Capgo before 12.128.12 contains a billing authorization bypass vulnerability in the planvalid calculation that allows organizations with exhausted or expired usage credit grants to bypass billing gates. Attackers can exploit the divergence between the plugin hot-path planvalid expression and the authoritative billing gate to gain continued access to /updates, /stats, /channel_self, and attachment upload endpoints after credit depletion.
