Official description

ArcadeDB before 26.10.1 contains a remote code execution vulnerability that allows authenticated users, including read-only reader role holders, to execute Groovy code because GremlinQueryEngine.command() lacks scripting authorization checks. Attackers can submit Gremlin commands to the POST /api/v1/command/{database} endpoint when the Groovy engine is enabled to run OS commands as the server process user.
