CVE-2026-2006 (GCVE-0-2026-2006)

Vulnerability from cvelistv5 – Published: 2026-02-12 13:00 – Updated: 2026-02-26 14:44

Title

PostgreSQL missing validation of multibyte character length executes arbitrary code

Summary

Missing validation of multibyte character length in PostgreSQL text manipulation allows a database user to issue crafted queries that achieve a buffer overrun. That suffices to execute arbitrary code as the operating system user running the database. Versions before PostgreSQL 18.2, 17.8, 16.12, 15.16, and 14.21 are affected.

Severity ?

8.8 (High)
