CVE-2026-6472

A flaw was found in PostgreSQL CREATE TYPE handling for multirange types. The database failed to properly verify schema CREATE privileges during multirange type creation. An authenticated database user could exploit this issue to hijack queries that rely on search_path resolution for user-defined or extension-defined types, potentially causing execution of arbitrary SQL functions within the affected database context.

CVE-2026-6473

A flaw was found in PostgreSQL. An integer overflow in multiple server features allows an unprivileged database user to cause an undersized memory allocation that leads to an out-of-bounds write. This issue allows an attacker to execute arbitrary code as the operating system user running the database or, in applications that pass gigabyte-scale user inputs to the relevant database functions, to cause a segmentation fault, resulting in a denial of service.

CVE-2026-6473 (GCVE-0-2026-6473)

Vulnerability from cvelistv5 – Published: 2026-05-14 13:00 – Updated: 2026-08-25 12:05

Title

PostgreSQL server undersizes allocations, via integer wraparound

Summary

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 inputs to the relevant database functions, the application input provider may achieve a segmentation fault. Versions before PostgreSQL 18.4, 17.10, 16.14, 15.18, and 14.23 are affected.

Severity

8.8 (High)

CVE-2026-6475 (GCVE-0-2026-6475)

Vulnerability from cvelistv5 – Published: 2026-05-14 13:00 – Updated: 2026-05-15 03:56

Title

PostgreSQL pg_basebackup and pg_rewind can overwrite unrelated files of origin superuser choice

Summary

Symlink following in PostgreSQL pg_basebackup plain format and in pg_rewind 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 origin superuser, due to features like shared_preload_libraries. Hence, the attack has practical implications only if one takes relevant action between these commands and server start, like moving the files to a different VM or snapshotting the VM. Versions before PostgreSQL 18.4, 17.10, 16.14, 15.18, and 14.23 are affected.

CVE-2026-6477 (GCVE-0-2026-6477)

Vulnerability from cvelistv5 – Published: 2026-05-14 13:00 – Updated: 2026-08-25 12:05

Title

PostgreSQL libpq lo_* functions let server superuser overwrite client stack memory

Summary

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(..., result_is_int=0, ...) stores arbitrary-length, server-determined data into a buffer of unspecified size. Because both the \lo_export command in psql and pg_dump call lo_read(), the server superuser can overwrite pg_dump or psql stack memory. Versions before PostgreSQL 18.4, 17.10, 16.14, 15.18, and 14.23 are affected.

CVE-2026-6478 (GCVE-0-2026-6478)

Vulnerability from cvelistv5 – Published: 2026-05-14 13:00 – Updated: 2026-08-25 12:05

Title

PostgreSQL discloses MD5-hashed passwords via covert timing channel

Summary

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 passwords originating in upgrades from PostgreSQL 13 or earlier. Versions before PostgreSQL 18.4, 17.10, 16.14, 15.18, and 14.23 are affected.

CVE-2026-6479 (GCVE-0-2026-6479)

Vulnerability from cvelistv5 – Published: 2026-05-14 13:00 – Updated: 2026-05-14 15:26

Title

PostgreSQL SSL/GSS init causes denial of service, via uncontrolled recursion

Summary

Uncontrolled recursion in PostgreSQL SSL and GSS negotiation allows an attacker able to connect to a PostgreSQL AF_UNIX 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 18.4, 17.10, 16.14, 15.18, and 14.23 are affected.

CVE-2026-6575 (GCVE-0-2026-6575)

Vulnerability from cvelistv5 – Published: 2026-05-14 13:00 – Updated: 2026-05-14 15:26

Title

PostgreSQL pg_restore_attribute_stats accepts values that cause query planning to read past end of stats array

Summary

Buffer over-read in PostgreSQL function pg_restore_attribute_stats() 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 18.4 are affected. Versions before PostgreSQL 18 are unaffected.

Severity

4.3 (Medium)

CVE-2026-6637 (GCVE-0-2026-6637)

Vulnerability from cvelistv5 – Published: 2026-05-14 13:00 – Updated: 2026-05-15 03:56

Title

PostgreSQL refint allows stack buffer overflow and SQL injection

Summary

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 key and facilitates user-controlled updates to that column. In that case, a SQL injection allows a primary key update value provider to execute arbitrary SQL as the database user performing the primary key update. Versions before PostgreSQL 18.4, 17.10, 16.14, 15.18, and 14.23 are affected.

Severity

8.8 (High)
