## Impact 1. A compromised instance with shared folders could sync malicious files which contain arbitrary HTML and JavaScript in the name. If the owner of another device looks over the shared folder settings and moves the mouse over the latest sync, a script could be executed to change settings for shared folders or add devices automatically. 2. Adding a new device with a malicious name could embed HTML or JavaScript inside parts of the page. ## Risk As long as trusted devices are used, the risk is low. Additionally, the web GUI is not used that often in daily use which reduces the likelihood of exploitation. ## Details ### 1. Field "Latest Change" * Open the web GUI at [http://127.0.0.1:8384/](http://127.0.0.1:8384/). * Create/Delete a file named ```<img src=a onerror=alert(123)>``` and sync it to the other instance. * Move your mouse over the latest change to trigger the tooltip. <img width="834" alt="latest-change" src="https://user-images.githubusercontent.com/9484134/2050...

### Summary Some avo fields are vulnerable to XSS when rendering html based content. ### Details During the analysis of the web application, a rendered field was discovered that did not filter JS / HTML tags in a safe way and can be abused to execute js code on a client side. The trix field uses the trix editor in the backend to edit rich text data which basically operates with html tags. To display the stored data in a rendered view, the HasHTMLAttributes concern is used. This can be exploited by an attacker to store javascript code in any trix field by intercepting the request and modifying the post data, as the trix editor does not allow adding custom html or js tags on the frontend. ### PoC  _Adding javascript in the post request which is used when editing a "post" resource (body is declared as a trix field)_  base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section.This content is licensed under the Creative Commons Attribution 4.0 International License (https://creativecommons.org/licenses/by/4.0/).
