Am I affected by CVE-2026-120064?

Check whether you run PostgreSQL psqlODBC at an affected version. Junglewise does that check for you around the clock: connect your code, cloud and domains, and it matches new vulnerabilities like this one against what you actually run and tells you when one reaches you.

CVE-2026-120064: PostgreSQL psqlODBC array index validation buffer overflow

CVE-2026-120064 · Severity: high · CVSS 7.5 · Published 2026-11-02

psqlODBC is a driver that allows applications to connect to PostgreSQL databases through the ODBC interface. Multiple functions in psqlODBC fail to validate column numbers and row indexes supplied by applications before using them as array indices, allowing out-of-bounds memory access. An application that forwards untrusted column or row numbers could be exploited to read or write memory and crash the process or execute arbitrary code.

Technical details

Multiple ODBC entry points (SQLBindCol, SQLColAttribute, SQLSetPos) accept application-supplied column or row numbers without validation, leading to out-of-bounds array access. SQLBindCol with column numbers above 32767 causes integer wrap to negative values; negative SQL_DESC_COUNT unbinds at negative indexes; SQLSetPos(SQL_ADD) does not bounds-check row numbers. The vulnerability allows remote or local code execution if an application forwards untrusted input to these functions.
