matrix-react-sdk@1.0.0-rc.1 vulnerabilities

matrix-react-sdk is a SDK for matrix.org using React

Affected versions of this package are vulnerable to Exposure of Private Personal Information to an Unauthorized Actor via a malicious homeserver, allowing an attacker to change the user's account data and cause the client to enable URL previews in end-to-end encrypted rooms. Exploiting this vulnerability causes any URLs in encrypted messages to be sent to the server.

Upgrade matrix-react-sdk to version 3.105.1 or higher.

Affected versions of this package are vulnerable to Improper Neutralization of Special Elements in Output Used by a Downstream Component ('Injection') such that 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.

Note: No cross-site scripting attack is possible due to the hardcoded content security policy.

Upgrade matrix-react-sdk to version 3.71.0 or higher.

Affected versions of this package are vulnerable to Prototype Pollution such that events sent with special strings in key places can temporarily disrupt or impede the matrix-react-sdk from functioning properly, causing room or event tile crashes. The remainder of the application can appear functional, though certain rooms/events will not be rendered.

Upgrade matrix-react-sdk to version 3.53.0 or higher.

Affected versions of this package are vulnerable to Cross-site Scripting (XSS). 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.

Upgrade matrix-react-sdk to version 3.21.0 or higher.

Affected versions of this package are vulnerable to Sandbox Bypass. The user content sandbox can be abused to trick users into opening unexpected documents. Messages and secrets are not at risk: the content is opened with a blob origin, which cannot access Matrix user data.

Upgrade matrix-react-sdk to version 3.15.0 or higher.
