CVE-2026-120061 (GCVE-0-2026-120061)

Vulnerability from cvelistv5

Published

Modified

Severity ?

7.5 (High) - CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:U/C:H/I:H/A:H

CWE

CWE-121 - Stack-based Buffer Overflow
CWE-193 - Off-by-one Error
CWE-457 - Use of Uninitialized Variable

Summary

The psqlODBC parser for ODBC escape sequences in application SQL text writes the argument offsets of a {fn} escape into a fixed 16-entry stack array without a bound and does not initialize the array. An escape with too many arguments overflows the stack, and a reference to an unsupplied argument copies arbitrary bytes into the query. The copy of a {d}, {t}, {ts}, or {escape} body also writes one byte past a 128-byte stack buffer. An application that forwards untrusted SQL text to the driver exposes its process to memory corruption. Versions before psqlODBC 18.00.0006 are affected.
