GHSA-v55j-83pf-r9cq
Summary Rails has a possible XSS vulnerability in its Action View tag helpers ### Impact When a blank string is used as an HTML attribute name in Action View tag helpers, the attribute escaping is bypassed, producing malformed HTML. A carefully crafted attribute value could then be misinterpreted by the browser as a separate attribute name, possibly leading to XSS. Applications that allow users to specify custom HTML attributes are affected. ### Releases The fixed releases are available at the normal locations.
