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-20: Improper Input Validation, where the product receives input or data, but it does not validate or incorrectly validates that the input has the properties that are required to process the data safely and correctly. 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.

Source Advisory Statement

### Impact matrix-js-sdk before 38.2.0 has insufficient validation of room predecessor links in `MatrixClient::getJoinedRooms`, allowing a remote attacker to attempt to replace a tombstoned room with an unrelated attacker-supplied room. ### Patches The issue has been patched and users should upgrade to 38.2.0. ### Workarounds Avoid using `MatrixClient::getJoinedRooms` in favour of `getRooms()` and filtering upgraded rooms separately.
