An authenticated remote attacker holding a restricted API key-derived session could claim an attacker-controlled device code and obtain a full read-write session valid for up to 365 days, bypassing the original token's scope and lifetime restrictions. This did not bypass two-factor authentication or directly disclose plaintext secrets.","severity":"medium","score":6.5,"published":"2026-10-27T05:41:30.742Z","modified":"2026-10-27T05:59:08.920Z","withdrawn":false,"knownExploited":false,"affected":[],"references":["https://gitlab.com/esaqa/psono/psono-server/-/blob/v7.2.3/psono/restapi/views/device_code_claim.py","https://gitlab.com/esaqa/psono/psono-server/-/commit/19ed5a192c704fece1645d946b6f4c36045bacbe","https://gitlab.com/esaqa/psono/psono-server/-/releases/v7.2.4","https://gitlab.com/esaqa/psono/psono-server","https://gitlab.com/esaqa/esaqa/security-advisories/-/blob/master/advisories/CVE-2026-117468.md"],"sources":[{"name":"CVE","id":"CVE-2026-117468","modified":"2026-10-27T05:59:08.920Z","url":"https://www.cve.org/CVERecord?id=CVE-2026-117468"}],"assessments":[{"source":"esaqa","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:H/A:N","score":6.5}],"sourceAffected":[],"kev":{"status":"not-listed","checkedAt":"2026-10-28T22:25:35.093Z"},"coverage":[{"source":"NVD","status":"not-checked"},{"source":"GHSA","status":"not-checked"},{"source":"EUVD","status":"not-checked"},{"source":"EPSS","status":"not-checked"}],"evidence":[]}
