CVE-2026-119371SQLite before 3.54.0 Stack Exhaustion via CTE Chain in selectExpander()

Descripción

SQLite before 3.54.0 contains a stack exhaustion vulnerability that allows attackers to bypass the SQLITE_LIMIT_EXPR_DEPTH nesting limit because common table expressions are not counted against it. Attackers can supply a WITH clause chaining tens of thousands of CTEs, via plain SQL or a view in an untrusted database file, causing unbounded selectExpander() recursion that crashes the process.
