Description

Admidio prior to version 4.1.9 is vulnerable to insufficient session expiration. In vulnerable versions, changing the password in one session does not terminate sessions logged in with the old password, which could lead to unauthorized actors maintaining access to an account.

Detection & mitigation playbook

Open-source dependency

  1. Detect

    Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for admidio/admidio, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.

  2. Fix

    Update admidio/admidio to 4.1.9 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2022-0991 is resolved across your whole dependency graph.

  3. Workarounds

    Put an independent control in front of the weakness: restrict the affected endpoint or interface to trusted networks, require an additional authentication factor or proxy-level check, and invalidate existing sessions and credentials in case the flaw has already been used.
