. Finally, maintain up-to-date backups to recover quickly if an attack occurs.
