The PHP Security Advisories Database references known security vulnerabilities in various PHP projects and libraries. This database must not serve as the primary source of information for security issues, it is not authoritative for any referenced software, but it allows to centralize information for convenience and easy consumption.

The PHP security advisories database is free and unencumbered software released into the public domain.

To check your application's dependencies for known vulnerabilities, run composer audit from your project's root directory (the directory containing composer.json and composer.lock):

composer audit

Contributing security advisories is as easy as it can get:

• You can contribute a new entry by sending a pull request or by creating a file directly via the Github interface;

• Create a directory based on the Composer name of the software where the security issue exists (use symfony/http-foundation for an issue in the Symfony HttpFoundation component for instance);

• Each security issue must be saved in a file where the name is the CVE identifier (preferred) or the date when the security issue was announced followed by an increment (2012-12-12-1 for instance);

• The file is in the YAML format and must contain the following entries (have a look at existing entries for examples):

  • title: A text that describes the security issue in a few words;

  • link: A link to the official security issue announcement (HTTPS links are preferred over HTTP ones);

  • reference: A unique reference to identify the software (the only supported scheme is composer:// followed by the Composer identifier);

  • branches: A hash of affected branches, where the name is the branch name (like 2.0.x), and the value is a hash with the following entries:

    • time: The date and time in UTC when the security issue was fixed or null if the issue is not fixed yet (most of the time, the date of the merge commit that fixed the issue in the following format 2012-08-27 19:17:44) -- this information must be as accurate as possible as it is used to determine if a project is affected or not;

    • versions: An array of constraints describing affected versions for this branch (this is the same format as the one used for Composer -- ['>=2.0.0', '<2.0.17']).

• If you have a CVE identifier, add it under the cve key.

• Make sure your file validates by running php -d memory_limit=-1 validator.php from the root of this project. This script needs some dependencies to be installed via composer, so you need to run composer install before.

If some affected code is available through different Composer entries (like when you have read-only subtree splits of a main repository), duplicate the information in several files.
