Use of a Broken or Risky Cryptographic Algorithm
The Windows installer for PostgreSQL 9.5 - 12 invokes system-provided executables that do not have fully-qualified paths
CVE-2020-10733
7.3 - High
- September 16, 2020
The Windows installer for PostgreSQL 9.5 - 12 invokes system-provided executables that do not have fully-qualified paths. Executables in the directory where the installer loads or the current working directory take precedence over the intended executables. An attacker having permission to add files into one of those directories can use this to execute arbitrary code with the installer's administrative rights.
Untrusted Path
It was found that PostgreSQL versions before 12.4
CVE-2020-14349
7.1 - High
- August 24, 2020

SQL Injection
Postgresql
CVE-2019-10209
2.2 - Low
- October 29, 2019
Postgresql, versions 11.x before 11.5, is vulnerable to a memory disclosure in cross-type comparison for hashed subplan.
Information Disclosure
A vulnerability was found in postgresql versions 11.x prior to 11.3
CVE-2019-10129
6.5 - Medium
- July 30, 2019
A vulnerability was found in postgresql versions 11.x prior to 11.3. Using a purpose-crafted insert to a partitioned table, an attacker can read arbitrary bytes of server memory. In the default configuration, any user can create a partitioned table suitable for this attack. (Exploit prerequisites are the same as for CVE-2018-1052).
Information Disclosure
A vulnerability was found in PostgreSQL versions 11.x up to excluding 11.3
CVE-2019-10130
4.3 - Medium
- July 30, 2019
A vulnerability was found in PostgreSQL versions 11.x up to excluding 11.3, 10.x up to excluding 10.8, 9.6.x up to, excluding 9.6.13, 9.5.x up to, excluding 9.5.17. PostgreSQL maintains column statistics for tables. Certain statistics, such as histograms and lists of most common values, contain values taken from the column. PostgreSQL does not evaluate row security policies before consulting those statistics during query planning; an attacker can exploit this to read the most common values of certain columns. Affected columns are those for which the attacker has SELECT privilege and for which, in an ordinary query, row-level security prunes the set of rows visible to the attacker.
Authorization
PostgreSQL versions 10.x before 10.9 and versions 11.x before 11.4 are vulnerable to a stack-based buffer overflow
CVE-2019-10164
8.8 - High
- June 26, 2019
PostgreSQL versions 10.x before 10.9 and versions 11.x before 11.4 are vulnerable to a stack-based buffer overflow. Any authenticated user can overflow a stack-based buffer by changing the user's own password to a purpose-crafted value. This often suffices to execute arbitrary code as the PostgreSQL operating system account.
Buffer Overflow
** DISPUTED ** In PostgreSQL 9.3 through 11.2, the "COPY TO/FROM PROGRAM" function
CVE-2019-9193
7.2 - High
- April 01, 2019
** DISPUTED ** In PostgreSQL 9.3 through 11.2, the "COPY TO/FROM PROGRAM" function allows superusers and users in the 'pg_execute_server_program' group to execute arbitrary code in the context of the database's operating system user. This functionality is enabled by default and can be abused to run arbitrary operating system commands on Windows, Linux, and macOS. NOTE: Third parties claim/state this is not an issue because PostgreSQL functionality for COPY TO/FROM PROGRAM is acting as intended. References state that in PostgreSQL, a superuser can execute commands as the server user without using the COPY FROM PROGRAM.
Shell injection
postgresql before versions 11.1, 10.6 is vulnerable to a to SQL injection in pg_upgrade and pg_dump via CREATE TRIGGER
CVE-2018-16850
9.8 - Critical
- November 13, 2018
postgresql before versions 11.1, 10.6 is vulnerable to a to SQL injection in pg_upgrade and pg_dump via CREATE TRIGGER ... REFERENCING. Using a purpose-crafted trigger definition, an attacker can cause arbitrary SQL statements to run, with superuser privileges.
SQL Injection
A weakness was found in postgresql-jdbc before version 42.2.5
CVE-2018-10936
8.1 - High
- August 30, 2018
A weakness was found in postgresql-jdbc before version 42.2.5. It was possible to provide an SSL Factory and not check the host name if a host name verifier was not provided to the driver. This could lead to a condition where a man-in-the-middle attacker could masquerade as a trusted server by providing a certificate for the wrong host, as long as it was signed by a trusted CA.
Improper Validation of Certificate with Host Mismatch
