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.","state":0,"publishedAt":"2026-10-27T05:41:30.742+00:00","modifiedAt":"2026-10-27T05:59:08.92+00:00","affected":[{"ecosystem":"Vendor product","name":"Psono","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"esaqa GmbH\",\n                    \"product\": \"Psono\",\n                    \"repo\": \"https://gitlab.com/esaqa/psono/psono-server\",\n                    \"modules\": [\n                        \"Psono Server Community Edition\",\n                        \"Psono Server Enterprise Edition\"\n                    ],\n                    \"programFiles\": [\n                        \"psono/restapi/views/device_code_claim.py\",\n                        \"psono/restapi/views/device_code_token.py\"\n                    ],\n                    \"versions\": [\n                        {\n                            \"status\": \"affected\",\n                            \"version\": \"5.3.5\",\n                            \"lessThan\": \"7.2.4\",\n                            \"versionType\": \"semver\"\n                        }\n                    ],\n                    \"defaultStatus\": \"unaffected\"\n                }"}],"metrics":[{"system":"CVSS 3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:H/A:N","score":6.5,"severity":"MEDIUM"}],"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"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-117468","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-117468","identifiers":["CVE-2026-117468"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
