CVE-2026-75852 is an authentication bypass vulnerability in ArcadeDB versions before 26.8.1 affecting the MongoDB wire-protocol plugin. The flaw stems from a failure to enforce SASL authentication for data commands exposed through the MongoDB-compatible interface. As a result, a remote attacker can connect to the MongoDB service port and issue database operations without providing valid credentials. Exposed commands include insert, find, update, delete, and create operations, and the flaw permits access against any database reachable through the vulnerable plugin. This is a missing-authentication condition on a critical function.
