Improper neutralization of quoting syntax in PostgreSQL libpq functions PQescapeLiteral(), PQescapeIdentifier(), PQescapeString(), and PQescapeStringConn() allows a database input provider to achieve SQL injection in certain usage patterns. Specifically, SQL injection requires…

A flaw was found in PostgreSQL versions before 13.1, before 12.5, before 11.10, before 10.15, before 9.6.20 and before 9.5.24. An attacker having permission to create non-temporary objects in at least one schema can execute arbitrary SQL functions under the identity of a…

When applying replicated changes for a row that is missing one or more columns, pglogical evaluates the affected table's default expressions on the subscriber. Because the apply worker runs at a privilege level equivalent to a PostgreSQL superuser in default installations, any…

The pglogical queue mechanism, used to convey out-of-band commands such as replicated DDL from a publisher to a subscriber, executes message payloads on the subscriber at the privilege level of the apply worker, which is equivalent to a PostgreSQL superuser in default…

postgresql before versions 10.4, 9.6.9 is vulnerable in the adminpack extension, the pg_catalog.pg_logfile_rotate() function doesn't follow the same ACLs than pg_rorate_logfile. If the adminpack is added to a database, an attacker able to connect to it could exploit this to…

Stack buffer overflow in PostgreSQL module "refint" allows an unprivileged database user to execute arbitrary code as the operating system user running the database. A distinct attack is possible if the application declares a user-controlled column as a "refint" cascade primary…

Use of inherently dangerous function PQfn(..., result_is_int=0, ...) in PostgreSQL libpq lo_export(), lo_read(), lo_lseek64(), and lo_tell64() functions allows the server superuser to overwrite a client stack buffer with an arbitrarily-large response. Like gets(), PQfn(...,…
