Prototype pollution via unsafe nested table keys
Published May 29, 2024 · Updated Aug 1, 2024
Prototype pollution in Sidorares MySQL2 before 3.9.8 allows remote attackers to alter object prototypes through crafted result metadata. The text and binary row parsers used unvalidated table names and concatenated nestTables keys when assigning properties on result objects. Exploitation requires nestTables and attacker control over returned table or field names; polluted properties can alter application data or interrupt service.
