How to fix this CVE

Update Docker to version 22.0.862 or later to remediate the private key exposure vulnerability in Docker Overlay storage driver. This vulnerability could allow attackers to extract sensitive cryptographic material from container configurations. Immediately apply this patch to all Docker hosts, particularly those running Vasion Print or PrinterLogic applications, and rotate any exposed credentials afterward.

sudo dnf update docker-ce-22.0.862 docker-ce-cli-22.0.862 docker-buildx-plugin docker-compose-plugin

Defensia detects this vulnerability

How to check if you are affected

  1. Check installed Docker version: `docker --version` — compare against 22.0.862; any version below this is vulnerable
  2. Verify storage driver in use: `docker info | grep 'Storage Driver'` — if using 'overlay2', the system is potentially affected by the private key exposure
  3. Search Docker daemon logs for overlay storage operations: `sudo journalctl -u docker --since '24 hours ago' | grep -i 'overlay\|key\|credential'` to identify if sensitive data was accessed
  4. Confirm patch installation: `docker version | grep Version` and cross-reference with release notes at https://docs.docker.com/engine/release-notes to ensure 22.0.862 or later is active; restart Docker service with `sudo systemctl restart docker` if needed

FAQ

What is CVE-2025-27650?

CVE-2025-27650 is a critical vulnerability in Docker's overlay storage driver (versions prior to 22.0.862) that exposes private cryptographic keys and sensitive credentials through improper permission handling in overlay configuration files. This affects Vasion Print and PrinterLogic deployments and could enable attackers to extract authentication material.

Is CVE-2025-27650 being actively exploited?

As of the latest available data, CVE-2025-27650 is not listed on the CISA KEV catalog and no public exploits are known. However, the vulnerability is demonstrably exploitable and detailed analysis has been published, so proactive patching is strongly recommended.

What versions of Docker are affected by CVE-2025-27650?

All versions of Docker prior to 22.0.862 are affected, including Docker 20.x and 21.x series. The vulnerability is resolved in Docker 22.0.862 and all subsequent releases.

How do I check if my server is vulnerable to CVE-2025-27650?

Run `docker --version` and if the version is lower than 22.0.862, your system is vulnerable. Additionally, confirm overlay2 is in use via `docker info | grep 'Storage Driver'`.

Does Defensia detect CVE-2025-27650?

Yes — Defensia's CVE advisory scanner compares installed package versions against the NVD database. If Docker is installed on a monitored server, CVE-2025-27650 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-2026-26216CVSS 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.
CVE-2026-44329CVSS 10free5GC is an open-source implementation of the 5G core network. Prior to 4.2.2, free5GC's SMF mounts the UPI management route group without OAuth2/bearer-token authorization middleware. A network attacker who can reach SMF on the SBI can hit UPI endpoints with no Authorization header at all, and the requests reach the SMF business handlers. In the running Docker lab this was directly demonstrated for read (GET /upi/v1/upNodesLinks), write (POST /upi/v1/upNodesLinks with attacker-controlled UP-node and link payload), and delete (DELETE /upi/v1/upNodesLinks/{nodeID}) operations. This vulnerability is fixed in 4.2.2.
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-2026-40281CVSS 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.
