CVE-2025-13822 is an authentication bypass vulnerability identified in MCPHub versions prior to 0.11.0. The vulnerability arises because certain endpoints lack adequate authentication middleware, allowing unauthenticated attackers to perform actions on behalf of legitimate users, effectively misusing their privileges. With a CVSS score of 5.3, categorized as medium severity, this vulnerability necessitates immediate attention from security teams.
The real-world implications of this vulnerability are significant, as it undermines the integrity of user accounts and can lead to unauthorized actions within the application. Organizations must recognize the urgency of addressing this flaw to protect sensitive data and maintain user trust.
As of now, there is no confirmed public exploit available for this vulnerability, but the potential for exploitation exists given its nature. Organizations using MCPHub should prioritize patching as soon as possible.
Organizations should prioritize patching immediately. The lack of exploitation data does not diminish the risk posed by this vulnerability, especially as attackers continuously seek to exploit such weaknesses.
Vulnerability Details
The official description states that MCPHub in versions below 0.11.0 is vulnerable to authentication bypass. This is classified under CWE-639, indicating insufficient authentication controls. The CVSS score of 5.3 reflects a medium severity level, where the attack vector is adjacent, and the attack complexity is low. The vulnerability can be exploited without any privileges or user interaction, which raises the stakes for organizations utilizing MCPHub.
The vulnerability was published on April 14, 2026, and has been classified as analyzed. Understanding the nature of this vulnerability is crucial for organizations relying on MCPHub for their operations.
Technical Analysis
The root cause of this vulnerability lies in the omission of adequate authentication middleware on certain endpoints within the MCPHub application. This oversight allows attackers to access functionalities intended for authenticated users without the necessary credentials.
The attack vector is classified as adjacent, implying that an attacker must be on the same network segment as the target. The complexity of this attack is low, meaning that a potential attacker can exploit this vulnerability with minimal effort. There are no privileges required, and no user interaction is necessary for the exploitation to occur.
The confidentiality and integrity impacts of this vulnerability are rated as low, meaning that while sensitive data may not be directly compromised, unauthorized actions can still have severe implications for system integrity and user trust.
Risk & Impact Analysis
The deployment of MCPHub in environments where sensitive operations occur poses a significant risk due to this vulnerability. Attackers leveraging this flaw could potentially manipulate user accounts without detection, leading to unauthorized transactions or data exposure.
With a CVSS score of 5.3, the urgency for remediation is marked as medium. Organizations must assess their exposure and take proactive measures to patch affected systems promptly.
The potential blast radius extends to all users of the MCPHub application, indicating that the ramifications of an attack could affect a wide array of users and systems. Therefore, addressing this vulnerability should be a priority for security teams.
