CVE-2026-42337

MaxKB is an open-source AI assistant for enterprise. MaxKB 2.8.0 and prior are vulnerable to a broken access control vulnerability in the OSS file service URL fetch API (chat/api/oss/get_url). The endpoint uses application_id from the URL path without validating ownership, allowing attackers to perform operations under other applications’ policies. This vulnerability is fixed in 2.8.1.
