Vulnerabilities 5
-
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…

High 8.2
PostgreSQL pg_trgm heap buffer overflow writes pattern onto server memory
Heap buffer overflow in PostgreSQL pg_trgm allows a database user to achieve unknown impacts via a crafted input string. The attacker has limited control over the byte patterns to be written, but we have not ruled out the viability of attacks that lead to pri…

Medium 4.3
PostgreSQL oidvector discloses a few bytes of memory
Improper validation of type "oidvector" in PostgreSQL allows a database user to disclose a few bytes of server memory. We have not ruled out viability of attacks that arrange for presence of confidential information in disclosed bytes, but they seem unlikely.…
