Fudo Enterprise in versions from 5.5.0 through 5.6.2 allows low privileged users to access certain administrator-only resources via improperly protected API endpoints. This includes sensitive information such as system logs and parts of system configuration settings. This vulnerability has been fixed in version 5.6.3. The CVSS score for this vulnerability is 5.1, indicating a medium severity.
Risk to organizations includes unauthorized access to sensitive information, which can lead to data breaches or system misconfigurations. The vulnerability is classified as having an attack vector of adjacent network, with low complexity and requires low privileges to exploit. Organizations should prioritize patching immediately to mitigate the risk.
Currently, there is no public exploit confirmed for this vulnerability, and it is not listed in the Known Exploited Vulnerabilities (KEV) catalog. However, as it affects API endpoints, organizations should remain vigilant and ensure that their API configurations are secured against unauthorized access.
Organizations should address this vulnerability in their priority patch cycle to prevent potential data exposure.
Vulnerability Details
The vulnerability allows low privileged users to gain access to sensitive administrator-only resources through improperly protected API endpoints. This vulnerability is classified under CWE-863, which pertains to improper authorization.
The CVSS score of 5.1 signifies medium severity, with an attack vector of adjacent network, low attack complexity, and low privileges required. The vulnerability's confidentiality impact is rated as high.
The affected product is Fudo Enterprise, with specific versions ranging from 5.5.0 to 5.6.2. The vulnerability was published on April 20, 2026, and has since been addressed in version 5.6.3.
Technical Analysis
The root cause of this vulnerability lies in the improper protection of API endpoints, allowing low privileged users to access sensitive information. The attack vector is adjacent, which implies potential local network access. With low attack complexity, attackers can exploit this vulnerability with minimal effort.
The requirement for privileges is low, meaning that even users with basic access may exploit this vulnerability without significant barriers. User interaction is not necessary, which further simplifies the exploitation process, increasing the risk to organizations.
In terms of impact, the confidentiality of the information accessed can be high, as it can include system logs and configuration settings. However, there is no integrity or availability impact associated with this vulnerability.
Risk & Impact Analysis
The real-world deployment risk associated with this vulnerability is substantial, especially for organizations using Fudo Enterprise in sensitive environments. Attackers may leverage this flaw to gain unauthorized access to sensitive information, which could lead to data breaches or compliance violations.
Given the high confidentiality impact, organizations relying on Fudo Enterprise should treat this vulnerability as a significant threat. The urgency for remediation is medium, as organizations should schedule patching in their priority patch cycle to mitigate risks.
The blast radius potential is notable due to the accessibility of sensitive information, which could affect multiple parts of the organization if exploited. Organizations should maintain vigilance and review their API security practices to prevent unauthorized access.
