DLA-2403-1 rails -- LTS security update
- Date Reported:
- 09 Oct 2020
- Affected Packages:
- Security database references:
- In the Debian bugtracking system: Bug 970040.
In Mitre's CVE dictionary: CVE-2020-15169.
- More information:
A potential Cross-Site Scripting (XSS) vulnerability was found in rails, a ruby based MVC framework. Views that allow the user to control the default (not found) value of the `t` and `translate` helpers could be susceptible to XSS attacks. When an HTML-unsafe string is passed as the default for a missing translation key named html or ending in _html, the default string is incorrectly marked as HTML-safe and not escaped.
For Debian 9 stretch, this problem has been fixed in version 2:22.214.171.124-1+deb9u4.
We recommend that you upgrade your rails packages.
