Improper Neutralization of Special Elements in Output Used by a Downstream Component ('Injection')

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

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.

How to fix Improper Neutralization of Special Elements in Output Used by a Downstream Component ('Injection')?

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

<3.71.0
