CVSS: 6.1EPSS: 0%CPEs: 3EXPL: 0CVE-2023-37259 – Cross site scripting in Export Chat feature
https://notcve.org/view.php?id=CVE-2023-37259
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. A malicious homeserver is a potential attacker since the affected inputs are controllable server-side. • https://github.com/matrix-org/matrix-react-sdk/commit/22fcd34c606f32129ebc967fc21f24fb708a98b8 https://github.com/matrix-org/matrix-react-sdk/security/advisories/GHSA-c9vx-2g7w-rp65 • CWE-79: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') •
CVSS: 5.4EPSS: 0%CPEs: 1EXPL: 0CVE-2023-30609 – matrix-react-sdk vulnerable to HTML injection in search results via plaintext message highlighting
https://notcve.org/view.php?id=CVE-2023-30609
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 https://github.com/matrix-org/matrix-react-sdk/releases/tag/v3.71.0 https://github.com/matrix-org/matrix-react-sdk/security/advisories/GHSA-xv83-x443-7rmw • CWE-74: Improper Neutralization of Special Elements in Output Used by a Downstream Component ('Injection') •
CVSS: 8.2EPSS: 0%CPEs: 1EXPL: 0CVE-2023-28103 – Prototype pollution in matrix-react-sdk
https://notcve.org/view.php?id=CVE-2023-28103
matrix-react-sdk is a Matrix chat protocol SDK for React Javascript. In certain configurations, data sent by remote servers containing special strings in key locations could cause modifications of the `Object.prototype`, disrupting matrix-react-sdk functionality, causing denial of service and potentially affecting program logic. This is fixed in matrix-react-sdk 3.69.0 and users are advised to upgrade. There are no known workarounds for this vulnerability. Note this advisory is distinct from GHSA-2x9c-qwgf-94xr which refers to a similar issue. • https://github.com/matrix-org/matrix-react-sdk/security/advisories/GHSA-6g43-88cp-w5gv https://matrix.org/blog/2023/03/28/security-releases-matrix-js-sdk-24-0-0-and-matrix-react-sdk-3-69-0 • CWE-1321: Improperly Controlled Modification of Object Prototype Attributes ('Prototype Pollution') •
CVSS: 7.8EPSS: 0%CPEs: 1EXPL: 0CVE-2021-32622 – File upload local preview can run embedded scripts after user interaction
https://notcve.org/view.php?id=CVE-2021-32622
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 https://github.com/matrix-org/matrix-react-sdk/security/advisories/GHSA-8796-gc9j-63rv • CWE-74: Improper Neutralization of Special Elements in Output Used by a Downstream Component ('Injection') CWE-434: Unrestricted Upload of File with Dangerous Type •
CVSS: 4.3EPSS: 0%CPEs: 1EXPL: 0CVE-2021-21320 – User content sandbox can be confused into opening arbitrary documents
https://notcve.org/view.php?id=CVE-2021-21320
matrix-react-sdk is an npm package which is a Matrix SDK for React Javascript. In matrix-react-sdk before version 3.15.0, the user content sandbox can be abused to trick users into opening unexpected documents. The content is opened with a `blob` origin that cannot access Matrix user data, so messages and secrets are not at risk. This has been fixed in version 3.15.0. matrix-react-sdk es un paquete npm que es un Matrix SDK para React Javascript. En matrix-react-sdk anterior a la versión 3.15.0, el sandbox del contenido del usuario puede ser abusado para engañar a los usuarios para que abran documentos inesperados. • https://github.com/matrix-org/matrix-react-sdk/commit/b386f0c73b95ecbb6ea7f8f79c6ff5171a8dedd1 https://github.com/matrix-org/matrix-react-sdk/pull/5657 https://github.com/matrix-org/matrix-react-sdk/security/advisories/GHSA-52mq-6jcv-j79x https://www.npmjs.com/package/matrix-react-sdk • CWE-345: Insufficient Verification of Data Authenticity •
