Weaponization
Public repositories whose name or description references CVE-2010-0806, found via a live GitHub search at request time. These are community-sourced signals, not a verified working exploit - cross-check each one before relying on it, and treat higher star counts and recent activity as (weak) corroboration, not proof.
No public GitHub repositories referencing CVE-2010-0806 were found at last check. Absence here is not proof no exploit exists - see the references below for vendor advisories and write-ups.
