BIT-POSTGRESQL-2026-6575 PostgreSQL pg_restore_attribute_stats accepts values that cause query planning to read past end of stats array

Buffer over-read in PostgreSQL function pgrestoreattributestats accepts array values of unmatched length, which causes query planning to read past end of one array. This allows a table maintainer to infer memory values past that array end. Within major version 18, minor versions before PostgreSQL...

BIT-POSTGRESQL-2026-6479 PostgreSQL SSL/GSS init causes denial of service, via uncontrolled recursion

Uncontrolled recursion in PostgreSQL SSL and GSS negotiation allows an attacker able to connect to a PostgreSQL AFUNIX socket to achieve sustained denial of service. If SSL and GSS are both disabled, an attacker can do the same via access to a PostgreSQL TCP socket. Versions before PostgreSQL 18....

BIT-POSTGRESQL-2026-6478 PostgreSQL discloses MD5-hashed passwords via covert timing channel

Covert timing channel in comparison of MD5-hashed password in PostgreSQL authentication allows an attacker to recover user credentials sufficient to authenticate. This does not affect scram-sha-256 passwords, the default in all supported releases. However, current databases may have MD5-hashed...

BIT-POSTGRESQL-2026-6477 PostgreSQL libpq lo_* functions let server superuser overwrite client stack memory

Use of inherently dangerous function PQfn..., resultisint=0, ... in PostgreSQL libpq loexport, loread, lolseek64, and lotell64 functions allows the server superuser to overwrite a client stack buffer with an arbitrarily-large response. Like gets, PQfn..., resultisint=0, ... stores arbitrary-lengt...

BIT-POSTGRESQL-2026-6476 PostgreSQL pg_createsubscriber allows SQL injection via subscription name

SQL injection in PostgreSQL pgcreatesubscriber allows an attacker with pgcreatesubscription rights to execute arbitrary SQL as a superuser. The attack takes effect when pgcreatesubscriber next runs. Within major versions 17 and 18, minor versions before PostgreSQL 18.4 and 17.10 are affected...

BIT-POSTGRESQL-2026-6475 PostgreSQL pg_basebackup and pg_rewind can overwrite unrelated files of origin superuser choice

Symlink following in PostgreSQL pgbasebackup plain format and in pgrewind allows an origin superuser to overwrite local files, e.g. /var/lib/postgres/.bashrc, that hijack the operating system account. It will remain the case that starting the server after these commands implicitly trusts the orig...

BIT-POSTGRESQL-2026-6474 PostgreSQL timeofday() can disclose portions of server memory

Externally-controlled format string in PostgreSQL timeofday function allows an attacker to retrieve portions of server memory, via crafted timezone zones. Versions before PostgreSQL 18.4, 17.10, 16.14, 15.18, and 14.23 are affected...

BIT-POSTGRESQL-2026-6473 PostgreSQL server undersizes allocations, via integer wraparound

Integer wraparound in multiple PostgreSQL server features allows an unprivileged database user to cause the server to undersize an allocation and write out-of-bounds. This may execute arbitrary code as the operating system user running the database. In applications that pass gigabyte-scale user...

BIT-POSTGRESQL-2026-6472 PostgreSQL CREATE TYPE does not check multirange schema CREATE privilege

Missing authorization in PostgreSQL CREATE TYPE allows an object creator to hijack other queries that use searchpath to find user-defined types, including extension-defined types. That is to say, the victim will execute arbitrary SQL functions of the attacker's choice. Versions before PostgreSQL...
