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."}],"affected":[{"source":"security-advisories@github.com","affectedData":[{"vendor":"matrix-org","product":"matrix-js-sdk","versions":[{"version":"< 24.1.0","status":"affected"}]}]}],"metrics":{"cvssMetricV31":[{"source":"security-advisories@github.com","type":"Secondary","cvssData":{"version":"3.1","vectorString":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:L/I:N/A:N","baseScore":5.0,"baseSeverity":"MEDIUM","attackVector":"NETWORK","attackComplexity":"LOW","privilegesRequired":"LOW","userInteraction":"NONE","scope":"CHANGED","confidentialityImpact":"LOW","integrityImpact":"NONE","availabilityImpact":"NONE"},"exploitabilityScore":3.1,"impactScore":1.4},{"source":"nvd@nist.gov","type":"Primary","cvssData":{"version":"3.1","vectorString":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N","baseScore":5.3,"baseSeverity":"MEDIUM","attackVector":"NETWORK","attackComplexity":"LOW","privilegesRequired":"NONE","userInteraction":"NONE","scope":"UNCHANGED","confidentialityImpact":"LOW","integrityImpact":"NONE","availabilityImpact":"NONE"},"exploitabilityScore":3.9,"impactScore":1.4}],"ssvcV203":[{"source":"134c704f-9b21-4f2e-91b3-4a467353bcc0","ssvcData":{"timestamp":"2025-02-06T18:45:25.233233Z","id":"CVE-2023-29529","options":[{"exploitation":"none"},{"automatable":"no"},{"technicalImpact":"partial"}],"role":"CISA Coordinator","version":"2.0.3"}}]},"weaknesses":[{"source":"security-advisories@github.com","type":"Secondary","description":[{"lang":"en","value":"CWE-862"}]},{"source":"nvd@nist.gov","type":"Primary","description":[{"lang":"en","value":"NVD-CWE-noinfo"}]}],"configurations":[{"nodes":[{"operator":"OR","negate":false,"cpeMatch":[{"vulnerable":true,"criteria":"cpe:2.3:a:matrix:javascript_sdk:*:*:*:*:*:node.js:*:*","versionEndExcluding":"24.1.0","matchCriteriaId":"F434D632-322B-4A24-A585-53A983E63A6A"}]}]}],"references":[{"url":"https://github.com/matrix-org/matrix-js-sdk/releases/tag/v24.1.0","source":"security-advisories@github.com","tags":["Release Notes"]},{"url":"https://github.com/matrix-org/matrix-js-sdk/security/advisories/GHSA-6g67-q39g-r79q","source":"security-advisories@github.com","tags":["Vendor Advisory"]},{"url":"https://github.com/matrix-org/matrix-spec-proposals/pull/3401","source":"security-advisories@github.com","tags":["Issue Tracking","Patch"]},{"url":"https://github.com/matrix-org/matrix-js-sdk/releases/tag/v24.1.0","source":"af854a3a-2127-422b-91ae-364da2661108","tags":["Release Notes"]},{"url":"https://github.com/matrix-org/matrix-js-sdk/security/advisories/GHSA-6g67-q39g-r79q","source":"af854a3a-2127-422b-91ae-364da2661108","tags":["Vendor Advisory"]},{"url":"https://github.com/matrix-org/matrix-spec-proposals/pull/3401","source":"af854a3a-2127-422b-91ae-364da2661108","tags":["Issue Tracking","Patch"]}]}}]}
