CVE-2026-114056 Details
Description
ArcadeDB from 26.8.1 before 26.10.1 contains an authorization bypass vulnerability that allows read-only users to modify edge type lightweight and unique schema flags without UPDATE_SCHEMA permission. Attackers can send a bare ALTER TYPE edgeType WITH lightweight = true command over the HTTP, gRPC, or Bolt command API to persistently alter edge storage declarations.
A vulnerability exists in ArcadeDB versions 26.8.1 prior to 26.10.1, allowing read-only users to bypass authorization and modify edge type schema flags. Specifically, users can alter the 'lightweight' and 'unique' attributes of edge types without the necessary 'UPDATE_SCHEMA' permission. This is achieved by sending a bare 'ALTER TYPE <edgeType> WITH lightweight = true' command through the HTTP, gRPC, or Bolt command APIs. The vulnerability arises because the schema mutation permissions are not properly enforced for these specific edge type modifications, enabling unauthorized changes that persist across server restarts.
Users are advised to upgrade to ArcadeDB version 26.10.1, where this vulnerability has been addressed.
