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.","published":"2025-01-07T15:25:47.794Z","modified":"2026-08-12T03:51:29.216626037Z","cvss":{"score":4.3,"severity":"MEDIUM","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:N/A:N"},"epss":null,"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"crates.io","name":"matrix-sdk-crypto","fixedVersion":"0.8.0"}],"fix":{"url":"https://github.com/matrix-org/matrix-rust-sdk/pull/3795","label":"matrix-org/matrix-rust-sdk#3795"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2024/52xxx/CVE-2024-52813.json"},{"type":"ADVISORY","url":"https://github.com/matrix-org/matrix-rust-sdk/security/advisories/GHSA-r5vf-wf4h-82gg"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2024-52813"},{"type":"FIX","url":"https://github.com/matrix-org/matrix-rust-sdk/pull/3795"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-12T03:51:29.216626037Z"}}
