Require sprockets version 2.2.3, since 2.2.1 and 2.2.2 are vulnerable to an information leak attack. More Details Show archive.org snapshot

In our own investigations we found that Sprockets 2.2.3 is not vulnerable to CVE-2018-3760, despite the original advisory claiming so. Since no fixed sprockets versions were compatible with Rails 3.2, we've decided to freeze the dependency to 2.2.3, which has no vulnerability known to us.

Mar 20th, 2018: Not affected by sanitization CVEs

A vulnerability was disclosed for some Ruby sanitization gems like loofah ( CVE-2018-8048 Show archive.org snapshot ) and sanitize ( CVE-2018-3740 Show archive.org snapshot ). This also affects recent Rails versions, whose sanitize() helper depends on loofah.

We have confirmed that the sanitize() helper in Rails 3.2 is not affected by this issue.

Note that if your application uses one of the affected gems directly, you may still be affected and should update to the latest version of these gems.
