CVE-2026-116315

PostgreSQL tsvector_delete() heap buffer overflow executes arbitrary code

Heap-based buffer overflow in PostgreSQL tsvector_delete() allows a database user to execute arbitrary code as the operating system user running the database, via a tsvector whose lexeme data uses a nonstandard but valid ordering that requires additional alignment padding in the result. Versions before PostgreSQL 18.7, 17.12, 16.16, 15.20, and 14.25 are affected.

Missing authorization in PostgreSQL logical replication allows a compromised publisher to execute arbitrary code as the operating system user running the superuser-owned subscription, via naming a system catalog as a replication target. Only subscriptions owned by a superuser are vulnerable. Versions before PostgreSQL 18.7, 17.12, 16.16, 15.20, and 14.25 are affected.

SQL injection in PostgreSQL extension-script substitutions allows an attacker with database-level CREATE privilege to execute arbitrary code as the bootstrap superuser, via a schema or owner name containing newlines or other special substrings. This is similar to CVE-2023-39417, but it requires a non-bundled extension with a vulnerable script pattern. Versions before PostgreSQL 18.7, 17.12, 16.16, 15.20, and 14.25 are affected.

PostgreSQL security-restricted operations can create types in pg_temp, which later queries of the session find

Improper protection of alternate path in PostgreSQL security-restricted operations allows an object creator to execute arbitrary SQL as the operation's caller, via a domain, enum, or range type created in pg_temp. The victim session must later run a query containing an unqualified type name, e.g. "SELECT '1'::bigint"; autovacuum and other common security-restricted operation users do not do so, so they are unaffected.
