    matrix-sdk-ui: Incomplete edit validation

    CVE-2026-45057 · GHSA-h97m-27fx-42rx

    Affected
    • crates.io matrix-sdk-ui < 0.16.1
    Fixed in
    0.16.1· Vendor fix available
    Issue
    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. [^1]: https://spec.matrix.org/unstable/client-server-api/#validity-of-replacement-events

    Recommended action: Upgrade to 0.16.1 or later, then redeploy and verify.A vendor fix does not resolve your finding until you verify it in your own systems.
