ETK-2026-2524Zero's internal tracking ID, independent of the CVE number.
validatedZero produced an exploit or a check.description
SurrealDB versions 3.2.0 through before 3.3.0 are affected when MCP HTTP uses JWT or Bearer access methods. An authenticated user who obtains another user's MCP session ID may invoke MCP tools with the other user's permissions because the per-request subject check does not distinguish users of the same access method.
mitigation
Upgrade the Rust surrealdb package to version 3.3.0 or later. Until upgraded, restrict access to the MCP HTTP endpoint and protect MCP session IDs from disclosure.
fixed in 3.3.0
outcome
Check only, differential: the check fires on the vulnerable build and is silent on the patched one.
