Authentication tokens used by the web \nmanagement interface are insufficiently protected during client-side \nsession handling, which may allow an attacker with access to exposed \nsession information to obtain and reuse a valid token. Successful \nexploitation could allow an attacker to impersonate an authenticated \nuser and gain unauthorized access to device management functionality.","published":"2026-08-28T00:18:14.430","modified":"2026-08-28T00:18:14.430","cvss":{"score":9.8,"severity":"CRITICAL","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H"},"epss":null,"cisaKev":null,"exploitsKnown":null,"affectedPackages":[],"fix":null,"references":[{"type":"WEB","url":"https://github.com/cisagov/CSAF/blob/develop/csaf_files/OT/white/2026/icsa-26-237-06.json"},{"type":"WEB","url":"https://www.cisa.gov/news-events/ics-advisories/icsa-26-237-06"}],"provenance":{"sources":["OSV.dev","NVD","FIRST.org (EPSS)"],"lastVerified":"2026-08-28T00:18:14.430"}}
