Prior to version 3.71.0, plain text messages containing HTML tags are rendered as HTML in the search results. To exploit this, an attacker needs to trick a user into searching for a specific message containing an HTML injection payload. No cross-site scripting attack is possible due to the hardcoded content security policy. Version 3.71.0 of the SDK patches over the issue. As a workaround, restarting the client will clear the HTML injection.","references":[{"reference_url":"https://api.first.org/data/v1/epss?cve=CVE-2023-30609","reference_id":"","reference_type":"","scores":[{"value":"0.00575","scoring_system":"epss","scoring_elements":"0.69194","published_at":"2026-06-09T12:55:00Z"},{"value":"0.00575","scoring_system":"epss","scoring_elements":"0.69175","published_at":"2026-06-08T12:55:00Z"},{"value":"0.00575","scoring_system":"epss","scoring_elements":"0.69199","published_at":"2026-06-06T12:55:00Z"},{"value":"0.00575","scoring_system":"epss","scoring_elements":"0.6919","published_at":"2026-06-07T12:55:00Z"}],"url":"https://api.first.org/data/v1/epss?cve=CVE-2023-30609"},{"reference_url":"https://github.com/matrix-org/matrix-react-sdk","reference_id":"","reference_type":"","scores":[{"value":"8.2","scoring_system":"cvssv3.1","scoring_elements":"CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:C/C:H/I:L/A:L"},{"value":"HIGH","scoring_system":"generic_textual","scoring_elements":""}],"url":"https://github.com/matrix-org/matrix-react-sdk"},{"reference_url":"https://github.com/matrix-org/matrix-react-sdk/commit/bf182bc94556849d7acdfa0e5fdea2aa129ea826","reference_id":"","reference_type":"","scores":[{"value":"5.4","scoring_system":"cvssv3.1","scoring_elements":"CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:C/C:N/I:L/A:L"},{"value":"8.2","scoring_system":"cvssv3.1","scoring_elements":"CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:C/C:H/I:L/A:L"},{"value":"HIGH","scoring_system":"generic_textual","scoring_elements":""},{"value":"Track","scoring_system":"ssvc","scoring_elements":"SSVCv2/E:N/A:N/T:P/P:M/B:A/M:M/D:T/2025-02-03T17:54:49Z/"}],"url":"https://github.com/matrix-org/matrix-react-sdk/commit/bf182bc94556849d7acdfa0e5fdea2aa129ea826"},{"reference_url":"https://github.com/matrix-org/matrix-react-sdk/releases/tag/v3.71.0","reference_id":"","reference_type":"","scores":[{"value":"5.4","scoring_system":"cvssv3.1","scoring_elements":"CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:C/C:N/I:L/A:L"},{"value":"8.2","scoring_system":"cvssv3.1","scoring_elements":"CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:C/C:H/I:L/A:L"},{"value":"HIGH","scoring_system":"generic_textual","scoring_elements":""},{"value":"Track","scoring_system":"ssvc","scoring_elements":"SSVCv2/E:N/A:N/T:P/P:M/B:A/M:M/D:T/2025-02-03T17:54:49Z/"}],"url":"https://github.com/matrix-org/matrix-react-sdk/releases/tag/v3.71.0"},{"reference_url":"https://nvd.nist.gov/vuln/detail/CVE-2023-30609","reference_id":"CVE-2023-30609","reference_type":"","scores":[{"value":"8.2","scoring_system":"cvssv3.1","scoring_elements":"CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:C/C:H/I:L/A:L"},{"value":"HIGH","scoring_system":"generic_textual","scoring_elements":""}],"url":"https://nvd.nist.gov/vuln/detail/CVE-2023-30609"},{"reference_url":"https://github.com/advisories/GHSA-xv83-x443-7rmw","reference_id":"GHSA-xv83-x443-7rmw","reference_type":"","scores":[{"value":"HIGH","scoring_system":"cvssv3.1_qr","scoring_elements":""}],"url":"https://github.com/advisories/GHSA-xv83-x443-7rmw"},{"reference_url":"https://github.com/matrix-org/matrix-react-sdk/security/advisories/GHSA-xv83-x443-7rmw","reference_id":"GHSA-xv83-x443-7rmw","reference_type":"","scores":[{"value":"5.4","scoring_system":"cvssv3.1","scoring_elements":"CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:C/C:N/I:L/A:L"},{"value":"8.2","scoring_system":"cvssv3.1","scoring_elements":"CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:C/C:H/I:L/A:L"},{"value":"HIGH","scoring_system":"cvssv3.1_qr","scoring_elements":""},{"value":"HIGH","scoring_system":"generic_textual","scoring_elements":""},{"value":"Track","scoring_system":"ssvc","scoring_elements":"SSVCv2/E:N/A:N/T:P/P:M/B:A/M:M/D:T/2025-02-03T17:54:49Z/"}],"url":"https://github.com/matrix-org/matrix-react-sdk/security/advisories/GHSA-xv83-x443-7rmw"}],"fixed_packages":[{"url":"http://public2.vulnerablecode.io/api/packages/64960?format=json","purl":"pkg:npm/matrix-react-sdk@3.71.0","is_vulnerable":true,"affected_by_vulnerabilities":[{"vulnerability":"VCID-4zyy-8bxy-9ygp"},{"vulnerability":"VCID-bs36-6f91-euhe"},{"vulnerability":"VCID-ttnv-yue6-1bhr"}],"resource_url":"http://public2.vulnerablecode.io/packages/pkg:npm/matrix-react-sdk@3.71.0"}],"aliases":["CVE-2023-30609","GHSA-xv83-x443-7rmw"],"risk_score":4.0,"exploitability":"0.5","weighted_severity":"8.0","resource_url":"http://public2.vulnerablecode.io/vulnerabilities/VCID-v528-sdjx-h3d7"}],"fixing_vulnerabilities":[],"risk_score":"4.0","resource_url":"http://public2.vulnerablecode.io/packages/pkg:npm/matrix-react-sdk@0.12.4-rc.1"}
