  "title": "Unbounded query-cache growth in Ecto",
  "summary": "Ecto before 3.14.3 can retain unbounded query-cache entries and, when using ecto_sql, database prepared statements. An unauthenticated attacker may exhaust application or database memory if request-controlled JSON path values or list lengths are interpolated into affected queries that use the default query cache.",
  "mitigation": "Upgrade Ecto to version 3.14.3. Until upgraded, validate externally supplied values before interpolation, pass JSON paths as query parameters, or disable query caching for affected queries.",
