The Export Chat feature includes certain attacker-controlled elements in the generated document without sufficient escaping, leading to stored Cross site scripting (XSS). Since the Export Chat feature generates a separate document, an attacker can only inject code run from the `null` origin, restricting the impact. However, the attacker can still potentially use the XSS to leak message contents. A malicious homeserver is a potential attacker since the affected inputs are controllable server-side. This issue has been addressed in commit `22fcd34c60` which is included in release version 3.76.0. Users are advised to upgrade. The only known workaround for this issue is to disable or to not use the Export Chat feature."}],"metrics":{"cvssMetricV31":[{"source":"security-advisories@github.com","type":"Secondary","cvssData":{"version":"3.1","vectorString":"CVSS:3.1/AV:A/AC:L/PR:L/UI:R/S:C/C:H/I:N/A:N","baseScore":6.1,"baseSeverity":"MEDIUM","attackVector":"ADJACENT_NETWORK","attackComplexity":"LOW","privilegesRequired":"LOW","userInteraction":"REQUIRED","scope":"CHANGED","confidentialityImpact":"HIGH","integrityImpact":"NONE","availabilityImpact":"NONE"},"exploitabilityScore":1.7,"impactScore":4.0},{"source":"nvd@nist.gov","type":"Primary","cvssData":{"version":"3.1","vectorString":"CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:C/C:L/I:L/A:N","baseScore":5.4,"baseSeverity":"MEDIUM","attackVector":"NETWORK","attackComplexity":"LOW","privilegesRequired":"LOW","userInteraction":"REQUIRED","scope":"CHANGED","confidentialityImpact":"LOW","integrityImpact":"LOW","availabilityImpact":"NONE"},"exploitabilityScore":2.3,"impactScore":2.7}]},"weaknesses":[{"source":"security-advisories@github.com","type":"Secondary","description":[{"lang":"en","value":"CWE-79"}]}],"configurations":[{"nodes":[{"operator":"OR","negate":false,"cpeMatch":[{"vulnerable":true,"criteria":"cpe:2.3:a:matrix-react-sdk_project:matrix-react-sdk:*:*:*:*:*:node.js:*:*","versionStartIncluding":"3.32.0","versionEndExcluding":"3.76.0","matchCriteriaId":"E73DB529-1353-4F26-BEE4-8AC754FA3B70"},{"vulnerable":true,"criteria":"cpe:2.3:a:matrix-react-sdk_project:matrix-react-sdk:3.76.0:rc1:*:*:*:node.js:*:*","matchCriteriaId":"5664080A-3C0B-423C-A17D-458C8E41BBB6"},{"vulnerable":true,"criteria":"cpe:2.3:a:matrix-react-sdk_project:matrix-react-sdk:3.76.0:rc2:*:*:*:node.js:*:*","matchCriteriaId":"3128DB5F-8C45-4362-BF0E-F6F456C2E39E"}]}]}],"references":[{"url":"https://github.com/matrix-org/matrix-react-sdk/commit/22fcd34c606f32129ebc967fc21f24fb708a98b8","source":"security-advisories@github.com","tags":["Patch"]},{"url":"https://github.com/matrix-org/matrix-react-sdk/security/advisories/GHSA-c9vx-2g7w-rp65","source":"security-advisories@github.com","tags":["Third Party Advisory"]},{"url":"https://github.com/matrix-org/matrix-react-sdk/commit/22fcd34c606f32129ebc967fc21f24fb708a98b8","source":"af854a3a-2127-422b-91ae-364da2661108","tags":["Patch"]},{"url":"https://github.com/matrix-org/matrix-react-sdk/security/advisories/GHSA-c9vx-2g7w-rp65","source":"af854a3a-2127-422b-91ae-364da2661108","tags":["Third Party Advisory"]}]}}]}
