Description
CVE-2026-59100 is a broken object level authorization vulnerability in LobeChat through version 2.2.9. It allows authenticated attackers to access and modify chat-group agent data of other users by supplying arbitrary group identifiers. Attackers can perform operations such as getGroupAgents, updateAgentInGroup, and removeAgentsFromGroup without proper user-scoped checks, enabling unauthorized reading, modification, and removal of agents in other users' chat groups.
