What is CVE-2026-65831?

ArcadeDB, a multi-model database management system, has a vulnerability that allows reader-role users to exploit certain functions and perform unauthorized access. Specifically, the PolyglotQueryEngine components do not enforce necessary database-administrator permissions, enabling users to execute commands on the database and read files outside its designated scope. This flaw can potentially lead to the exposure of sensitive information, although process creation is not permitted. The vulnerability has been addressed in version 26.7.1, emphasizing the need for users to update their systems to mitigate risk.
