Technical details

The vulnerability stems from insufficient validation of room predecessor links in the MatrixClient::getJoinedRooms function. The CVSS v4.0 score is 2.7 (LOW) with the vector string CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:L/VA:N/SC:N/SI:N/SA:N/E:U. The weakness is categorized as CWE-345 (Insufficient Verification of Data Authenticity) (NVD).

Impact

The vulnerability allows a remote attacker to attempt to replace a tombstoned room with an unrelated attacker-supplied room, potentially affecting the integrity of room management in Matrix applications (GitHub Advisory).

Mitigation and workarounds

The vulnerability has been patched in version 38.2.0 of matrix-js-sdk. Users are recommended to upgrade to this version. As a workaround, users can avoid using MatrixClient::getJoinedRooms and instead use getRooms() while filtering upgraded rooms separately (GitHub Advisory).
