Published:November 12, 2026

Improper null termination in PostgreSQL array element assignment allows a database user to disclose server memory, via changing the final byte of a fixed-length name value to a nonzero byte and passing it to code that treats the value as a C string. Versions before PostgreSQL 18.7, 17.12, 16.16, 15.20, and 14.25 are affected.
