Technical description

MaxKB is an open-source AI assistant for enterprise. In 2.10.2-lts and earlier, management chat-record routes authorize the path application_id but load records using global chat_id and chat_record_id values without confirming that the chat belongs to the authorized application. A normal user in the same workspace who knows the chat_id of a persisted non-debug record for a victim's published application can place it under a separate attacker-owned application path to read victim chat records. An attacker with an owned knowledge base and document can also use add_knowledge to copy victim answers while updating the victim record's improve_paragraph_id_list. No fixed version is available as of this review.

———MaxKB is an open-source AI assistant for enterprise. In 2.10.2-lts and earlier, a normal user in the same workspace can obtain another user's application_id from the homepage application question-ranking endpoint when the published victim application has ranking activity in the selected date range and the attacker knows or guesses its name, even though direct application detail and debug-open routes deny access. An attacker who can create and publish a workflow application can place the disclosed identifier in an attacker-owned workflow application-node, trigger that workflow, receive output generated by the victim application, and create durable application_chat and application_chat_record rows under the victim application because save and runtime paths do not verify permission to use the referenced application. No fixed version is available as of this review.13h CVE-2026-775185.0 MED

———MaxKB is an open-source AI assistant for enterprise. In 2.10.2-lts and earlier, a normal workspace user who knows another user's active MCP tool_id in the same workspace can retrieve the hidden tool through the tool-detail route because it does not apply the per-resource authorization used by the list route. The response includes Tool.code, which may contain MCP server configuration and headers, and an attacker who can create or edit an attacker-owned workflow can place the same foreign mcp_tool_id in a workflow mcp-node so workflow debug uses the owner's MCP configuration without verifying permission to use that tool. No fixed version is available as of this review.13h CVE-2026-775175.4 MED

———MaxKB is an open-source AI assistant for enterprise. From version 2.0.0 through 2.10.2-lts, document and paragraph operate routes authorize only knowledge_id in the request path, then query the target Document by document_id or Paragraph by paragraph_id without confirming that the object belongs to that knowledge base. A normal workspace user with a known victim document or paragraph UUID can use an attacker-owned knowledge-base path to read or modify content in another user's knowledge base. No fixed version is available as of this review.13h CVE-2026-775165.4 MED

—

———MaxKB is an open-source AI assistant for enterprise. From version 2.0.0 through 2.9.2, a lowest-role workspace member denied access to a tool by WorkspaceUserResourcePermission can still bind its identifier through tool_ids, skill_tool_ids, or mcp_tool_ids and execute it through the agent or workflow dispatch path. The dispatch path does not reapply the per-tool grant enforced by dedicated tool routes, and tool execution decrypts server-side init_params, allowing the caller to receive credentials carried by the denied tool. No fixed version is available as of this review.13h CVE-2026-945018.8 HIG

——0jshERP through 3.6 contains an authorization bypass vulnerability in the userBusiness CRUD endpoints that allows authenticated users to create, modify, or delete authorization-relation rows without privilege checks. Attackers can manipulate user-role mappings and access controls to escalate privileges, strip access from other accounts, or modify role-function relationships for any user in the tenant.15h CVE-2026-944968.3 HIG

—

——0jshERP through 3.6 fails to validate caller permissions in role management endpoints, allowing authenticated users to modify any role's data scope or delete roles. Attackers can exploit the /role/update and /role/delete endpoints to escalate privileges, change data visibility to all data, and access all business records in the tenant.14h
