Details

Malicious homeservers can steal message keys when the matrix-react-sdk user invites another user to a room ### Impact matrix-react-sdk before 3.102.0 allows a malicious homeserver to potentially steal message keys for a room when a user invites another user to that room, via injection of a malicious device controlled by the homeserver. This is possible because matrix-react-sdk before 3.102.0 shared historical message keys on invite. ### Patches matrix-react-sdk 3.102.0 [disables sharing message keys on invite](https://github.com/matrix-org/matrix-react-sdk/pull/12618) by removing calls to the vulnerable functionality. ### Workarounds None. ### References The vulnerability in matrix-react-sdk is caused by calling `MatrixClient.sendSharedHistoryKeys` in matrix-js-sdk, which is inherently vulnerable to this sort of attack. This matrix-js-sdk vulnerability is tracked as CVE-2024-47080 / [GHSA-4jf8-g8wp-cx7c](https://github.com/matrix-org/matrix-js-sdk/security/advisories/GHSA-4jf8-g8wp-cx7c). Given that this functionality is not specific to sharing message keys on *invite*, is optional, has to be explicitly called by the caller and has been independently patched in matrix-react-sdk by removing the offending calls, we believe it is proper to treat the matrix-react-sdk vulnerability as a separate one, with its own advisory and CVE. The matrix-org/matrix-react-sdk repository has recently been archived and the project was moved to [element-hq/matrix-react-sdk](https://github.com/element-hq/matrix-react-sdk). Given that this happened *after* the first patched release, no releases of the project on [element-hq/matrix-react-sdk](https://github.com/element-hq/matrix-react-sdk) were ever vulnerable to this vulnerability. Patching pull request: https://github.com/matrix-org/matrix-react-sdk/pull/12618. ### For more information If you have any questions or comments about this advisory, please email us at security at [security at matrix.org](mailto:security@matrix.org).
