## Summary An authorization vulnerability was discovered in the `/rest/executions/:id/stop` endpoint of n8n. An authenticated user can stop workflow executions that they do not own or that have not been shared with them, leading to potential business disruption. ### Impact This is an **improper authorization** vulnerability. While most API methods enforce user-scoped access to workflow execution IDs, the `/stop` endpoint fails to do so. An attacker can guess or enumerate execution IDs (which are sequential and partially exposed via verbose error messages) and terminate active workflows initiated by other users. **Who is impacted:** - Environments where multiple users with varying trust levels share access to the same n8n instance. - All users running long-running or time-sensitive workflows (e.g., using the `wait` node). An attacker with authenticated access can exploit this flaw to: - Disrupt other users’ workflow executions. - Cause denial of service for business-critical automa...
This Fourth of July, Bruce, the 25-foot mechanical shark from Jaws, shares how his saltwater struggles mirror the need for real-world cybersecurity stress testing.
A vulnerability was identified in tarteaucitron.js where document.currentScript was accessed without verifying that it referenced an actual `<script>` element. If an attacker injected an HTML element such as: ``` <img name="currentScript" src="https://malicious.example.com"> ``` it could clobber the document.currentScript property. This causes the script to resolve incorrectly to an <img> element instead of the <script> tag, leading to unexpected behavior or failure to load the script path correctly. This issue arises because in some browser environments, named DOM elements (e.g., name="currentScript") become properties on the global document object. ## Impact An attacker with control over the HTML could exploit this to change the CDN domain of tarteaucitron. ## Fix https://github.com/AmauriC/tarteaucitron.js/commit/230a3b69d363837acfa895823d841e0608826ba3 The issue was resolved by verifying that document.currentScript is an instance of HTMLScriptElement. If not, the script now fa...
### Summary Path traversal is also known as directory traversal. These vulnerabilities enable an attacker to read arbitrary files on the server that is running an application. In this case, an attacker might be able to write to arbitrary files on the server, allowing them to modify application data or behavior, and ultimately take full control of the server. ### Details The file handler function trusts the filename provided by the user. This includes the cases when the user uses a path instead of the filename. This makes possible to write arbitrary files to the system and **replace** the files owned by _kuiper_ user on the filesystem. The vulnerable function is `fileUploadHandler` which is shown below: https://github.com/lf-edge/ekuiper/blob/1e6b6b6601445eb05316532f5fbef7f0a863ecfe/internal/server/rest.go#L329-L359 Exploitation of this vulnerability allows an attacker to rewrite the files owned by ekuiper including the main kuiper binaries as they are owned by _kuiper_ user: . All users should upgrade to this version or later. The fix introduces strict checking of URI patterns. Patch commit: https://github.com/n8n-io/n8n/pull/16229
