An attacker present in a room where an MSC3401 group call is taking place can eavesdrop on the video and audio of participants using matrix-js-sdk, without their knowledge. To affected matrix-js-sdk users, the attacker will not appear to be participating in the call. This attack is possible because matrix-js-sdk's group call implementation accepts incoming direct calls from other users, even if they have not yet declared intent to participate in the group call, as a means of resolving a race condition in call setup. Affected versions do not restrict access to the user's outbound media in this case. Legacy 1:1 calls are unaffected. This is fixed in matrix-js-sdk 24.1.0. As a workaround, users may hold group calls in private rooms where only the exact users who are expected to participate in the call are present."}], "lastModified": "2024-11-21T07:57:14.377", "configurations": [{"nodes": [{"negate": false, "cpeMatch": [{"criteria": "cpe:2.3:a:matrix:javascript_sdk:*:*:*:*:*:node.js:*:*", "vulnerable": true, "matchCriteriaId": "F434D632-322B-4A24-A585-53A983E63A6A", "versionEndExcluding": "24.1.0"}], "operator": "OR"}]}], "sourceIdentifier": "security-advisories@github.com"}
