### Impact The message edit validation logic in the `matrix-sdk-ui` crate before 0.16.1 is missing a check: when replacing an encrypted event, the replacement event itself is not required to be encrypted. This enables a malicious homeserver administrator (or an actor with equivalent power) to impersonate or spoof messages as if they were sent by a victim user. ### Patches `matrix-sdk-ui` 0.16.1 fixes the message edit validation logic to align with the algorithm for replacement events[^1] described in the Matrix specification. ### Workarounds N/A ### References * Pull request: https://github.com/matrix-org/matrix-rust-sdk/pull/6454 ### For more information If you have any questions or comments about this advisory, please email us at [security at matrix.org](mailto:[email protected]).

AI coding agents often install or upgrade packages automatically in rust. A medium vulnerability in a dependency can be pulled into a project through a normal install or update without a human reviewing the change, expanding the blast radius from a single package to every agent workspace that depends on it.
