CVE-2026-28104 is a missing authorization vulnerability affecting the Aryan Shirani Bid Abadi Site Suggest plugin. This vulnerability allows accessing functionality not properly constrained by ACLs, which can lead to unauthorized actions on the affected system. The vulnerability has been assigned a CVSS score of 6.5, categorizing it as medium severity. Organizations utilizing affected versions should be aware of the potential risks associated with this vulnerability.
The affected versions include all versions up to and including 1.3.9, making it critical for organizations using this plugin to evaluate their current deployments. The exploitation status remains deferred, indicating that while there are no confirmed exploits at this time, organizations should remain vigilant.
Risk to organizations includes unauthorized access to sensitive functionalities, potentially leading to data manipulation or exposure. Given the nature of the vulnerability, organizations should prioritize patching immediately to mitigate risks associated with unauthorized access.
Remediation involves updating the Site Suggest plugin to a version that addresses this vulnerability. Security teams should also consider implementing additional access controls and monitoring to detect any unauthorized attempts to exploit this vulnerability.
Vulnerability Details
The vulnerability is characterized by missing authorization, falling under the category of Broken Access Control (CWE-862). According to the CVSS 3.1 vector, the attack vector is network-based, with low complexity and no privileges required for exploitation. There is no user interaction required, and the potential impacts on confidentiality are negligible, while integrity and availability are moderately affected.
Technical Analysis
The root cause of this vulnerability stems from inadequate access controls, allowing unauthorized users to access functions that should be restricted. The attack vector being network-based means that an attacker can exploit this vulnerability remotely, without the need for physical access to the system.
The attack complexity is low, as there are no specific privileges required for exploitation, and there is no user interaction needed. The potential impacts include low integrity and availability, which can lead to operational disruptions and data integrity issues if exploited.
Risk & Impact Analysis
Real-world risk associated with CVE-2026-28104 includes unauthorized access to critical functionalities of the Site Suggest plugin. Exploitation of this vulnerability can lead to a broader attack surface, potentially affecting user data and operational integrity. The urgency for organizations to address this vulnerability is high, considering its medium CVSS score.
Organizations should assess the blast radius of this vulnerability to understand the potential impact on their operations. Given that it is not currently in the KEV catalog, immediate action should still be taken to patch the affected versions.
