It is based on MatrixSDK. Prior to version 1.9.7, events encrypted using Megolm for which trust could not be established did not get decorated accordingly (with warning shields). Therefore a malicious homeserver could inject messages into the room without the user being alerted that the messages were not sent by a verified group member, even if the user has previously verified all group members. This issue has been patched in Element iOS 1.9.7. There are currently no known workarounds.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:N","score":6.5},"cwes":["CWE-357"],"references":["https://github.com/vector-im/element-ios/releases/tag/v1.9.7","https://github.com/vector-im/element-ios/security/advisories/GHSA-fm8m-99j7-323g","https://github.com/vector-im/element-ios/releases/tag/v1.9.7","https://github.com/vector-im/element-ios/security/advisories/GHSA-fm8m-99j7-323g"],"products":["element:element"],"source":"nvd","synced_at":"2026-10-19T21:37:08.729216836+00:00"},"epss":{"cve":"CVE-2022-41904","score":0.00465,"percentile":0.40299,"date":"2026-10-31"},"kev":null,"osv":[],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
