An attacker needs administrator access to exploit it, and only if a user opens a file or follows a link.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2026-41662 exists.\n\nAffected packages and fixed versions:\n- admidio/admidio (Packagist): affected all versions; fixed in 5.0.9\n- admidio/admidio (Packagist): affected all versions; fixed in 5.0.9\n\nTask:\n1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.\n2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.\n3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.\n4. Run the tests and summarise what changed and why.\n5. If nothing in the project is affected, say so and change nothing.\n\nReference: https://insights.sbomify.com/CVE-2026-41662/ (Markdown: https://insights.sbomify.com/CVE-2026-41662/index.md)","id":"CVE-2026-41662","markdown":"https://insights.sbomify.com/CVE-2026-41662/index.md","name":"CVE-2026-41662","record":{"aliases":["GHSA-c7xm-r6vj-8vg6"],"analysis":{"component_type":"web_application","fix_type":"patch","impacts":["denial_of_service","security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"Admidio user management","requires_auth":"high_privilege","summary":"Administrators can remove the last remaining admin, locking the system out of administrative access due to missing validation in role membership removal.","user_interaction":"required","vuln_class":"business_logic"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[],"cvss":{"score":5.2,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:H/UI:R/S:U/C:N/I:L/A:H","version":"3.1"},"cwes":[{"id":"CWE-754","name":"Improper Check for Unusual or Exceptional Conditions"}],"description":"Admidio is an open-source user management solution. Prior to version 5.0.9, Role::stopMembership() does not verify whether removing a user from the administrator role leaves zero administrators. The deprecated Membership::stopMembership() contains this safety check, but the current code path bypasses it. Any administrator can remove the last remaining other administrator, locking the entire system out of administrative access. The exploit does not require concurrent requests; sequential removals produce the same result.
