If you wish to report a new security vulnerability in PostgreSQL, please send an email to security@postgresql.org. For reporting non-security bugs, please see the Report a Bug page.
The PostgreSQL Global Development Group (PGDG) takes security seriously, allowing our users to place their trust in the web sites and applications built around PostgreSQL. Our approach covers fail-safe configuration options, a secure and robust database server as well as good integration with other security infrastructure software.
PostgreSQL security updates are primarily made available as minor version upgrades. You are always advised to use the latest minor version available, as it will likely also contain other non-security related fixes. All known security issues are always fixed in the next major release, when it comes out.
PGDG 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 vulnerabilities by a range of criteria.
Vulnerabilities list which major releases they were present in, and which version they are fixed in for each. If the vulnerability was exploitable without a valid login, this is also stated. They also list a vulnerability class, but we urge all users to read the description to determine if the bug affects specific installations or not.
You can filter the view of patches to show just patches for version:
