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.","state":0,"publishedAt":"2024-07-18T16:45:56.321+00:00","modifiedAt":"2024-08-02T04:33:11.826+00:00","affected":[{"ecosystem":"Vendor product","name":"matrix-rust-sdk","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"matrix-org\",\n                    \"product\": \"matrix-rust-sdk\",\n                    \"versions\": [\n                        {\n                            \"version\": \"< 0.7.2\",\n                            \"status\": \"affected\"\n                        }\n                    ]\n                }"}],"metrics":[{"system":"CVSS 3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:L/A:N","score":5.4,"severity":"MEDIUM"}],"references":["https://github.com/matrix-org/matrix-rust-sdk/security/advisories/GHSA-4qg4-cvh2-crgg","https://github.com/matrix-org/matrix-rust-sdk/commit/76a7052149bb8f722df12da915b3a06d19a6695a"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2024-40648","license":"CVE Program Terms of Use","key":"cve-program:CVE-2024-40648","identifiers":["CVE-2024-40648"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
