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":null,"modifiedAt":null,"affected":[],"metrics":[{"system":"EUVD 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":null}],"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://euvd.enisa.europa.eu/vulnerability/EUVD-2024-2249","license":"ENISA EUVD · source terms and attribution apply","enrichment":{"sourceStatus":null,"weaknesses":[],"productCriteria":[],"sourceDates":{"datePublished":"Jul 18, 2024, 4:45:56 PM","dateUpdated":"Aug 2, 2024, 4:33:11 AM"},"relatedAdvisories":[{"id":"openSUSE-SU-2024:14224-1","title":"cargo-audit-advisory-db-20240730-1.1 on GA media","vulnerabilityIds":["CVE-2024-40648"]}],"note":"EUVD source date text has no stated timezone and is retained without inventing a UTC instant.
