Arbitrary SQL execution via replacement reprocessing
Published Feb 22, 2023 · Updated Mar 10, 2025
SQL injection in Sequelize before 6.19.1 allows attackers to execute arbitrary SQL when applications combine replacements with where. Sequelize renders the where clause first, then sequelize.query reparses the generated SQL and substitutes replacement markers even inside quoted values. Exploitation requires attacker-controlled values to reach both options; executed SQL can read, alter, or delete database data.
