Vulnerabilities 3
-
High 8.8
PostgreSQL intarray missing validation of type of input to selectivity estimator executes arbitrary code
Missing validation of type of input in PostgreSQL intarray extension selectivity estimator function allows an object creator to execute arbitrary code as the operating system user running the database. Versions before PostgreSQL 18.2, 17.8, 16.12, 15.16, and …

High 8.8CVE-2026-2005 Public exploit
PostgreSQL pgcrypto heap buffer overflow executes arbitrary code
Heap buffer overflow in PostgreSQL pgcrypto allows a ciphertext provider 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.

High 8.8
PostgreSQL missing validation of multibyte character length executes arbitrary code
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…
