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":"2024-07-18T17:15:05.427+00:00","modifiedAt":"2026-06-17T07:46:14.303+00:00","affected":[],"metrics":[{"system":"CVSS 3.1 · security-advisories@github.com · Secondary","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/commit/76a7052149bb8f722df12da915b3a06d19a6695a","https://github.com/matrix-org/matrix-rust-sdk/security/advisories/GHSA-4qg4-cvh2-crgg"],"sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2024-40648","license":"NIST NVD usage terms; underlying source attribution retained","enrichment":{"sourceStatus":"Deferred","weaknesses":["CWE-287"],"productCriteria":[],"sourceDates":{"published":"2024-07-18T17:15:05.427","lastModified":"2026-06-17T07:46:14.303"},"relatedAdvisories":[],"note":"NVD analysis and CPE criteria are source context, not proof that a package or your environment is affected.
