https://notcve.org/view.php?id=CVE-2023-37259
18 Jul 2023 — matrix-react-sdk is a react-based SDK for inserting a Matrix chat/voip client into a web page. The Export Chat feature includes certain attacker-controlled elements in the generated document without sufficient escaping, leading to stored Cross site scripting (XSS). Since the Export Chat feature generates a separate document, an attacker can only inject code run from the `null` origin, restricting the impact. However, the attacker can still potentially use the XSS to leak message contents.

https://notcve.org/view.php?id=CVE-2023-30609
25 Apr 2023 — matrix-react-sdk is a react-based SDK for inserting a Matrix chat/VoIP client into a web page. Prior to version 3.71.0, plain text messages containing HTML tags are rendered as HTML in the search results. To exploit this, an attacker needs to trick a user into searching for a specific message containing an HTML injection payload. No cross-site scripting attack is possible due to the hardcoded content security policy. Version 3.71.0 of the SDK patches over the issue. • https://github.com/matrix-org/matrix-react-sdk/commit/bf182bc94556849d7acdfa0e5fdea2aa129ea826 • CWE-74: Improper Neutralization of Special Elements in Output Used by a Downstream Component ('Injection') •

17 May 2021 — Matrix-React-SDK is a react-based SDK for inserting a Matrix chat/voip client into a web page. Before version 3.21.0, when uploading a file, the local file preview can lead to execution of scripts embedded in the uploaded file. This can only occur after several user interactions to open the preview in a separate tab. This only impacts the local user while in the process of uploading. It cannot be exploited remotely or by other users. • https://github.com/matrix-org/matrix-react-sdk/pull/5981 • CWE-74: Improper Neutralization of Special Elements in Output Used by a Downstream Component ('Injection') CWE-434: Unrestricted Upload of File with Dangerous Type •
