Last modified
CVE-2026-2006 is a high-severity vulnerability rated 8.8/10 on the CVSS scale. 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. EPSS estimates a 0.66% chance of exploitation in the next 30 days.
Description
