    Summary: HTML injection in search results via plaintext message highlighting

    Details: ### Impact 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. Cross-site scripting is possible by including resources from `recaptcha.net` and `gstatic.com` which are included in the default CSP. Thanks to [Cadence Ember](https://cadence.moe/) for finding the injection and to [S1m](https://github.com/p1gp1g/) for finding possible XSS vectors. ### Patches Version 3.71.0 of the SDK fixes the issue. ### Workarounds Restarting the client will clear the injection.
