Details

User content sandbox can be confused into opening arbitrary documents ### Impact The user content sandbox can be abused to trick users into opening unexpected documents after several user interactions. The content can be opened with a `blob` origin from the Matrix client, so it is possible for a malicious document to access user messages and secrets. ### Patches This has been fixed by https://github.com/matrix-org/matrix-react-sdk/pull/5657, which is included in 3.15.0. ### Workarounds There are no known workarounds.
