CVE-2026-56240

Capgo before 12.128.12 contains a billing authorization bypass vulnerability in the plan_valid 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 plan_valid expression and the authoritative billing gate to gain continued access to /updates, /stats, /channel_self, and attachment upload endpoints after credit depletion.
