CVE-2024-52813— matrix-sdk-crypto missing facility to signal rotation of a verified cryptographic identity
Quick assessment
Affected
matrix-org matrix-rust-sdk
Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.
matrix-rust-sdk是Matrix开源的一个 Rust 中 Matrix 客户端-服务器库的实现。 matrix-rust-sdk 0.8.0之前版本存在安全漏洞，该漏洞源于缺少专用机制通知用户的加密身份从已验证变为未验证，可导致依赖该SDK的客户端应用忽略此类变化。

Vulnerability Title
matrix-sdk-crypto missing facility to signal rotation of a verified cryptographic identity
Source: CVE Program / CVE List V5
Vulnerability Description
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.
