CVE-2026-59100Public exploitNetwork attack vector

Cross-user agent access and modification via unscoped queries

Published Jul 2, 2026 · Updated Jul 2, 2026

Authorization bypass in LobeHub 2.2.9 and earlier allows remote authenticated users to read and alter other users' chat-group agent data. The getGroupAgents, updateAgentInGroup, and removeAgentsFromGroup paths query junction rows by client-supplied identifiers without caller-ownership predicates. Any authenticated user on a multi-user deployment who obtains another group's UUID can list its agents, change roles or ordering, and remove memberships.
