CVE-2024-52813 – matrix-sdk-crypto missing facility to signal rotation of a verified cryptographic identity
https://notcve.org/view.php?id=CVE-2024-52813
07 Jan 2025 — matrix-rust-sdk is an implementation of a Matrix client-server library in Rust. Versions of the matrix-sdk-crypto Rust crate before 0.8.0 lack a dedicated mechanism to notify that a user's cryptographic identity has changed from a verified to an unverified one, which could cause client applications relying on the SDK to overlook such changes. matrix-sdk-crypto 0.8.0 adds a new VerificationLevel::VerificationViolation enum variant which indicates that a previously verified identity has been changed. • https://github.com/matrix-org/matrix-rust-sdk/pull/3795 • CWE-223: Omission of Security-relevant Information •

CVE-2024-40648 – `UserIdentity::is_verified` not checking verification status of own user identity while performing the check in matrix-rust-sdk
https://notcve.org/view.php?id=CVE-2024-40648
18 Jul 2024 — matrix-rust-sdk is an implementation of a Matrix client-server library in Rust. The `UserIdentity::is_verified()` method in the matrix-sdk-crypto crate before version 0.7.2 doesn't take into account the verification status of the user's own identity while performing the check and may as a result return a value contrary to what is implied by its name and documentation. If the method is used to decide whether to perform sensitive operations towards a user identity, a malicious homeserver could manipulate the ... • https://github.com/matrix-org/matrix-rust-sdk/commit/76a7052149bb8f722df12da915b3a06d19a6695a • CWE-287: Improper Authentication •
