RUSTSEC-2026-0159 Sender-binding gaps in to-device messages

The matrix-sdk-crypto crate before 0.16.1 is missing a check for the sender's user ID when decrypting an Olm-encrypted to-device message containing the senderdevicekeys property. This could be exploited to spoof the sender of an encrypted to-device message, but only if the attacker colludes with ...
