CVE-2026-108756
Abilityai Trinity through 0.9.5 contains a missing authorization vulnerability in the Telegram router that allows agent-scoped MCP API keys to perform human-only binding operations.
Does this matter?
Lower severity and a low EPSS score (0.22%). Track it; it rarely justifies an emergency change on its own.
Description
Abilityai Trinity through 0.9.5 contains a missing authorization vulnerability in the Telegram router that allows agent-scoped MCP API keys to perform human-only binding operations. Attackers controlling an agent, typically via prompt injection, can send messages through the owner's bot token, replace the binding with their own token, or delete it.
