Descripción técnica

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.

CVE-2026-945364.3 MED
—
———lamp-cloud through 5.10.0 fails to validate the employeeId parameter in the /anyone/visible/resource endpoint, allowing authenticated users to read any employee's roles and permissions. Attackers can supply arbitrary employeeId values to enumerate other employees' role codes, permission codes, and complete front-end router trees without authorization checks.12hCVE-2026-945357.1 ALT
—
———lamp-cloud through 5.10.0 contains an authorization bypass vulnerability in the deleteMyNotice endpoint that allows authenticated users to delete other users' notifications. Attackers can call the DELETE /anyone/extendNotice/deleteMyNotice endpoint with arbitrary notice IDs to permanently remove notifications belonging to other users without recipient validation.12hCVE-2026-945347.1 ALT
—
———lamp-cloud through 5.10.0 fails to validate user identity in PUT /anyone/baseInfo and PUT /anyone/avatar endpoints, allowing authenticated attackers to modify arbitrary user profiles. Attackers can supply target user IDs in request bodies to rewrite profile fields including nickname, ID card, sex, nation, education, work description, and avatar attachments of other users.12hCVE-2026-945336.5 MED
—
———lamp-cloud through 5.10.0 contains an authorization bypass vulnerability in FileAnyoneController that allows authenticated users to download arbitrary attachments. Attackers can retrieve other users' stored files by supplying valid attachment identifiers to the /anyone/file/down and /anyone/file/download endpoints, as the application never validates file ownership against the created_by column.12hCVE-2026-945326.5 MED
—
———lamp-cloud through 5.10.0 contains an authorization bypass vulnerability in the getUserInfoById endpoint that allows authenticated users to read any other user's full profile. Attackers can iterate the userId parameter to harvest sensitive user information including mobile numbers, email addresses, national identity card numbers, and WeChat and DingTalk OpenIDs.12hCVE-2026-799176.5 MED
—
———MaxKB is an open-source AI assistant for enterprise. In 2.7.0 through 2.10.4-lts, POST /chat/api/{application_id}/chat/{chat_id}/share_chat verifies that a conversation exists but does not verify that it belongs to the authenticated chat_user_id or to the application bound to the caller's token. An attacker with any chat token and a known victim chat_id can create an unauthenticated public ChatShareLink exposing the victim's conversation and can create PublicFileAccess state that makes associated files retrievable without credentials, with no available revoke path. No fixed version is available as of this review.13h
