CVE-2026-32038·Docker vulnerability

OpenClaw before 2026.2.24 contains a sandbox network isolation bypass vulnerability that allows trusted operators to join another container's network namespace. Attackers can configure the docker.network parameter with container:<id> values to reach services in target container namespaces and bypass network hardening controls.

How to fix this CVE

Update Docker to version 2026.2.24 or later to close a critical sandbox escape vulnerability affecting network namespace isolation. This vulnerability allows operators with container access to bypass network segmentation by specifying arbitrary container network namespaces, potentially exposing inter-container traffic and services. Immediate patching is strongly recommended due to the CVSS 9.8 critical rating and unrestricted network access requirements.

How to check if you are affected

  1. Check installed Docker version: docker --version or docker version --format '{{.Server.Version}}'
  2. Verify if Docker daemon is running and accessible: docker ps to confirm you can query the container runtime
  3. Search Docker daemon logs for suspicious network.container parameter usage: grep -r 'docker.network.*container:' /var/lib/docker/ or check journalctl -u docker -n 500 for 'container:<id>' references in container creation events
  4. Confirm the fix: Re-run docker --version and verify the version is 2026.2.24 or later

FAQ

What is CVE-2026-32038?

CVE-2026-32038 is a critical sandbox isolation bypass in Docker's network namespace handling. An operator can abuse the docker.network parameter with container:<id> syntax to attach a container to another container's network namespace, circumventing network isolation controls and accessing restricted services.

Is CVE-2026-32038 being actively exploited?

No, CVE-2026-32038 is not currently listed in CISA's Known Exploited Vulnerabilities (KEV) catalog, and no public exploits are available. However, the low barrier to exploitation makes proactive patching essential.

What versions of Docker are affected by CVE-2026-32038?

All Docker versions prior to 2026.2.24 are vulnerable. The exact earliest affected version is unknown, but users should assume any version before 2026.2.24 requires patching.

How do I check if my server is vulnerable to CVE-2026-32038?

Run 'docker --version' and compare the version against 2026.2.24. If your version is lower, you are vulnerable. Additionally, audit your container orchestration for any docker.network=container:<id> usage patterns in recent deployments.

Does Defensia detect CVE-2026-32038?

Yes — Defensia's CVE advisory scanner compares installed package versions against the NVD database. If Docker is installed on a monitored server, CVE-2026-32038 will appear in your dashboard with remediation steps.

CVE-2026-40281CVSS 10Gotenberg is a Docker-powered stateless API for PDF files. In versions 8.30.1 and earlier, the metadata write endpoint validates metadata keys for control characters but leaves metadata values unsanitized. A newline character in a metadata value splits the ExifTool stdin line into two separate arguments, allowing injection of arbitrary ExifTool pseudo-tags such as -FileName, -Directory, -SymLink, and -HardLink. This is a bypass of the incomplete key-sanitization fix introduced in v8.30.1. An unauthenticated attacker can rename or move any PDF being processed to an arbitrary path in the container filesystem, overwrite arbitrary files, or create symlinks and hard links at arbitrary paths.
CVE-2026-57572CVSS 10Crawl4AI is an open-source LLM-friendly web crawler and scraper. Prior to 0.9.0, the Docker API server accepted request-supplied browser_config.extra_args, which flowed into Chromium's launch arguments. An attacker could inject Chromium switches that replace a child-process launch command together with --no-zygote, causing Chromium to fork or exec an attacker-controlled command as the container's runtime user. The Docker API is unauthenticated by default, so a single request yields arbitrary command execution. This issue is fixed in version 0.9.0.
CVE-2026-53576CVSS 10Kestra is an open-source, event-driven orchestration platform. Prior to 1.0.45 and 1.3.21, the authentication filter for the REST API (@Filter("/api/v1/**")) treats any request whose path ends in /configs as the public instance-config endpoint and forwards it without a credential check. kestra addresses its resources by URL path segments that the caller chooses (/api/v1/{tenant}/flows/{namespace}, /api/v1/{tenant}/executions/{namespace}/{id}, /api/v1/{tenant}/namespaces/{namespace}/kv/{key}). An anonymous caller picks the literal configs as the final segment, and the request bypasses Basic-Auth entirely. Because the bypass reaches the flow-create and execution-trigger routes, an unauthenticated caller creates a flow containing a Shell or Process task and runs it. The task executes as root inside the kestra container. The official docker-compose.yml mounts /var/run/docker.sock, so root in the container reaches the host Docker daemon. This vulnerability is fixed in 1.0.45 and 1.3.21.
CVE-2026-42298CVSS 10Postiz is an AI social media scheduling tool. Prior to commit da44801, a "Pwn Request" vulnerability in the Build and Publish PR Docker Image workflow (.github/workflows/pr-docker-build.yml) allows any unauthenticated user to execute arbitrary code during the Docker build process and exfiltrate a highly privileged GITHUB_TOKEN (write-all permissions). This can be achieved simply by opening a Pull Request from a fork with a maliciously modified Dockerfile.dev. This issue has been patched via commit da44801.
CVE-2026-26216CVSS 10Crawl4AI versions prior to 0.8.0 contain a remote code execution vulnerability in the Docker API deployment. The /crawl endpoint accepts a hooks parameter containing Python code that is executed using exec(). The __import__ builtin was included in the allowed builtins, allowing unauthenticated remote attackers to import arbitrary modules and execute system commands. Successful exploitation allows full server compromise, including arbitrary command execution, file read and write access, sensitive data exfiltration, and lateral movement within internal networks.
