A discovered oEmbed or image URL can bypass the `url_preview_url_blacklist` setting potentially allowing server side request forgery or bypassing network policies. Impact is limited to IP addresses allowed by the `url_preview_ip_range_blacklist` setting (by default this only allows public IPs) and by the limited information returned to the client: 1. For discovered oEmbed URLs, any non-JSON response or a JSON response which includes non-oEmbed information is discarded. 2. For discovered image URLs, any non-image response is discarded. Systems which have URL preview disabled (via the `url_preview_enabled` setting) or have not configured a `url_preview_url_blacklist` are not affected. This issue has been addressed in version 1.85.0. Users are advised to upgrade. User unable to upgrade may also disable URL previews.","state":"PUBLIC","assigner":"security-advisories@github.com","published_at":"2023-06-06 19:15:00","updated_at":"2023-06-17 03:15:00"},"problem_types":["CWE-863"],"metrics":[],"references":[{"url":"https://lists.fedoraproject.org/archives/list/package-announce@lists.fedoraproject.org/message/X6DH5A5YEB5LRIPP32OUW25FCGZFCZU2/","name":"https://lists.fedoraproject.org/archives/list/package-announce@lists.fedoraproject.org/message/X6DH5A5YEB5LRIPP32OUW25FCGZFCZU2/","refsource":"MISC","tags":[],"title":"[SECURITY] Fedora 38 Update: matrix-synapse-1.85.2-1.fc38 - package-announce - Fedora Mailing-Lists","mime":"text/html","httpstatus":"200","archivestatus":"0"},{"url":"https://github.com/matrix-org/synapse/security/advisories/GHSA-98px-6486-j7qc","name":"https://github.com/matrix-org/synapse/security/advisories/GHSA-98px-6486-j7qc","refsource":"MISC","tags":[],"title":"URL deny list bypass via oEmbed and image URLs when generating previews · Advisory · matrix-org/synapse · GitHub","mime":"text/html","httpstatus":"200","archivestatus":"404"},{"url":"https://github.com/matrix-org/synapse/pull/15601","name":"https://github.com/matrix-org/synapse/pull/15601","refsource":"MISC","tags":[],"title":"Apply url_preview_url_blacklist to oEmbed and pre-cached images by clokep · Pull Request #15601 · matrix-org/synapse · GitHub","mime":"text/html","httpstatus":"200","archivestatus":"200"},{"url":"https://www.cve.org/CVERecord?id=CVE-2023-32683","name":"CVE Program record","refsource":"CVE.ORG","tags":["canonical"]},{"url":"https://nvd.nist.gov/vuln/detail/CVE-2023-32683","name":"NVD vulnerability detail","refsource":"NVD","tags":["canonical","analysis"]}],"affected":[],"timeline":[],"solutions":[],"workarounds":[],"exploits":[],"credits":[],"nvd_cpes":[{"cve_year":"2023","cve_id":"32683","vulnerable":"1","versionEndIncluding":"","cpe1":"cpe","cpe2":"2.3","cpe3":"a","cpe4":"matrix","cpe5":"synapse","cpe6":"*","cpe7":"*","cpe8":"*","cpe9":"*","cpe10":"*","cpe11":"*","cpe12":"*","cpe13":"*"}],"vendor_comments":[],"enrichments":{"kev":null,"epss":null,"legacy_qids":[{"cve":"CVE-2023-32683","qid":"284065","title":"Fedora Security Update for matrix (FEDORA-2023-56760afca8)"},{"cve":"CVE-2023-32683","qid":"503362","title":"Alpine Linux Security Update for synapse"},{"cve":"CVE-2023-32683","qid":"506254","title":"Alpine Linux Security Update for synapse"}]},"source_records":{"cve_program":{"data_version":"4.0","data_type":"CVE","data_format":"MITRE","CVE_data_meta":{"ID":"CVE-2023-32683","ASSIGNER":"security-advisories@github.com","STATE":"PUBLIC"},"description":{"description_data":[{"lang":"eng","value":"Synapse is a Matrix protocol homeserver written in Python with the Twisted framework.
