PostgreSQL is an advanced object-relational database management system (DBMS).

Security Fix(es):

  • postgresql: PostgreSQL missing validation of multibyte character length executes arbitrary code (CVE-2026-2006)
  • postgresql: PostgreSQL intarray missing validation of type of input to selectivity estimator executes arbitrary code (CVE-2026-2004)
  • postgresql: PostgreSQL pgcrypto heap buffer overflow executes arbitrary code (CVE-2026-2005)

For more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and other related information, refer to the CVE page(s) listed in the References section.
