Recent PostgreSQL Security Vulnerabilities
An information leak was discovered in postgresql in versions before 13.2, before 12.6 and before 11.11
CVE-2021-3393
4.3 - Medium
- April 01, 2021
An information leak was discovered in postgresql in versions before 13.2, before 12.6 and before 11.11. A user having UPDATE permission but not SELECT permission to a particular column could craft queries which, under some circumstances, might disclose values from that column in error messages. An attacker could use this flaw to obtain information stored in a column they are allowed to write but not read.
Generation of Error Message Containing Sensitive Information
A flaw was found in PostgreSQL in versions before 13.2, before 12.6, before 11.11, before 10.16, before 9.6.21 and before 9.5.25

The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability.
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
It was found that PostgreSQL versions before 12.4, before 11.9 and before 10.14 did not properly sanitize the search_path during logical replication. An authenticated attacker could use this flaw in an attack similar to CVE-2018-1058, in order to execute arbitrary SQL command in the context of the user used for replication.
SQL Injection
It was found that some PostgreSQL extensions did not use search_path safely in their installation script
CVE-2020-14350
7.3 - High
- August 24, 2020
It was found that some PostgreSQL extensions did not use search_path safely in their installation script. An attacker with sufficient privileges could use this flaw to trick an administrator into executing a specially crafted script, during the installation or update of such extension. This affects PostgreSQL versions before 12.4, before 11.9, before 10.14, before 9.6.19, and before 9.5.23.

CVE-2020-1720
6.5 - Medium
- March 17, 2020
A flaw was found in PostgreSQL's "ALTER ... DEPENDS ON EXTENSION", where sub-commands did not perform authorization checks. An authenticated attacker could use this flaw in certain configurations to perform drop objects such as function, triggers, et al., leading to database corruption. This issue affects PostgreSQL versions before 12.2, before 11.7, before 10.12 and before 9.6.17.
AuthZ
The pg_ctlcluster script in postgresql-common in versions prior to 210 didn't drop privileges when creating socket/statistics temporary directories
CVE-2019-3466
7.8 - High
- November 20, 2019
The pg_ctlcluster script in postgresql-common in versions prior to 210 didn't drop privileges when creating socket/statistics temporary directories, which could result in local privilege escalation.
Improper Privilege Management
A flaw was discovered in postgresql versions 9.4.x before 9.4.24, 9.5.x before 9.5.19, 9.6.x before 9.6.15, 10.x before 10.10 and 11.x before 11.5 where arbitrary SQL statements
CVE-2019-10208
8.8 - High
- October 29, 2019
A flaw was discovered in postgresql versions 9.4.x before 9.4.24, 9.5.x before 9.5.19, 9.6.x before 9.6.15, 10.x before 10.10 and 11.x before 11.5 where arbitrary SQL statements can be executed given a suitable SECURITY DEFINER function. An attacker, with EXECUTE permission on the function, can execute arbitrary SQL as the owner of the function.
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
It was discovered that PostgreSQL versions before 10.5
CVE-2018-10925
8.1 - High
- August 09, 2018
It was discovered that PostgreSQL versions before 10.5, 9.6.10, 9.5.14, 9.4.19, and 9.3.24 failed to properly check authorization on certain statements involved with "INSERT ... ON CONFLICT DO UPDATE". An attacker with "CREATE TABLE" privileges could exploit this to read arbitrary bytes server memory. If the attacker also had certain "INSERT" and limited "UPDATE" privileges to a particular table, they could exploit this to update other columns in the same table.
