CVE-2026-77525

medium

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.
