JSON

A memory disclosure vulnerability was found in PostgreSQL that allows
remote users to access sensitive information by exploiting certain
aggregate function calls with ‘unknown’-type arguments. Handling
‘unknown’-type values from string literals without type designation can
disclose bytes, potentially revealing notable and confidential information.
This issue exists due to excessive data output in aggregate function calls,
enabling remote users to read some portion of system memory.
