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.","cvss_v4":null,"cvss_v3":{"version":"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},"cwes":["CWE-269"],"references":["https://gitlab.com/esaqa/esaqa/security-advisories/-/blob/master/advisories/CVE-2026-117468.md","https://gitlab.com/esaqa/psono/psono-server","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"],"products":[],"source":"nvd","synced_at":"2026-10-27T06:41:43.371740013+00:00"},"epss":null,"kev":null,"osv":[],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
