Oj - Stack Buffer Overflow in Oj::Doc#each_child via Deeply Nested Input

Summary Oj::Doceachchild, when invoked recursively over a deeply nested JSON document, overflows a fixed-size stack buffer and aborts the process. This is a denial of service reachable from untrusted JSON. Impact Reliable denial of service: any endpoint that calls Oj::Doc.openuntrusted |d|...

PT-2026-53787

An authenticated user could crash a SurrealDB server with a single query containing a long chain of operators. Such a query — for example RETURN 1 + 1 + 1 + ... with tens of thousands of terms — is parsed into an expression tree one level deep per operator. Because the chain is flat and the pratt...

CVE-2026-50194

Steeltoe CVE-2026-50194 affects management endpoints when configured to listen on an alternate port. Versions 3.2.2–3.3.0 and 4.1.0 use the Host header to gate access instead of the socket port, enabling port-isolation bypass. Patches are in 3.4.0 and 4.2.0. If upgrading isn’t possible, apply exp...
