CVE-2026-24851·Docker vulnerability

OpenFGA is a high-performance and flexible authorization/permission engine built for developers and inspired by Google Zanzibar. OpenFGA v1.8.5 to v1.11.2 ( openfga-0.2.22<= Helm chart <= openfga-0.2.51, v.1.8.5 <= docker <= v.1.11.2) are vulnerable to improper policy enforcement when certain Check calls are executed. The vulnerability requires a model that has a a relation directly assignable by a type bound public access and assignable by type bound non-public access, a tuple assigned for the relation that is a type bound public access, a tuple assigned for the same object with the same relation that is not type bound public access, and a tuple assigned for a different object that has an object ID lexicographically larger with the same user and relation which is not type bound public access. This vulnerability is fixed in v1.11.3.

How to fix this CVE

Update Docker to version 1.11.3 or later to resolve an authorization bypass vulnerability in OpenFGA's policy enforcement logic. This vulnerability affects Docker installations running OpenFGA versions 1.8.5 through 1.11.2, where specific permission model configurations can lead to improper access control decisions. Immediately patch your Docker installation and validate that access control policies are functioning correctly after the update.

sudo dnf update docker-ce --setopt=install_weak_deps=False

Defensia detects this vulnerability

How to check if you are affected

  1. Step 1: Run `docker --version` and `docker version` to confirm installed Docker version; compare against 1.8.5–1.11.2 range to identify vulnerability
  2. Step 2: Check if OpenFGA is running within Docker by executing `docker ps --filter 'ancestor=openfga*' --format='table {{.Image}}\t{{.Status}}'`
  3. Step 3: Review Docker daemon logs for authorization failures: `sudo journalctl -u docker -n 1000 | grep -i 'permission\|authorization\|check'`
  4. Step 4: After patching, verify the new version with `docker --version` and restart the Docker daemon: `sudo systemctl restart docker`

FAQ

What is CVE-2026-24851?

CVE-2026-24851 is an authorization bypass vulnerability in Docker versions running OpenFGA 1.8.5 through 1.11.2. Under specific permission model conditions involving mixed public and non-public type-bound access tuples, the authorization engine may incorrectly grant access to resources that should be denied.

Is CVE-2026-24851 being actively exploited?

No, CVE-2026-24851 is not currently listed in CISA's Known Exploited Vulnerabilities (KEV) catalog and has no public exploit available. However, the high CVSS score (8.8) warrants immediate patching.

What versions of Docker are affected by CVE-2026-24851?

Docker versions 1.8.5 through 1.11.2 are vulnerable; Helm chart versions openfga-0.2.22 through openfga-0.2.51 are also affected. The fix is available in version 1.11.3 and later.

How do I check if my server is vulnerable to CVE-2026-24851?

Run `docker --version` and check if the version falls within 1.8.5–1.11.2. Additionally, inspect your authorization model configuration to confirm it matches the vulnerable pattern: a relation with both public type-bound and non-public type-bound assignments.

Does Defensia detect CVE-2026-24851?

Yes — Defensia's CVE advisory scanner compares installed package versions against the NVD database. If Docker is installed on a monitored server, CVE-2026-24851 will appear in your dashboard with remediation steps.

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-2026-57572CVSS 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-2026-40281CVSS 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-2026-26216CVSS 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.
