The PostgreSQL Global Development Group (PGDG) takes security seriously. This allows our users to place their trust in PostgreSQL for protecting their mission-critical data.
The PostgreSQL Global Development Group follows a model that shares responsibility between PostgreSQL itself and its deployment environment, including hardware, operating system, and the application layer (programming language, frameworks and client libraries). The PostgreSQL documentation provides info on the inherent security features of PostgreSQL and how to securely configure and run PostgreSQL.
Security vulnerabilities can exist both in PostgreSQL and software within the PostgreSQL ecosystem, including client libraries, extensions, installers, and other utilities. This page walks through what is considered a security vulnerability in PostgreSQL, how to report PostgreSQL security vulnerabilities, and how fixes for security vulnerabilities are released.
Please note that the PostgreSQL Project does not offer bug bounties.
The PostgreSQL Project is a CVE Numbering Authority (CNA), working with Red Hat as our CNA Root. This allows us to assign our own CVE numbers and publish CVE records for PostgreSQL and closely related projects.
We will currently assign CVE numbers for the following projects upon request to cna@postgresql.org:
Additional projects may request inclusion on the list above by emailing cna@postgresql.org.
NOTE: The security team will only assign CVEs to projects when requested by members of the project. If you think you've found a security issue in a project other than PostgreSQL or it's packages and installers, please contact the security team for that project. See below for more details.
A security vulnerability in PostgreSQL is an issue that allows a user to gain access to privileges or data that they do not have permission to use, or allows a user to execute arbitrary code through a PostgreSQL process.
The PostgreSQL Security Team does not consider reports on actions a PostgreSQL superuser takes to be a security vulnerability. However, a report on an unprivileged user escalating to superuser generally qualifies as valid.
The PostgreSQL Security Team typically does not consider a denial-of-service on a PostgreSQL server from an authenticated, valid SQL statement to be a security vulnerability. A denial-of-service issue of this nature could still be a bug, and we encourage you to report it on the Report a Bug page.
Please do not report the lack of DMARC on postgresql.org mailing lists. This is by design.
For security vulnerabilities in PostgreSQL or any of the installers linked from the PostgreSQL download page, please email security@postgresql.org.
For reporting non-security bugs, please visit the Report a Bug page.
If you are unsure if an issue is a security vulnerability, please err on the side of caution and email security@postgresql.org.
Please see below for how you can report security vulnerabilities in PostgreSQL-related projects:
The PostgreSQL Project releases security fixes as part of minor version updates. You are always advised to use the latest minor version available, as it will contain other non-security related fixes.
A new PostgreSQL major release, which contains new features, has every prior security fix.
If you find a security vulnerability in PostgreSQL, the PostgreSQL Security Team will credit you in the release notes and register a CVE for the vulnerability. Please do not register a CVE independently of the PostgreSQL Security Team.
To receive notifications about security releases or other security related news, you can subscribe to the pgsql-announce mailing list. If you set your subscription to only include the tag Security, it will exclude all other announcements that are sent to this list.
The PostgreSQL Global Development Group believes that accuracy, completeness and availability of security information is essential for our users. We choose to pool all information on this one page, allowing easy searching for security vulnerabilities over a range of criteria. This includes:
You can find more detailed information about a security vulnerability by clicking on the links in the table below.
