Description

MoinMoin 1.6.2 and 1.7 does not properly enforce ACL checks when acl_hierarchic is set to True, which might allow remote attackers to bypass intended access restrictions, a different vulnerability than CVE-2008-1937.

Detection & mitigation playbook

Open-source dependency

  1. Detect

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

  2. Fix

    Update moin to 1.7.1-1 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2008-6603 is resolved across your whole dependency graph.

  3. Workarounds

    If you can't upgrade right away: gate or disable the affected feature, validate untrusted input at the boundary, and avoid passing attacker-controlled data into the vulnerable path. O3's runtime protection blocks exploitation in production as an interim safeguard until the upgrade lands.
