Security notice
Element Web 1.7.28 fixes (by upgrading to matrix-react-sdk 3.21.0) a low
severity issue (GHSA-8796-gc9j-63rv) related to file upload. When uploading a
file, the local file preview can lead to execution of scripts embedded in the
uploaded file, but only 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. Thanks to
Muhammad Zaid Ghifari for responsibly disclosing
this via Matrix's Security Disclosure Policy.
