What is CVE-2026-82869?

ToolJet Database versions earlier than 3.16.44 are susceptible to a privilege escalation vulnerability within the join_tables endpoint. This flaw allows any authenticated user to gain JOIN_TABLES capabilities without proper validation of user roles or workspace memberships. By leveraging this vulnerability, attackers can potentially access arbitrary tables across different workspaces by simply providing the victim's workspace identifiers while using their own credentials.
