{"schemaVersion":3,"id":"CVE-2026-20149","aliases":[],"status":"published","duplicateOf":null,"title":null,"description":"A vulnerability in Cisco Webex could have allowed an unauthenticated, remote attacker to conduct a cross-site scripting (XSS) attack. Cisco has addressed this vulnerability, and no customer action is needed.\n\n This vulnerability was due to improper filtering of user-supplied input. Prior to this vulnerability being addressed, an attacker could have exploited this vulnerability by persuading a user to follow a malicious link. A successful exploit could have allowed the attacker to conduct an XSS attack against the targeted user.","dates":{"published":"2026-03-04T17:24:10.454Z","modified":"2026-03-04T20:52:26.015Z","reserved":null,"kevAdded":[],"kevDue":[]},"cvss":{"headline":{"score":6.1,"severity":"medium","version":"3.1","versionLabel":"v3.1","source":"CVE.org","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N","computed":false,"selection":"backend-summary"},"metrics":[{"version":"3.1","versionLabel":"v3.1","source":"CVE.org","score":6.1,"severity":"medium","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N","exploitability":null,"impact":null,"computed":false},{"version":"3.1","versionLabel":"v3.1","source":"NVD","score":6.1,"severity":"medium","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N","exploitability":null,"impact":null,"computed":false}]},"epss":{"probability":0.00244,"percentile":0.14536,"severity":"low","asOf":"2026-10-18T00:00:00.000Z","change":{"pp":0.00899999999999998,"baselineDate":"2026-09-18T00:00:00.000Z","baselineScore":0.00235},"history":[{"date":"2026-09-14T00:00:00.000Z","score":0.00235,"percentile":null},{"date":"2026-09-15T00:00:00.000Z","score":0.00235,"percentile":null},{"date":"2026-09-16T00:00:00.000Z","score":0.00235,"percentile":null},{"date":"2026-09-17T00:00:00.000Z","score":0.00235,"percentile":null},{"date":"2026-09-18T00:00:00.000Z","score":0.00235,"percentile":null},{"date":"2026-09-19T00:00:00.000Z","score":0.00235,"percentile":null},{"date":"2026-09-20T00:00:00.000Z","score":0.00235,"percentile":null},{"date":"2026-09-21T00:00:00.000Z","score":0.00235,"percentile":null},{"date":"2026-09-22T00:00:00.000Z","score":0.00235,"percentile":null},{"date":"2026-09-23T00:00:00.000Z","score":0.00235,"percentile":null},{"date":"2026-09-24T00:00:00.000Z","score":0.00235,"percentile":null},{"date":"2026-09-25T00:00:00.000Z","score":0.00235,"percentile":null},{"date":"2026-09-26T00:00:00.000Z","score":0.00235,"percentile":null},{"date":"2026-09-27T00:00:00.000Z","score":0.00235,"percentile":null},{"date":"2026-09-28T00:00:00.000Z","score":0.00235,"percentile":null},{"date":"2026-09-29T00:00:00.000Z","score":0.00235,"percentile":null},{"date":"2026-09-30T00:00:00.000Z","score":0.00235,"percentile":null},{"date":"2026-10-01T00:00:00.000Z","score":0.00235,"percentile":null},{"date":"2026-10-02T00:00:00.000Z","score":0.00244,"percentile":null},{"date":"2026-10-03T00:00:00.000Z","score":0.00244,"percentile":null},{"date":"2026-10-04T00:00:00.000Z","score":0.00244,"percentile":null},{"date":"2026-10-05T00:00:00.000Z","score":0.00244,"percentile":null},{"date":"2026-10-06T00:00:00.000Z","score":0.00244,"percentile":null},{"date":"2026-10-07T00:00:00.000Z","score":0.00244,"percentile":null},{"date":"2026-10-08T00:00:00.000Z","score":0.00244,"percentile":null},{"date":"2026-10-09T00:00:00.000Z","score":0.00244,"percentile":null},{"date":"2026-10-10T00:00:00.000Z","score":0.00244,"percentile":null},{"date":"2026-10-11T00:00:00.000Z","score":0.00244,"percentile":null},{"date":"2026-10-12T00:00:00.000Z","score":0.00244,"percentile":null},{"date":"2026-10-13T00:00:00.000Z","score":0.00244,"percentile":null},{"date":"2026-10-14T00:00:00.000Z","score":0.00244,"percentile":null},{"date":"2026-10-15T00:00:00.000Z","score":0.00244,"percentile":null},{"date":"2026-10-16T00:00:00.000Z","score":0.00244,"percentile":null},{"date":"2026-10-17T00:00:00.000Z","score":0.00244,"percentile":null},{"date":"2026-10-18T00:00:00.000Z","score":0.00244,"percentile":0.14536}],"last30":[{"date":"2026-09-18T00:00:00.000Z","score":0.00235,"percentile":null},{"date":"2026-09-19T00:00:00.000Z","score":0.00235,"percentile":null},{"date":"2026-09-20T00:00:00.000Z","score":0.00235,"percentile":null},{"date":"2026-09-21T00:00:00.000Z","score":0.00235,"percentile":null},{"date":"2026-09-22T00:00:00.000Z","score":0.00235,"percentile":null},{"date":"2026-09-23T00:00:00.000Z","score":0.00235,"percentile":null},{"date":"2026-09-24T00:00:00.000Z","score":0.00235,"percentile":null},{"date":"2026-09-25T00:00:00.000Z","score":0.00235,"percentile":null},{"date":"2026-09-26T00:00:00.000Z","score":0.00235,"percentile":null},{"date":"2026-09-27T00:00:00.000Z","score":0.00235,"percentile":null},{"date":"2026-09-28T00:00:00.000Z","score":0.00235,"percentile":null},{"date":"2026-09-29T00:00:00.000Z","score":0.00235,"percentile":null},{"date":"2026-09-30T00:00:00.000Z","score":0.00235,"percentile":null},{"date":"2026-10-01T00:00:00.000Z","score":0.00235,"percentile":null},{"date":"2026-10-02T00:00:00.000Z","score":0.00244,"percentile":null},{"date":"2026-10-03T00:00:00.000Z","score":0.00244,"percentile":null},{"date":"2026-10-04T00:00:00.000Z","score":0.00244,"percentile":null},{"date":"2026-10-05T00:00:00.000Z","score":0.00244,"percentile":null},{"date":"2026-10-06T00:00:00.000Z","score":0.00244,"percentile":null},{"date":"2026-10-07T00:00:00.000Z","score":0.00244,"percentile":null},{"date":"2026-10-08T00:00:00.000Z","score":0.00244,"percentile":null},{"date":"2026-10-09T00:00:00.000Z","score":0.00244,"percentile":null},{"date":"2026-10-10T00:
