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."}], "lastModified": "2024-11-21T08:11:19.710", "configurations": [{"nodes": [{"negate": false, "cpeMatch": [{"criteria": "cpe:2.3:a:matrix-react-sdk_project:matrix-react-sdk:*:*:*:*:*:node.js:*:*", "vulnerable": true, "matchCriteriaId": "E73DB529-1353-4F26-BEE4-8AC754FA3B70", "versionEndExcluding": "3.76.0", "versionStartIncluding": "3.32.0"}, {"criteria": "cpe:2.3:a:matrix-react-sdk_project:matrix-react-sdk:3.76.0:rc1:*:*:*:node.js:*:*", "vulnerable": true, "matchCriteriaId": "5664080A-3C0B-423C-A17D-458C8E41BBB6"}, {"criteria": "cpe:2.3:a:matrix-react-sdk_project:matrix-react-sdk:3.76.0:rc2:*:*:*:node.js:*:*", "vulnerable": true, "matchCriteriaId": "3128DB5F-8C45-4362-BF0E-F6F456C2E39E"}], "operator": "OR"}]}], "sourceIdentifier": "security-advisories@github.com"}
