Risk to organizations includes unauthorized access to sensitive resources, which can lead to further exploitation or data leakage. The vulnerability is currently classified as deferred, suggesting that it may not be actively exploited at this time. However, organizations should take this seriously and assess their exposure to potential threats.
Organizations should prioritize patching immediately due to the potential for exploitation if the vulnerable versions remain in use. Implementing strict access controls and regularly reviewing security configurations can help mitigate risks associated with this vulnerability.
The publication of this vulnerability on January 22, 2026, highlights the importance of staying updated with security patches and vulnerability disclosures. Security teams should ensure that they are monitoring updates specific to Mikado-Themes to remain vigilant against any future threats.
Vulnerability Details
The CVE-2026-22400 vulnerability is characterized by an authorization bypass through user-controlled keys in the Mikado-Themes Holmes application. This issue affects versions of Holmes from n/a through version 1.7. The vulnerability is categorized under CWE-639, indicating issues with incorrect access control implementations.
The CVSS score for this vulnerability is 5.4, indicating a medium severity level. This score reflects the attack vector as network-based, with low attack complexity and low privileges required for exploitation, making it accessible to a wider range of attackers. The confidentiality impact is none, while there is a low impact on integrity and availability.
Technical Analysis
The root cause of CVE-2026-22400 stems from the theme's failure to enforce appropriate access controls, allowing unauthorized users to gain access to resources they should not be able to access. The attack vector is via the network, where an attacker can exploit the vulnerability without any user interactions required.
The attack complexity is low, as attackers may only need to craft requests to bypass the access control checks. The privileges required for exploitation are also low, meaning that even users with limited access might exploit this vulnerability. The impacts on the confidentiality, integrity, and availability of the system are low to none, but the potential for unauthorized access remains a significant concern.
Risk & Impact Analysis
Real-world deployment risks include the possibility of attackers gaining unauthorized access to sensitive information or administrative functions within websites using Mikado-Themes Holmes. Organizations must realize that even medium-severity vulnerabilities can lead to severe consequences if left unaddressed.
The urgency for organizations to address this vulnerability is underscored by its potential for exploitation in the wild. While it has not been marked as actively exploited, the configuration issues allowing for this vulnerability are common in web applications, making it essential for security teams to review their access controls.
