CVE-2026-13713: Ruby St Table Uaf
An element retrieved or deleted from an st_table is immediately freed. If secondary references to this element exist (e.g., on a parser stack), this causes a use-after-free and potential double-free. Verify ownership before freeing, or append the node to a retirement list for delayed garbage collection.
