Matrix JavaScript SDK's key history sharing could share keys to malicious devices ### Impact In matrix-js-sdk versions 9.11.0 through 34.7.0, the method `MatrixClient.sendSharedHistoryKeys` is vulnerable to interception by malicious homeservers. The method implements functionality proposed in [MSC3061](https://github.com/matrix-org/matrix-spec-proposals/pull/3061) and can be used by clients to share historical message keys with newly invited users, granting them access to past messages in the room. However, it unconditionally sends these "shared" keys to all of the invited user's devices, regardless of whether the user's cryptographic identity is verified or whether the user's devices are signed by that identity. This allows the attacker to potentially inject its own devices to receive sensitive historical keys without proper security checks. Note that this only affects clients running the SDK with the legacy crypto stack. Clients using the new Rust cryptography stack (i.e. those that call `MatrixClient.initRustCrypto()` instead of `MatrixClient.initCrypto()`) are unaffected by this vulnerability, because `MatrixClient.sendSharedHistoryKeys()` raises an exception in such environments. ### Patches Fixed in matrix-js-sdk 34.8.0 by removing the vulnerable functionality. ### Workarounds Remove use of affected functionality from clients. ### References - [MSC3061](https://github.com/matrix-org/matrix-spec-proposals/pull/3061) ### For more information If you have any questions or comments about this advisory, please email us at [security at matrix.org](mailto:security@matrix.org). |

Aliases: CVE-2024-50336 GHSA-xvg8-m4x3-w6xr |
The Matrix specification demands homeservers to perform validation of the server-name and media-id components of MXC URIs with the intent to prevent path traversal. However, it is not mentioned that a similar check must also be performed on the client to prevent client-side path traversal. matrix-js-sdk fails to perform this validation. |
