CVE-2024-52813: Matrix-Org Matrix-Rust-SDK

Medium severity, CVSS 4.3. EPSS: 0.5% chance of exploitation in the next 30 days.

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.

Affected products

• Matrix-Org Matrix-Rust-SDK: before 0.8.0 (fixed in 0.8.0)
