Detailsinfo

Affected by this vulnerability is the function SetServerSettingTool.execute of the component Set Server Setting Tool. The manipulation with an unknown input leads to a authorization vulnerability.

As an impact it is known to affect confidentiality, integrity, and availability. The summary by CVE is:

ArcadeDB versions 26.4.2 through 26.7.3 contain an authorization bypass vulnerability in the set_server_setting MCP server-level tool. SetServerSettingTool.execute() gates only on the global allowAdmin flag and never checks the caller's role, so in an MCP deployment with allowAdmin=true and a non-root allowedUsers set, any authenticated read-only user can invoke set_server_setting to modify server GlobalConfiguration, enabling configuration tampering or denial of service. The issue is fixed in 26.8.1.
