This required knowing an event ID to target. ### Patches Please upgrade to 1.0.1. ### Workarounds You can set the `matrixHandler.eventCacheSize` config value to `0` to workaround this bug. However, this may impact performance. ### Credits Discovered and reported by [Val Lorentz](https://valentin-lorentz.fr/). ### For more information If you have any questions or comments about this advisory email us at [[email protected]](mailto:[email protected]).
