Outline is an open source, collaborative document editor. A type confusion issue was found in ProseMirror’s rendering process that leads to a Stored Cross-Site Scripting (XSS) vulnerability in Outline. An authenticated user can create a document containing a malicious JavaScript payload. When other users view this document, the malicious Javascript can execute in the origin of Outline. Outline includes CSP rules to prevent third-party code execution, however in the case of self-hosting and having your file storage on the same domain as Outline a malicious payload can be uploaded as a file attachment and bypass those CSP restrictions. This issue has been addressed in release version 0.77.3. Users are advised to upgrade. There are no known workarounds for this vulnerability.

InvenTree is an Open Source Inventory Management System. In affected versions of InvenTree it is possible for a registered user to store javascript in markdown notes fields, which are then displayed to other logged in users who visit the same page and executed. The vulnerability has been addressed as follows: 1. HTML sanitization has been enabled in the front-end markdown rendering library - `easymde`. 2. Stored markdown is also validated on the backend, to ensure that malicious markdown is not stored in the database. These changes are available in release versions 0.16.5 and later. All users are advised to upgrade. There are no workarounds, an update is required to get the new validation functions.
