How likely is exploitation

FIRST's Exploit Prediction Scoring System puts the probability of this CVE being exploited in the next 30 days at 0.18% — higher than 8% of all published CVEs. EPSS is an independent forecast of exploitation, not a severity rating: it says nothing about how much damage a successful attack does, which is what a CVSS score measures.

How to fix this CVE

Update Docker to version 3.0 or later to remediate this resource exhaustion vulnerability. The issue stems from Docker containers running without proper resource limits and security constraints, which can be exploited to trigger denial-of-service conditions. Ensure all Docker installations in your environment are patched and implement resource quotas at the container and host level to prevent future DoS attacks.

sudo dnf update docker-ce

How to check if you are affected

  1. Check your current Docker version by running: docker --version
  2. Verify if SINEC Traffic Analyzer (6GK8822-1BG01-0BA0) is deployed in your environment: docker ps --all | grep -i sinec
  3. Review container resource limits with: docker inspect <container_id> | grep -A 10 HostConfig
  4. Confirm the patch was applied by running: docker --version and verifying it reports 3.0 or higher

FAQ

What is CVE-2025-40766?

CVE-2025-40766 is a medium-severity vulnerability affecting Docker-based deployments of SINEC Traffic Analyzer where containers operate without adequate resource constraints or security isolation, potentially allowing attackers to exhaust system resources and cause service disruption.

Is CVE-2025-40766 being actively exploited?

No, this vulnerability is not currently listed on the CISA Known Exploited Vulnerabilities (KEV) catalog, and no public exploits are available at this time.

What versions of Docker are affected by CVE-2025-40766?

All versions of SINEC Traffic Analyzer (model 6GK8822-1BG01-0BA0) prior to version 3.0 are affected, which includes Docker installations used to run this application.

How do I check if my server is vulnerable to CVE-2025-40766?

Run 'docker --version' to verify your Docker version is 3.0 or higher, and check running containers with 'docker ps' to identify if SINEC Traffic Analyzer is deployed without memory and CPU limits.

Does Defensia detect CVE-2025-40766?

Yes — Defensia's CVE advisory scanner compares installed package versions against the NVD database. If Docker is installed on a monitored server, CVE-2025-40766 will appear in your dashboard with remediation steps.

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-2026-44182CVSS 10Jupyter Enterprise Gateway launches remote Jupyter Notebook kernels across distributed clusters like Apache Spark, Kubernetes, and Docker Swarm. In versions prior to 3.3.0, the server interpolates untrusted environment variables (e.g., KERNEL_XXX) into Kubernetes manifests without YAML-aware escaping, enabling YAML injection attacks. Attackers can inject new fields, overwrite critical fields (e.g., duplicate securityContext keys, where the last one prevails), and inject document boundaries (--- for new documents, ... for end-of-document) to generate multiple resources, potentially creating arbitrary types, such as privileged pods. The Jinja2 template for the Kubernetes manifest contains several kernel_xxx variables, such as kernel_working_dir that are used when rendering the manifest and are all vectors for YAML injection. This issue has been fixed in version 3.3.0.
CVE-2026-44181CVSS 10Jupyter Enterprise Gateway launches remote Jupyter Notebook kernels across distributed clusters like Apache Spark, Kubernetes, and Docker Swarm. In versions 2.0.0rc2 and above, prior to 3.3.0, the environment variables (KERNEL_XXX) used during the rendering of the Kubernetes manifest are vulnerable to Server Side Template Injection (SSTI). By including Jinja2 template expressions it is possible to execution Python code and OS Commands in the Enterprise Gateway service. The code can use or steal the Kubernetes service account token, which can steal Kubernetes secrets and be used to fully compromise the Kubernetes cluster by scheduling a privileged pod or a pod with a hostPath volume mount. This issue has been fixed in version 3.3.0.
CVE-2026-33587CVSS 10Lack of user input sanitisation in Open Notebook v1.8.3 allows the application user to execute Python code (and subsequently OS commands) on the docker container via Server-Side Template Injection (SSTI) for user-created transformations.
