{"id":"CVE-2024-40648","summary":"`UserIdentity::is_verified` not checking verification status of own user identity while performing the check in matrix-rust-sdk","details":"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 outcome in order to make the identity appear trusted. This is not a typical usage of the method, which lowers the impact. The method itself is not used inside the `matrix-sdk-crypto` crate. The 0.7.2 release of the `matrix-sdk-crypto` crate includes a fix. All users are advised to upgrade. There are no known workarounds for this vulnerability.","aliases":["GHSA-4qg4-cvh2-crgg","RUSTSEC-2024-0356"],"modified":"2026-11-04T02:46:18.384429853Z","published":"2024-07-18T16:45:56.321Z","related":["openSUSE-SU-2024:14224-1"],"database_specific":{"cwe_ids":["CWE-287"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2024/40xxx/CVE-2024-40648.json","cna_assigner":"GitHub_M"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2024/40xxx/CVE-2024-40648.json"},{"type":"ADVISORY","url":"https://github.com/matrix-org/matrix-rust-sdk/security/advisories/GHSA-4qg4-cvh2-crgg"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2024-40648"},{"type":"FIX","url":"https://github.com/matrix-org/matrix-rust-sdk/commit/76a7052149bb8f722df12da915b3a06d19a6695a"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/matrix-org/matrix-rust-sdk","events":[{"introduced":"0"},{"fixed":"d2d286bf291426eb4e39c52e80bec1163791e338"},{"fixed":"76a7052149bb8f722df12da915b3a06d19a6695a"}],"database_specific":{"extracted_events":[{"source":"AFFECTED_FIELD","strategy":"StringRangeExpression","range":[{"introduced":"0"},{"fixed":"0.7.2"}]},{"range":[{"fixed":"76a7052149bb8f722df12da915b3a06d19a6695a"}],"source":"REFERENCES_COMMIT"}]}}],"versions":["matrix-sdk-ffi/20240704","matrix-sdk-ffi/20240618","matrix-sdk-crypto-ffi-0.4.2","matrix-sdk-crypto-ffi-0.4.1","matrix-sdk-crypto-ffi-0.4.0","0.7.0","matrix-sdk-crypto-ffi-0.3.13","matrix-sdk-crypto-ffi-0.3.12","matrix-sdk-crypto-ffi-0.3.11","matrix-sdk-crypto-ffi-0.3.10","matrix-sdk-crypto-ffi-0.3.9","matrix-sdk-crypto-ffi-0.3.8","matrix-sdk-crypto-ffi-0.3.7","matrix-sdk-crypto-ffi-0.3.5","matrix-sdk-crypto-ffi-0.3.4","matrix-sdk-crypto-ffi-0.3.2","matrix-sdk-crypto-ffi-0.3.1","matrix-sdk-crypto-ffi-0.3.0","matrix-sdk-crypto-ffi-0.2.1","matrix-sdk-crypto-js-v0.1.0-alpha.4","matrix-sdk-crypto-ffi-0.2.0","matrix-sdk-crypto-ffi-0.1.10","matrix-sdk-crypto-ffi-0.1.9","matrix-sdk-crypto-ffi-0.1.8","matrix-sdk-crypto-ffi-0.1.7","matrix-sdk-crypto-js-v0.1.0-alpha.2","matrix-sdk-crypto-js-v0.1.0-alpha.1","matrix-sdk-crypto-js-v0.1.0-alpha.0","matrix-sdk-crypto-ffi-0.1.6","matrix-sdk-crypto-ffi-0.1.5","matrix-sdk-crypto-ffi-0.1.4","matrix-sdk-crypto-ffi-0.1.3","matrix-sdk-crypto-ffi-0.1.2","matrix-sdk-crypto-ffi-0.1.1","matrix-sdk-crypto-ffi-0.1.0","matrix-sdk-crypto-0.4.1","matrix-sdk-common-0.4.1","matrix-sdk-base-0.4.1","matrix-sdk-0.4.1","matrix-sdk-0.4.0","matrix-sdk-crypto-0.4.0","matrix-sdk-base-0.4.0","matrix-qrcode-0.2.0","matrix-sdk-test-0.4.0","matrix-sdk-common-0.4.0","ruma-client-api-0.10.2","ruma-common-0.5.2","ruma-0.1.1","ruma-events-0.22.2","ruma-client-api-0.10.1","ruma-events-0.22.1","ruma-0.1.0","ruma-state-res-0.1.0","ruma-client-0.5.0","ruma-push-gateway-api-0.1.0","ruma-identity-service-api-0.1.0","ruma-appservice-api-0.2.0","ruma-federation-api-0.1.0","ruma-client-api-0.10.0","ruma-api-0.17.0","ruma-events-0.22.0","ruma-common-0.5.1","ruma-signatures-0.7.1","ruma-identifiers-0.19.1","ruma-serde-0.4.0","ruma-client-0.5.0-alpha.2","ruma-0.0.3","ruma-push-gateway-api-0.1.0-alpha.1","ruma-identity-service-api-0.1.0-alpha.1","ruma-federation-api-0.1.0-alpha.2","ruma-client-api-0.10.0-alpha.3","ruma-appservice-api-0.2.0-alpha.3","ruma-api-0.17.0-alpha.4","ruma-events-0.22.0-alpha.3","ruma-common-0.5.0","ruma-signatures-0.7.0","ruma-common-0.4.0","ruma-identifiers-0.19.0","ruma-identifiers-0.18.1","ruma-common-0.3.1","ruma-signatures-0.6.0","ruma-common-0.3.0","ruma-identifiers-0.18.0","ruma-serde-0.3.1","ruma-client-0.5.0-alpha.1","ruma-0.0.2","ruma-push-gateway-api-0.0.1","ruma-identity-service-api-0.0.1","ruma-federation-api-0.1.0-alpha.1","ruma-client-api-0.10.0-alpha.2","ruma-appservice-api-0.2.0-alpha.2","ruma-api-0.17.0-alpha.2","ruma-events-0.22.0-alpha.2","ruma-common-0.3.0-alpha.1","ruma-signatures-0.6.0-alpha.1","ruma-identifiers-0.18.0-alpha.1","ruma-serde-0.3.0","ruma-identifiers-0.17.2","ruma-0.0.1","ruma-client-api-0.10.0-alpha.1","ruma-appservice-api-0.2.0-alpha.1","ruma-federation-api-0.0.3","ruma-api-0.17.0-alpha.1","ruma-events-0.22.0-alpha.1","ruma-serde-0.2.3","ruma-common-0.2.0","ruma-identifiers-0.17.0","0.1.0"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2024-40648.json"}}],"schema_version":"1.9.2","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:L/A:N"}]}
