CVE-2026-59100
LobeChat through 2.2.9 contains a broken object level authorization vulnerability that allows authenticated attackers to access and modify other users' chat-group agent data by supplying arbitrary group identifiers. Attackers can invoke the getGroupAgents, updateAgentInGroup, and removeAgentsFromGroup operations without user-scoped predicates to read agent listings, modify agent roles and ordering, and remove agents from chat groups belonging to other users.
