Summary

Rails is a web-application framework. There is a possible XSS vulnerability when using the translation helpers in Action Controller. Applications using translation methods like translate, or t on a controller, with a key ending in "_html", a :default key which contains untrusted user input, and the resulting string is used in a view, may be susceptible to an XSS vulnerability. The vulnerability is fixed in 7.1.3.1 and 7.0.8.1.

Fencer Vulns keeps one entry per vulnerability: the CVE id wins, then GHSA, and records that alias each other are merged, except that two CVEs always keep separate entries. The same data is available as JSON.

The maintainers of rails/rails published their own advisory on GitHub. Reviewed sources take precedence over it.

CPEs and fixed versions use Anchore's correction of NVD's data: Added CPE configurations because not yet analyzed by NVD.
