CVE-2026-101065: Obot Docker Admin Access

How to Detect It

Start with asset discovery. Identify containers running Obot, published port 8080, Docker Compose files, systemd-managed Docker commands, and cloud security group rules that permit access to the service. Check whether the container includes /var/run/docker.sock and whether OBOT_SERVER_ENABLE_AUTHENTICATION is absent or set to a false value.

Review application logs for unauthenticated requests that perform administrative operations. The supplied records do not specify the exact Obot log schema or endpoint names, so defenders should avoid relying on one undocumented URI. Correlate source IP addresses, HTTP status codes, user identity fields, and administrative actions in the Obot logs with Docker events and reverse-proxy records.

Technical Notes

A generic reverse-proxy or web server query can identify requests associated with an unauthenticated administrative exposure when the application logs the synthetic identity:

user="nobody" AND (role="Owner" OR role="Admin")

If logs are JSON-formatted, an example SIEM query pattern is:

event.module:obot AND
(user.name:"nobody" OR user.id:"nobody") AND
(http.request.method:(POST OR PUT OR PATCH OR DELETE) OR
 url.path:(*admin* OR *mcp* OR *server*))

Adapt the exact field names to the deployed logging format. A useful network-side detection is any inbound connection from an untrusted source to TCP port 8080 on the Obot host, followed by HTTP requests that receive successful responses. For example, a firewall or flow query can begin with:

destination.port = 8080
AND source.ip NOT IN trusted_admin_ranges

On the Docker host, review container creation and execution activity around the time of suspicious Obot requests:

docker events --since 24h \
  --filter type=container \
  --filter event=create \
  --filter event=start

Also inspect current and recently stopped containers for unexpected images, commands, mounts, or network attachments. Docker event history may be incomplete after daemon restarts, so correlate it with daemon logs, container metadata, image-pull records, and reverse-proxy access logs.

Mitigation and Patching

The documented fix is configuration and documentation based. Operators who used the affected quickstart should enable authentication before exposing the service to any untrusted network:

OBOT_SERVER_ENABLE_AUTHENTICATION=true

For a Docker deployment, pass the setting explicitly and publish the service only where it is needed:

docker run \
  -e OBOT_SERVER_ENABLE_AUTHENTICATION=true \
  -p 127.0.0.1:8080:8080 \
  obot-platform/obot

The image name and other required deployment options may differ in a specific environment. The controls that matter here are enabling authentication and avoiding a broad host binding. If a reverse proxy is used, place it behind an identity-aware access control layer and restrict the backend so it cannot be reached directly.

A private VPN can help limit administrative access to the service, but it is not a replacement for application authentication or least-privilege configuration. Organizations evaluating a VPN should treat services such as NordVPN as one possible network-access control component, not as a fix for an exposed Docker socket or disabled Obot authentication.

There is no conventional fixed software version number in the supplied advisory. The affected scope ends at commit d7e6970, while the corrected quickstart enables authentication. Because the available records do not provide the exact remediation commit or a semantic release number, administrators should verify the current Obot repository and documentation before selecting an image tag. Do not claim compliance based only on pulling a newer image if authentication remains disabled.

Technical Notes

A Docker Compose-style workaround is:

services:
  obot:
    environment:
      OBOT_SERVER_ENABLE_AUTHENTICATION: "true"
    ports:
      - "127.0.0.1:8080:8080"

If the service must be remotely accessible, replace the loopback-only publication with a private management address or controlled reverse proxy. Apply firewall or security group rules that permit only trusted administrative networks. Do not expose the administrative interface directly to the public internet.

Inspect whether the Docker socket is mounted:

docker inspect <obot-container> \
  --format '{{json .Mounts}}' | jq

If it is not required for the deployment, remove the mount from the container definition and recreate the container. A temporary host-level check is:

docker inspect <obot-container> \
  --format '{{range .Mounts}}{{println .Source "->" .Destination}}{{end}}'

Look specifically for:

/var/run/docker.sock -> /var/run/docker.sock

Removing the socket may affect MCP runtime functionality, so test the application in a controlled environment. The safer long-term deployment model should isolate workloads and avoid granting an application direct access to the host Docker daemon where possible. The project documentation recommends Kubernetes for production or multi-tenant use, while the Docker socket-based configuration is intended for development, evaluation, or trusted single-tenant environments.

If the instance was reachable while unauthenticated, rotate Obot credentials, API tokens, MCP integration secrets, and any credentials accessible to launched workloads. Review registered MCP servers, recent configuration changes, Docker images, running containers, outbound connections, and host-level authentication logs. Preserve relevant logs before rebuilding or deleting containers.
