{"id":"CVE-2026-47234","aliases":["GHSA-mch8-wf3h-6x88"],"url":"https://o3.security/vulnerability/CVE-2026-47234","summary":"Admidio writes session IDs and auto-login cookie values to application logs","details":"Admidio is an open-source user management solution. Prior to version 5.0.10, when debug logging is enabled, `Session::setCookie()` logs full cookie values and `Session::start()` logs the current session ID. In a real Admidio deployment this includes both the active session cookie and the persistent auto-login cookie. Anyone with access to the log sink can recover live bearer-style credentials from the logs. Version 5.0.10 contains a fix.","published":"2026-08-12T13:58:11.339Z","modified":"2026-08-14T03:51:57.166064728Z","cvss":{"score":4.4,"severity":"MEDIUM","vector":"CVSS:3.1/AV:L/AC:L/PR:H/UI:N/S:U/C:H/I:N/A:N"},"epss":{"score":0.0013,"percentile":0.03084,"asOf":"2026-08-20"},"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"Packagist","name":"admidio/admidio","fixedVersion":"5.0.10"}],"fix":null,"references":[{"type":"WEB","url":"https://github.com/Admidio/admidio/blob/v5.0.9/src/Session/Entity/Session.php#L533-L540"},{"type":"WEB","url":"https://github.com/Admidio/admidio/blob/v5.0.9/src/Session/Entity/Session.php#L615-L617"},{"type":"ADVISORY","url":"https://github.com/Admidio/admidio/security/advisories/GHSA-mch8-wf3h-6x88"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/47xxx/CVE-2026-47234.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-47234"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-14T03:51:57.166064728Z"}}
