A Missing Authorization vulnerability exists in the FluentBoards plugin by Mahmudul Hasan Arif, which allows attackers to exploit incorrectly configured access control security levels. This vulnerability affects FluentBoards versions up to 1.91.1. The CVSS score is 5.4, indicating a medium severity level, which suggests that while the risk is not critical, it is significant enough to warrant prompt attention from security teams.
Risk to organizations includes unauthorized access and potential manipulation of data due to inadequate access controls. Given the nature of this vulnerability, attackers may leverage it to gain unauthorized privileges, which could lead to further exploitation within the affected systems. Organizations should prioritize addressing this vulnerability as part of their security posture.
Currently, there is no public exploit confirmed for this vulnerability, and it has not been included in the Known Exploited Vulnerabilities (KEV) catalog. However, organizations should remain vigilant and assess the impact of this vulnerability on their environments.
Organizations should address this vulnerability in their priority patch cycle to mitigate the associated risks effectively.
Vulnerability Details
The official description of CVE-2026-24561 states that it is a Missing Authorization vulnerability in the FluentBoards plugin, which allows for exploiting incorrectly configured access control security levels. This issue affects FluentBoards versions from n/a through 1.91.1. The vulnerability is classified under CWE-862, which pertains to lacking necessary authorization mechanisms.
The CVSS score is 5.4, indicating medium severity. The attack vector is network-based, with low attack complexity, requiring low privileges to exploit, and no user interaction necessary. The impact on confidentiality is none, while integrity and availability impacts are low.
Technical Analysis
The root cause of this vulnerability stems from improper access control configurations within the FluentBoards plugin. Attackers can exploit this misconfiguration to gain unauthorized access and potentially manipulate data without the need for user interaction.
The attack vector is network-based, and the complexity of the attack is low, meaning that attackers can easily exploit this vulnerability without sophisticated techniques. The privileges required for exploitation are low, allowing even users with limited permissions to execute attacks. The impacts on confidentiality are non-existent, while integrity and availability are minimally affected.
Risk & Impact Analysis
The deployment of this vulnerability poses a risk to organizations that utilize the FluentBoards plugin. Attackers may leverage the Missing Authorization vulnerability to gain unauthorized access, leading to data manipulation and potential breaches. The blast radius for this vulnerability can be significant, especially in environments where access controls are not strictly enforced.
Given the CVSS score of 5.4, organizations should prioritize patching this vulnerability in their security cycles to prevent exploitation and ensure their systems are secure.
