GHSA-gm5x-hpmw-xpxg Silverstripe CMS information disclosure

• Packagist silverstripe/cms: <= 4.5.0 (no fix yet) • Packagist silverstripe/framework: >= 4.0.0, < 4.4.7 → fixed in 4.4.7 • Packagist silverstripe/framework: >= 4.5.0, < 4.5.4 → fixed in 4.5.4

In SilverStripe through 4.5.0, a specific URL path configured by default through the silverstripe/framework module can be used to disclose the fact that a domain is hosting a Silverstripe application. There is no disclosure of the specific version. The functionality on this URL path is limited to execution in a CLI context, and is not known to present a vulnerability through web-based access. As a side-effect, this preconfigured path also blocks the creation of other resources on this path (e.g. a page).
