Part 2 covers remaining vectors not covered by part 1, found in a codebase audit scheduled after part 1.)\n\n### Patches\nThis is fixed in matrix-react-sdk 3.69.0\n\n### Workarounds\nNone.\n\n### References\n\n- [Release blog post](https://matrix.org/blog/2023/03/28/security-releases-matrix-js-sdk-24-0-0-and-matrix-react-sdk-3-69-0)\n- The advisory [GHSA-2x9c-qwgf-94xr](https://github.com/matrix-org/matrix-react-sdk/security/advisories/GHSA-2x9c-qwgf-94xr) ([CVE-2022-36060](https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2022-36060)) refers to an initial set of vulnerable locations discovered and patched in matrix-react-sdk 3.53.0. We opted not to disclose that advisory while we performed an audit of the codebase and are now disclosing it jointly with this one.\n\n### For more information\nIf you have any questions or comments about this advisory please email us at [security at matrix.org](mailto:security@matrix.org).",
