CVE-2026-16239

CVE-2026-16239 is a PostgreSQL vulnerability involving type confusion in the portal/cursor lifecycle. An attacker can execute arbitrary code as the database OS user by re-creating a cursor/portal with different types. Affected versions are PostgreSQL

CVE-2026-16239 PostgreSQL type confusion in cursor CLOSE + DECLARE executes arbitrary code

Type confusion in PostgreSQL "portal"/cursor lifecycle allows a user to execute arbitrary code as the operating system user running the database, via re-creation of a cursor or other portal with different types. Versions before PostgreSQL 18.5, 17.11, 16.15, 15.19, and 14.24 are affected...

CVE-2026-16241

Integer underflow in PostgreSQL ECPG allows a database server administrator to achieve temporary denial of service against the ECPG client via sending a bytea value lacking the mandatory prefix. The client overwrites a huge memory region with bytes outside attacker knowledge or control. This...
