JSON

Relative URLs starting with three slashes were incorrectly parsed, and a path-traversal “/…/” part in the path could be used to override the specified host. This could contribute to security problems in web sites. This vulnerability affects Firefox < 120, Firefox ESR < 115.5.0, and Thunderbird < 115.5.
