CVE-2025-13822 MCPHub CVE debrief

AI-assisted PatchSiren debrief based on the supplied source corpus. The CVE record was published on 2026-04-14T11:16:24.300Z and has not been modified since then. MCPHub versions below 0.11.0 are vulnerable to authentication bypass due to some endpoints lacking authentication middleware. This allows unauthenticated attackers to perform actions as other users, potentially leading to unauthorized access and privilege escalation. Administrators and users of MCPHub, especially those with versions below 0.11.0, should be aware of this vulnerability and take necessary defensive actions to prevent potential authentication bypass attacks.

Who should care

Administrators and users of MCPHub, especially those with versions below 0.11.0, should be aware of this vulnerability and take necessary defensive actions to prevent potential authentication bypass attacks. This includes reviewing and updating authentication configurations for MCPHub endpoints and implementing compensating controls such as IP restrictions or monitoring for suspicious activity.

Technical summary

MCPHub versions below 0.11.0 are vulnerable to authentication bypass due to some endpoints lacking authentication middleware. This allows unauthenticated attackers to perform actions as other users, potentially leading to unauthorized access and privilege escalation. The vulnerability affects MCPHub deployments, and defenders should verify their environments for affected versions.

Defensive priority

Medium-priority defensive actions are recommended due to the potential for authentication bypass in MCPHub versions below 0.11.0.

Recommended defensive actions

  • Inventory MCPHub installations and verify versions are up-to-date or 0.11.0 or later
  • Implement compensating controls such as IP restrictions or monitoring for suspicious activity
  • Review and update authentication configurations for MCPHub endpoints
  • Consider applying network segmentation to limit potential attack paths
  • Monitor for and respond to potential authentication bypass attempts

Evidence notes

Evidence from the NVD and CVE Program indicates that MCPHub versions below 0.11.0 are vulnerable to authentication bypass. Some endpoints lack authentication middleware, allowing unauthenticated attackers to perform actions as other users. The CVE Program and NVD provide official records and assessments of this vulnerability. Additional information from third-party advisories, such as those from cert.pl, may also be relevant.
