An incompatibility between the format in which some Bitwarden clients upload attachments and sends could lead to those uploads being silently corrupted. We believe this is occurring only when using the mobile clients and only on the latest vaultwarden 1.25.1.
To mitigate this issue, we're releasing this quick patch to make any upload that could lead to a corrupted file explicitly return an error, notifying the user of the problem.
We recommend updating as soon as possible, and checking that any recently uploaded attachments can be downloaded and opened correctly (The corrupted uploads will return an error when downloading or download a very small file).
We've also fixed the docker volume check added in 1.25.1, if you previously needed to set I_REALLY_WANT_VOLATILE_STORAGE=true to start the container, please try again without it, and open an issue if it still won't start.
