Pádraic Brady has a new post today proposing that what the PHP ecosystem needs is a way to better publish security disclosures in a format that's easy to parse and deal with.
This is a branch off from a separate discussion on the PHP-FIG mailing list about other ways the Framework Interoperability Group can encourage and foster wider interoperability among its member projects (and by extension, the whole PHP community). I'll start by noting two interesting developments in recent months and one long standing best practice.
The two "interesting developments" he mentions are the relatively recently released SensioLabs Security Checker that uses you Composer file to find security issues and the new entry in the latest version of the OWASP Top 10 list for "Using Components with Known Vulnerabilities". The best practice he talks about is more around the timely/responsible disclosure of vulnerabilities and how some kind of decentralized tracking of these issues that puts the responsibility back on the developers of the tool and not on one tracking resource.
