CVE-2024-47080: Matrix js sdk Matrix JavaScript SDK's Key History Vulnerability
HIGHCVE-2024-47080 is a HIGH matrix javascript sdk's key history vulnerability (CWE-287: Improper Authentication) affecting Matrix js sdk libraries in the npm ecosystem. The issue involves matrix javascript sdk's key history sharing could share keys to malicious devices. Remediation is available by upgrading affected packages to version 34.8.0.
CVE-2024-47080 at a Glance
How to Fix CVE-2024-47080
To remediate this vulnerability, upgrade all affected Matrix js sdk dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.
npm install matrix-js-sdk@34.8.0Run the following command in your project directory to verify that all resolved dependencies use the patched release:
npm ls matrix-js-sdkHow to Check if You Are Affected
To determine whether your Node.js application is affected by CVE-2024-47080, inspect your project dependencies using npm:
npm ls matrix-js-sdkAnalyze the terminal output to locate any version of Matrix js sdk in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 34.8.0), your application is affected.
Note: The npm ls matrix-js-sdk command inspects dependencies declared in your package.json and lockfile; it does not perform automated runtime dynamic scanning.
Technical Details
Vulnerability Mechanism & Technical Analysis
This vulnerability is classified under CWE-287: Improper Authentication, where when an actor claims to have a given identity, the product does not prove or insufficiently proves that the claim is correct. In Matrix js sdk, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

"details" : "### Impact\nIn matrix-js-sdk versions 9.11.0 through 34.7.0, the method `MatrixClient.sendSharedHistoryKeys` is vulnerable to interception by malicious homeservers. The method implements functionality proposed in [MSC3061](https://github.com/matrix-org/matrix-spec-proposals/pull/3061) and can be used by clients to share historical message keys with newly invited users, granting them access to past messages in the room.\n\nHowever, it unconditionally sends these \"shared\" keys to all of the invited user's devices, regardless of whether the user's cryptographic identity is verified or whether the user's devices are signed by that identity. This allows the attacker to potentially inject its own devices to receive sensitive historical keys without proper security checks.\n\nNote that this only affects clients running the SDK with the legacy crypto stack. Clients using the new Rust cryptography stack (i.e. those that call `MatrixClient.initRustCrypto()` instead of `MatrixClient.initCrypto()`) are unaffected by this vulnerability, because `MatrixClient.sendSharedHistoryKeys()` raises an exception in such environments.\n\n### Patches\nFixed in matrix-js-sdk 34.8.0 by removing the vulnerable functionality.\n\n### Workarounds\nRemove use of affected functionality from clients.\n\n### References\n- [MSC3061](https://github.com/matrix-org/matrix-spec-proposals/pull/3061)\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).",
